Energy system producing electricity, hot water and steam from combustible refuse

Claim 1

A refuse burner, energy generating system comprising in combination: a pulse-jet sonic burner, an inlet port for the introduction of refuse into said burner, a pulverizer for feeding small particles of refuse through said inlet port into said burner, means coaxially arranged with said burner for driving air and refuse introduced through said inlet port under pressure into and through said burner, a steam generator comprising a coil of fluid conducting tubing coaxially arranged with said burner within the path of movement of the driven air and refuse for receiving the burning gases of said burner for heating fluid in said tubing, a water jacket surrounding said generator in heat conductive relationship therewith for conducting water therethrough for heating by the burning gases passing through said generator, and a precipitator connected to said generator for removing the smoke and pollutant matters emitted by said generator prior to exhaustion to atmosphere, said burner comprising a generally cylindrical form employing a restriction along its length for creating high frequency pulsations in the flow pattern of the burning gases passing therethrough.
