In Reply to: Steam Trap Failure--Need help with school project posted by Jan Gudell on May 16, 2002 at 13:00:34:
How about remove scale from the boiler if any is in there.
: Hi all,
: I am a first year graduate student taking a class on pollution prevention strategies. Our semester project is to look at a live case-- a very old steam boiler system at a local high school. Students are asked to select one opportunity for improving (preventing energy losses) the system. The boilers are nearly 50 year old oil-fired low pressure sectional Bigelows, so you can imagine there are many problems with the system. Corrosion, water loss and age are the big factors working against this system.
: I decided to look at the premature failure of steam traps as the one problem I want to address.
: I'm asking for your help in coming up with some
: alternatives for solving the problem of early steam trap failure. Basically the system is fighting an endless battle against corrosion and age.
: The idea is to search for a range of creative responses that yield a range of soultions that vary in cost, ease of implementation and effectiveness. We're looking for "low hanging fruit" and "crown jewels."
: If you can think of some additional alternatives to my preliminary list, that'd be great.
: Remove old system and install circular hydronic hot water system
: Seal all leaks
: Run system continuously to avoid "cyclical" losses
: Flush it more frequently
: Install a deaerator
: Install a more effective demineralizer
: Test water quality more frequently
: Install steam trap monitors
: Provide additional water chemistry and systems training to boiler room crew
: Hire a full-time operations engineer
: Provide cleaner water
: Give financial bonus to employees who can improve system reliability and effciency
: Install higher quality steam traps
: Ensure steam traps are properly sized/located
: Use alternative chemistry--amines
: Take kitchen out of loop to avoid FDA regulations to allow switch of water chemistry
: Insulate buildingówalls, doors, cracks
: Install high efficiency windows
: Take advantage of solar radiation for heating rooms where possible
: Explore opportunities for venting air from warmer areas to cooler areas.
: Explore opportunities for cogeneration. Can waste heat from kitchen be used to provide additional heat to rooms?
: Install best condensate return system
: Install economizer
: Thanks for your help,
: Jan Gudell
