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.
Claims6
In a selective catalytic reduction system which contains catalytic surfaces for removing nitrous oxide from stack gas, the improvement comprising:
- a pulse jet engine disposed to direct pulsating hot gas and sonic energy on the catalytic surfaces for cleaning the surfaces.
In a boiler, where a fuel is combusted to generate a heated gas, and the heated gas is directed over heat exchanger surfaces and transfers heat to a fluid inside the surfaces, the gas thereafter entering an exhaust stack as stack gas for removal of a pollutant by an emission control system, the improvement comprising:
- a pulse jet engine disposed in the exhaust stack for generating pulsating hot gas and sonic energy for heating the stack gas for increasing chemical efficiency of the emission control system.
