Waster Heat Boiler Flue Regulations

Waste Heat Reduction and Recovery for Improving Furnace

For most heating equipment, a large amount of the heat supplied is wasted in the form of exhaust or flue gases. These losses depend on vari-ous factors associated with the design and operation of the heating equipment. This technical brief is a guide to help plant operators reduce waste heat losses associated with the heating equipment.

Thus you would be allowed 900 sq.ft. of boiler heating surface area for the wood fired unit and still be below the 90 bhp permitting threshold in 5-401 of the regulations. Since most boiler manufacturer's get a boiler horsepower out of 5.5 or 6 sq.ft. their bhp rating is likely well over 90 bhp but by our definition it would still be less.

Heat Recovery Flue Gas | Waste heat recovery system | exodraft

An flue gas heat exchanger reduces the temperatures in the flue gas flow. The resulting energy can be reused almost loss-free with a high degree of efficiency. The possibilities are not only limited to the use for heating or the heating of domestic hot water. Even manufacturing processes that require a high temperature can be supported in this way.
