Abstract:
A volatile liquid fuel combustion system for substantially reducing harmful products of combustion, said system comprising, in combination:a. An enclosed vessel containing a quantity of volatile liquid fuel;b. means for extracting gaseous vapor from said fuel and mixing said vapors with combustion supporting gas;c. a thermal energy conversion means for oxidizing the fuel vapor-gas mixture;d. a thermal reactor into which products of combustion from said conversion means are discharged; said thermal reactor having an input for receiving the receiving the products of combustion and an output;e. flow limiting means connected to the output from said thermal reactor for discharging a first portion of said exhaust to the atmosphere and returning a second portion of said exhaust to said enclosed vessel;f. means for discharging said second portion at a temperature below the boiling temperature of the liquid fuel, into said vessel below the surface of the liquid fuel therein; andg. ultrasonic generator means for imparting ultrasonic energy to the second portion of said exhaust products of combustion.
