The U.S. oil industry is trying to do more with less, as operators seek to maximize reservoir production during a period of low oil prices. I can't speak for New Hollands. In 2011, I had a new combi boiler installed to replace an old back boiler and now have concerns that the flow and return were mixed up. I find the return pipe has popped out a couple of times. 1% of all proceeds go to fund carbon removal. In many hydronic systems, theres a need to divide the overall system flow into equal streams that pass through several identical components. He added a drain of to the left pipe. Nowadays with combi boilers, sealed systems and bottom opposite end fed radiators, it isnt as crucial as it used to be. If it is the return heating up first I'd be getting the plumber back straight away to pipe it up right, obviously never tested and commissioned the boiler, certainly wouldn't use him again. Larger diameter tube, hose, pipe will have less resistance= more flow. Graphics credit: John Siegenthaler, An example would be multiple solar thermal collectors, as shown in Figure 2. Welcome, I hope you can find your solutions here. All you may be doing is swapping a trv from a flow pipe to the return. To improve steam system efficiency and reliability, engineers often focus primarily on the steam supply side, addressing problems such as piping leaks, steam trap leaks, and insulation. Nonthermal food processing technologies, such as X-ray and electron-beam irradiation, may be used to eliminate pathogens in raw foods, pasteurize delicate food products such as fresh produce, and perform phytosanitary treatment. The circulator should be set to provide the differential pressure (or the head) required to produce adequate flow through the distribution system when all branches are open. Reverse return piping is an important concept in hydronics technology. Figure 1 shows a simple representation of reverse return piping through two identical components, each in its own branch piping. The reverse return arrangement has the potential to create approximately equal flow resistance through each branch and produce flows that are closer to equal. in chapter 73: 730630: Iron or non-alloy steel (excluding cast iron); tubes and pipes (not seamless), welded, of circular cross-section, n.e.c. However, in a condensate return system, steam is usually the inducer. How are pumped condensate return lines handled, and how does that differ from the way flashing condensate return lines are handled? There will be an arrow on the body of the valve showing the flow direction. Unfortunately, a 3-in. This may be true for pumped return lines, but not for nonflashing or flashing lines. In addition, returning treated water enables the plant to more closely maintain a good chemical balance. JavaScript is disabled. Thanks for that, I think my diagram was confusing, the thin lines were only to indicate that there would be branches to each of the radiators not actually looping the flow/return pipe, you dont say what size the boiler is or rad loads but it might be a good idea to come of the boiler with some 28mm. In contrast, direct return piping is the normal way of connecting chilled water pipes. These, as well as other tools and online videos, are useful for studying how flash steam influences pipe size. Long stretches of straight ducts will be combined into fewer entities to improve throughput and save UPS. Then do the same for the Mens room named: DCW Mens Restroom. open condensate outlet control valves on equipment that allow steam to flow into the return header. Central Heating - Blocked 22mm return pipe? Problems As the branch valves close, the circulator automatically detects attempted increases in differential pressure and reduces speed to compensate. Thus, condensate removal via steam traps is crucial for steam system safety and reliability. This is a non-official document translation although based on the original article, "The Beacon: A Free Tool That Saves Lives. Sizing the pumped return lines is easy simply base the size on the acceptable pipe velocity for single-phase liquid flow. Low-flow compliant rate; 100% air-tested in production. JavaScript is disabled. Hi all, we've recently moved into a property and believe there is some kind of backflow in the heating system. A higher percentage of the total flow will pass through branch No. It is extremely difficult to ensure equal pressure drops in all segments by just relying on the reverse return piping setup, without balancing valves. Once the hot water cylinder is hot enough, the return will get warmer, until it becomes as hot as the above pipe. Learn different types of HVAC components used in residential and commercial buildings. Furthermore, most pipe installations deviate from the