Energy Conservation: Boiler Flue Baffling

摘要

The report reviews the principles of heat transfer as the affect the use of energy in boilers and furnaces whose primary use is space heating in residential and commercial types of buildings. The report summarizes some of the data available which measure the possible gain in heat transfer efficiency resulting from various designs of boiler flue baffles in actual use. These designs range from the crudest obstacles placed in the flues of boilers to more recent and realistic designs based on engineering concepts. Reductions in stack temperatures measure improvements in heat transfer efficiency. The study considers also problems of back pressure which can result from baffling. (ERA citation 11:020703)
