ABSTRACT:
Production of oxides of nitrogen during combustion of liquid fuel can be reduced by burning at relatively low temperatures of about 1400.degree. C., by first producing a special combustible gaseous mixture of superheated steam, fuel vapor, and combustion air. Water is fed (9) to the apparatus in quantities of about 2 to 4 parts for each part of fuel (10). Then the fuel is vaporized (8) in a stream of the superheated steam. This avoids fuel cracking and formation of long-chain hydrocarbons. Preheated air (13,14,15) is added (17) in slightly over stoichiometric proportions. The resulting mixture is burned (2) and the hot effluent is used to heat the evaporator (6,7,8) and the air preheating chamber (15), with a bypass (20) equipped with a throttle (22) being used for regulation of evaporator temperature. For start-up, an external hot air source (23) or electric heat (24) can be used. The remaining heat in the effluent can be captured in a conventional heat exchanger. Preferably, mixing occurs in a chamber (3) located on the opposite side of the combustion chamber (2) from the evaporator (6) and the air preheating chamber (15).