original design significantly due to installer quality, inspection quality, site conditions and other factors. The site owner may have set restrictions that prevent you from accessing the site. Why shouldn't I pipe in series? Rigid copper is often used for water supply lines within the home. Water boiled up beneath the bubble, it seethed and spouted. But, new buildings nowadays are using variable chilled water flow which makes the use of the reverse return piping setup questionable. They are both new holland. Although reverse return piping may be attractive, there are a few critical disadvantages associated with it. Reconnect all fuel lines and retest for any . The lines carrying nonflashing and flashing condensate have two-phase flow. The flash steam condenses when it mixes with other condensate in the return, and, if the return line is not suitably designed, hammer can occur when the void created by the discharged steam collapses. It may not display this or other websites correctly. You are using an out of date browser. The circulator is set to the differential pressure required at design load conditions (when all branches are open). In a steam supply system, violent water hammer occurs when slugs of liquid condensate close off the cross-sectional pipe area and are propelled by high-velocity steam against piping walls. The new condensate then backs up into the equipment, preventing flow into the steam trap; but more importantly, it waterlogs the equipment, thereby reducing heat or process performance. does sound like the flow and return are linked back to front. Cloudflare is currently unable to resolve your requested domain. So, reverse return piping doesnt seem like a good idea at this point. Water hammer occurs when slugs of liquid condensate fill the cross-sectional area of the pipe and are propelled by high-velocity steam against the pipe walls (Figure 6). CTRL + SPACE for auto-complete. If I understand this correctly, what you're saying is that for the 0.2 L/s scenario (as example), you could only have: I have a project where we'd like to put a kitchen in the living room to create an open plan. Unlike reverse return piping, direct return piping doesnt have a u-turn at the return pipe. PIPES HS CODES: WELDED PIPES AND TUBES: 7306: Iron or steel (excluding cast iron); tubes, pipes and hollow profiles (not seamless), n.e.c. On bi directional valve it looks like a capital L with arrowpoints on the ends. It promised to provide a balanced hydronic system. Hence, the first AHU that receives the chilled water supply is also the first AHU that provides the chilled water return. The pump flow should match the flow rate recommended for the protein skimmer to ensure maximum filtering efficiency. header, our consulting service team recommended the installation of a carefully placed flash vessel (Figure 17), to remove flash from the main header and redirect it to atmosphere. However, larger is always better. aircondlounge is a participant in the Stripe Climate. Visit https://aircondlounge.com/shop to see all digital products sold on aircondlounge. Visit https://aircondlounge.com/category/buyer-guide/ to see more guides and product recommendations. . Using different coloured tape is a simple yet effective method of differentiating between the flow and return pipes. . In systems with relatively short supply and return mains, the designer may elect to use the same pipe size for all mains. The distribution piping can make a complete loop around the inside of the building, starting and ending in the mechanical room. Water hammer may be generated by different steam or flash steam sources, far from or upstream of the convergence point of transport piping. The second scenario, blow-through from opened bypasses, typically occurs when traps are undersized for the available differential pressure, or are experiencing stall conditions. is that a combi? A flash vessel can mitigate severe hammering in a condensate return header, and can also be used for low-pressure flash recovery where the system equipment allows for some backpressure. We borrowed a machine lately which uses constant oil, plugged into double acting spool valve. Then at the end of boot up a snapshot is taken so that user space does not overwrite the boot up data. After the condensate leaves the trap, it discharges to a lower-pressure region and flashes. For longer circuits the temperature drop between flow and return pipe circuits can be between 5C and 10C. Equation 1 can be used to calculate the amount of flash steam (i.e., the percentage of condensate that flashes to steam) for the steam traps in Figure 10. The boiler I am looking at is the Glowworm Ultrapower sxi 170 running approx 22Kw of rads plus DHW to 2 bathrooms, 1 cloakroom, Kitchen and