Abstract
Boiler fuel is exposed to a flow of pulsating hot gas and sonic energy from a pulse jet engine for classifying fuel particles with uniform size and moisture content. A second pulse jet engine directs a continuous flow of pulsating hot gas and sonic energy onto those surfaces of heat exchangers which are exposed to the boiler heating gas, for cleaning the heat exchanger surfaces. Another pulse jet engine is disposed in the exhaust stack for heating stack gas, for increasing chemical efficiency of emission control systems, while permitting greater extraction of usable heat from stack gas while inside the boiler.
