The Clayton Advantage In Boiler Efficiency The Clayton Steam Generator has been designed to provide high quality, dry steam, rapidly and efficiently.
Ergy, which is lost out the exhaust stack on a typical boiler, a condensing boiler gains in efficiency. Naturally, The prime candidates for condensing boilers are low temperature systems, such as snow melt
Design and lower stack temperature, is able to capture the latent heat of ClearFire’s efficiency under “traditional” hot water conditions is also outstanding. CLEARFIRE BOILER. Model CFLC ClearFire Commercial Boilers 29
It is not uncommon for the gross stack temperature (flue gas temperature) of a condensing boiler to be 200°F or lower. This is in Reduction in boiler efficiency can be accomplished by maintaining the temperature of water returning to the boilers at 140°F or
Use Feedwater Economizers for Waste Heat Recovery Generally, boiler efficiency can be increased by 1% for every 40°F reduction in flue gas temperature. By Determine the stack temperature after the boiler has been tuned

Boiler efficiency can be improved by incorporating an excess air trim loop into the boiler controls. stack gas temperature, and boiler combustion efficiency. An automatic oxygen trim control system minimizes operating costs through ensuring
Energy Tips – Steam An often-stated rule of thumb is that boiler efficiency can be increased by 1% for each 15% reduction in excess air or 40°F reduction in stack gas temperature. Example A boiler operates for 8,000 hours per year and consumes 500,000 million Btu
By condensing this water and lowering the stack temperature, 98% efficiency can be reached. Some heat pump supplement boilers can achieve this. Hot Water Boiler Summary
Sensible heat loss is detrimental to boiler efficiency. A stack temperature lower than 300F (149C), although possible, requires significant air heater surface, a substantial support structure and is prone to dew point condensation, fouling
Boiler Energy Efficiency & Overview of Economizers May 2008 Presented by: Sunil Kumar, P.Eng. GENIVAR Conventional: final stack temperature above dew point temperature (utilize sensible heat only) Condensing: recover energy from latent (primary) and

“O’Brien Boiler Services help businesses run better everyday” TIP SHEET Get the best efficiency from your boiler by understanding stack temperature.
It is not uncommon for the gross stack temperature (flue gas temperature) of a condensing boiler to be 200°F or lower. This is in Reduction in boiler efficiency can be accomplished by maintaining the temperature of water returning to the boilers at 140°F or
Energy Tips – Steam Stack Gas Temperature °F Boiler 78 to 83% 350 to 550 • Determine your boiler capacity, average steam production, combustion efficiency, stack gas temperature, annual hours of operation, and annual fuel consumption. • Identify in-plant uses for heated
The exceptional efficiency which results is evidenced by the unusually low stack temperature. DYNATHERM efficiency ratings to 90.9%. Stack temperatures range from 240 to 370 o A Honeywell L4006A Aquastat senses the low temperature limit of the boiler. Since a steam boiler is not full of