utility. Tight budgets can make prioritizing engineering projects difficult. In some plants, a significant amount of condensate is wasted. Thanks, I shall take a look in that case and follow that advice. Reverse return distribution systems that serve multiple heat emitters make sense when all of the following conditions are met: The loads are being supplied from a common circulator; The loads served require the same supply temperature; The loads served are widely dispersed around the building; and. The pipe that gets hot first is the one marked H Return, so is actually the flow pipe and I can trace it back to the 'flow' outlet on the boiler, but that's why I'm confused when I read the posts about pipes being the wrong way around at the boiler. Return pump pressure ratings are indicated by their pump curves in measures called Net Positive Suction Head Required (NPSHr). Risko, J. R., Steam Heat Exchangers Are Underworked and Over-Surfaced, Chemical Engineering, 111 (11), pp. How are condensate lines sized for nonflashing systems, and how does that differ from sizing returns when flash steam is involved? Iam not sure which side is the flow on your glow worm, Id hazzard a guess its on the left. Figure 9. Just take the end off the return and stick it in filler cap. They will make up the majority of the types you'll be writing. Can be installed in existing 1 or 3-hole counter configurations. Having equal number of fittings; as well as, lengths of pipe. my thinking is that the return on both sides of the 'T' may be of unequal flow rate therefore one side of the 'T' reducing the return flow of the other? thats wat happens after a night on the sauce. When condensate is discharged from a high pressure to atmosphere, a tremendous amount of flash steam can be generated. Problems By closing this message or continuing to use our site, you agree to the use of cookies. I think they are bulldog 2. Pursuit the truth and learn the fundamental ways to approach the chilled-water system. If it sensed the return in error, it would constantly trip the over- heat stat. Hi Ian, So no need to swap the 22mm F and R pipes over at the boiler then? Consider the mixing of flash or live steam with low-temperature condensate in a return line (Figures 15 and 16). Because the condensate cannot be discharged into the pressurized line easily, it is first discharged into a vented tank, from which the flash steam is removed. A steam trap has a clearly defined role to discharge noncondensable gases and condensate without leaking steam (Figure 5). These are the top selling digital products made by me and sold on aircondlounge. To produce chilled water, the refrigerant absorbs heat from the water and thus, chilling the water to about 6.7C (44F). Reverse return piping systems also have relevance in certain pumping and hydronic systems. Perhaps, they are the reason why many design engineers stop using the reverse return piping setup in the chilled water system. SAFETY FIRST | Fluid flowing through a pipe generally assumes a desirable flow profile at or near the center of the pipe. Despite being a relatively straightforward problem to put right, the various issues that this can cause will add extra work to a heating engineers already busy schedule. I reviewed and compared hundreds of air conditioners. The first effort to reduce hammer should be to identify then repair leaking steam traps and close all open bypasses. If condensate is not removed, then dangerous water hammer can occur in the steam supply system. All three types of condensate lines are shown in Figure 1. Due to their large size, ducts cannot be directly connected to regular pipes. Visit our updated. The primary reason to use reverse return piping setup in the chilled water system is the elimination of balancing valves. I've been working as a professional in the HVAC industry for more than 7 years, covering from design and installation to commissioning and maintenance. Graphics credit: John Siegenthaler, Figure 5 shows how proportional differential pressure mode operates on most currently available electronically commutated motor (ECM) circulators. The condensate is nonflashing between the steam-using equipment and the trap because the two pieces of equipment are at the same pressure. The new standard for local and district heating networks with outdoor pipe insulation: Ecoflex VIP combines the best heat loss performance for flexible foam insulation pipes on the market with outstanding flexibility. There is no loose part or rattling noise. For a better experience, please enable JavaScript in your browser before proceeding. Looking for a quick bit of advice since I'm trying to wrap my head around what work I need done. (a) Steam from either flashing, trap leaks, or opened valves