Reasons why the return lines are clogged, and where …
On a gravity-return system, there may not be enough height between the end of the main and the boiler water line to allow the condensate to return through a dry return. Or there may be risers dripping down into the wet return from upper floors. If you use a dry return, steam might have access to those drip lines.
A two-pipe system, more commonly found on hot water boilers and newer steam boiler systems have a separate supply piping line to the radiators and a separate return piping line back from the radiators to the boiler. Vents are only installed on the piping to and from the steam boiler, not the radiators.
Steam Heat Condensate Piping, Pumps, Return LInes Our photograph at left shows a leaky steam condensate return line close to the steam boiler. This steam condensate line leak has been dripping for more than a decade. Unlike a hydronic heating boiler system, because the pressure in the steam condensate return line is low, the leak was not
2019-1-14 · Mechanical Return— Steam heating systems in which the height between the end of the main and the boiler water line (drip connection) is insufficient for gravity return of condensate back to the boiler A condensate pump provides the mechanical means for condensation return. No Pressure Return— Actually a dry return below the boiler water line.
2006-12-6 · Pipe Sizing Steam Supply and Condensate Return Lines Definitions Steam mains or mains carry steam from the boiler to an area in which multiple steam-using units are installed. Steam branch lines take steam from steam main to steam-heated unit. Trap discharge lines move condensate and flash steam from the trap to a return line.
Why return condensate to the boiler? - Plant Services
2010-4-21 · With high energy costs, you must return as much condensate as possible to the boiler plant for reuse. The benchmark for optimal condensate return is as high as 90%. This is possible if the plant doesn’t use direct steam injection for process applications.
These tutorials explain the principles of steam engineering and heat transfer. They also provide a comprehensive engineering best practice guide covering all aspects of steam and condensate systems; from the boiler house and steam distribution system up to the point of use; through the condensate recovery system and returning to the boiler.
2017-6-3 · AVACE AACR CE Energy Tips: STEAM Stea i heet Suggested Actions Reduce operating costs through maximizing the return of hot condensate to the boiler. Consider the following actions: If a condensate return system is absent, estimate the cost of a condensate return and treatment system (as necessary) and install one if economically justified.