in a condensate return line forms large pockets, even though the steam mass may be small. Getting a long kitchen sink waste across and out to main waste stack, Honeywell Evohome hot water control for new boiler, Electrician Talk | ElectriciansForums.net. But, you must be sure that no flashing condensate or live steam are discharged into the pumped return line. For a better experience, please enable JavaScript in your browser before proceeding. All Rights Reserved BNP Media. Looking for a quick bit of advice since I'm trying to wrap my head around what work I need done. Graphics credit: John Siegenthaler, Figure 3 shows an example of a reverse return distribution system that meets these requirements. How did you go about heating the extension in your original post? Here the return type will be the same as the type of whatever value is passed into the function. At any moment, he thought, he might scream. The silicone aerator and spray nozzles help optimize water flow performance, resist mineral deposit build-up, and are designed to be easily wiped clean. Since then, 180 issues for process industry workers have been published (available at www.sache.org). Hi Ian, So no need to swap the 22mm F and R pipes over at the boiler then? The collapse can be rapid creating a localized, extremely low-pressure void, which condensate races to fill. (b) The mass of condensate is relatively high, pulling heat from the steam, which causes the steam pockets to collapse, thereby creating a localized low-pressure void. Another situation in which reverse return piping is not needed is when multiple boilers are closely grouped together and piped to a common device such as a hydraulic separator, as illustrated in Figure 6. Since pumps alternate based on the pump controller, rather than based purely on hydraulics . For laminar flow, where Re is < 2,000, there is little mixing of the flowing fluid, and the flow velocity is parabolic; the Moody friction factor is expressed as f = 64/Re. What Mcarroll is saying is that at your pressure and flow the it doesn't make any appreciable difference between the two sizes. This decreases system head loss, which may, in turn, reduce circulator size. Therefore, any discussion regarding the importance of effective condensate recovery should consider basic economics. Some hydro gearboxes like Vario/Autopower don't like bubbles in the oil that you can get from a high level return port. In such cases, pinpointing the cause can be challenging, but it is always wise to first check for leaking traps or open bypass lines. It may not display this or other websites correctly. The direction is important on a column rad though I believe. 2015). 5862 (Nov. 2004). However, most people would not agree with that. Walter, J. P., Implement a Sustainable Steam-Trap Management Program, Chemical Engineering Progress, 110 (1), pp. This article was originally titled Reversing course in the November 2016 print edition of Plumbing & Mechanical. As always help on here is free, however if you think you have saved a decent sum of money why not click the link to find out about the charity we're currently supporting? It does make a difference in my opinion.. You must log in or register to reply here. Since it was not feasible to install a larger, 6-in. What is Stall?, TLV Co., www.tlv.com/global/US/steam-theory/stall-phenomenon-pt1.html. So, the initial cost of purchasing balancing valves can be eliminated. Heating & Plumbing Monthly Magazine (HPM), A day in the life of Hansgrohe UK Installer, Subscribe to Plumbzine (Our Weekly Newsletter), https://www.youtube.com/watch?v=PzPNu0p1bpo. At 145 psig, QSh = 336.0 Btu/lb; at 0 psig, QSl = 180.2 Btu/lb and QLl = 970.3 Btu/lb; and at 44 psig, QSl = 260.8 Btu/lb and QLl = 916.8 Btu/lb. Figure 8. equivalents could discharge into the 3-in. (Figure 3) He said when looking at the boiler, the return was on the left. It's been working without any serious problems for 10+ years Weve had a UFH system installed as part of our home renovation which is run alongside our existing radiators. 4349 (Jan. 2014). Up, up it climbed, throwing stilts of light at the cliff. So, in steam supply lines, it is the liquid water itself that induces the hammer. At Blue Plains AWTP seven Amacan P pumps are located at various locations (Fig.1)in the denitrification return sludge gallery sumps and are used for pumping drainage, wash down and potentially sludge and chemicals if a pipe breaks. When flash steam or small amounts of live steam are present in a condensate return, the volume of the steam pocket can be large even if the steam mass is small (due to steams much greater specific volume). Run the fuel pump until the fuel runs clear in the line. In a gravity return system, condensate does not flash between steam-using equipment and the steam trap, but does flash after being discharged from the trap to the collecting tank. which blows seals. The pipe is 12 feet long, and the difference in height between the beginning and endpoints of the pipe is equal to 3 feet. However, there is also a fourth category. header was sized for liquid flow without consideration of flashing condensate or leaking steam traps. That, in turn, can help you optimize production and maximize revenue and profits. Maximum volume flow through main pipes is determined by the maximum demand of the fittings and statistic demand based on the number and types of fittings and equipment supplied. I asked the installer which pipe was flow, and which was return (so that a magnetic filter could be added later). It isn't causing any damage its just inefficient. AGT - (1) agitator, used in drilling. This may be true for pumped return lines, but not for nonflashing or flashing lines. From such low pressure, the condensate must be pumped back to the boiler. The flow valves can be rotated 360 for adjusting the pipes and even be removed for filter maintenance. Not to forget, the reverse return piping setup was initially developed as an alternative to balancing valves due to cost and the difficulty of manual balancing. link to Qatar World Cup Stadium Air Conditioning System, https://aircondlounge.com/category/buyer-guide/. Flash volume calculations are especially important in the sizing of condensate return lines in order to maintain the desired pressure and velocity. It is valued because it does not come with health risks unlike other pipe materials, such as plastics, that can leach chemicals. they ran alongside each other and were intertwined. Check the capacity of installed condensate pumps in relation to return line flow rates. Same as why most heat only come with 15mm gas doesnt mean I can run it straight from the meter in 15mm 20m etc (at 15kw). Install a clear line in series at the fuel return hose to the engine return pipe. As shown in the picture above, the flow is the top pipe, which means, the pipe at the top of the central heating pipes going into the hot water cylinder, will heat up first. What is Water Hammer? TLV Co., Kakogawa, Japan, www.tlv.com/global/TI/steam-theory/what-is-waterhammer.html (2011). Usually, a significant portion of condensate exiting a steam trap flashes into steam upon discharge. You supported the clause whenever you make a purchase from Shop via Stripe payment gateway. The third scenario, condensate outlet control valves leaking large amounts of steam into the return header (Figure 11), may occur, for example, if heat exchange equipment is fouled and automatic settings in the controller override the level readings to keep the control valve open with the intended goal to obtain more heat. The online version of the article includes animated figures courtesy of TLV Corp. Condensate return systems can have a big impact on productivity, energy efficiency, and site reliability. Now, PIBCVs offer huge benefits in hydronic balancing. Most of the time, balancing valves are still needed which makes the additional return pipes pointless. Again, the first port of call should be to check that the existing cold mains and hot outlets are correctly installed, and different coloured tape can also come in handy here too. Figure 4. Because the non-discharged condensate brings about the water hammer, condensate is the inducing factor and the hammering is condensate-induced. An arbitrary type that could be anything: . This can lead to flow noise, weepage through valves that are supposed to be closed, and erosion of copper tubing. Check them out and see which products fit your needs. trace_instance=foo,sched_switch,sched_waking ftrace_boot_snapshot=foo The above creates a "foo" instance at early start up and enables the sched_switch and sched_waking events. On a long drive once, in a hot summer, on a stretch of the Hume where rolling, sheep-ravaged hills the colour of bone gave glimpses of a long train full of wheat, my father-in-law explained train wheels to me: how they ran, how they turned, how they stayed on the tracks. yes Ive mixed up the flow and return before, fire up the boiler and then feel with your hand wether its the left or right hand pipe that gets hot first off the top of the boiler. The NPSHr rating for a pump indicates the minimum amount of pressure required on the suction side of a pump to avoid cavitation. Corrosion-resistant plastic lined piping systems are used for certain waste carrying applications. 5168447 9. Return pumps flow should be 5-10x aquarium volume every hour. COPYRIGHT 2023 AIRCONDLOUNGE DOTCOM. I have a project where we'd like to put a kitchen in the living room to create an open plan.
