Title: Liquid fuel vaporization apparatus
Inventor: NISHIMURA TAKASHI
IPC: F23K5/22
Filed: 1995-06-14
Abstract: PURPOSE: To restrict production of NOx and vaporize l iquid fuel using both of an electric heater and heat production upon combustion of a catalyst by providing the catalyst inside the electric heater and forming a flow passage inside the catalyst through which passage premixed gas comprising a mixture of air from a combustion air supply passage and fuel from a fuel supply passage passes. CONSTITUTION: Air is supplied from a combustion air supply passage 3 into a casing 2 to turn an electric heater 6 on. Combustion air and a catalyst 7 are heated with the electric heater 6, and once the catalyst 7 is heated up to temperature where catalyst combustion is started (e.g. about 250 to 350 deg.C), a controller forces liquid fuel (e.g. kerosine) to be injected from a fuel supply passage 4 through the nozzle 4a. Part of the liquid fuel is vaporized owing to the heat of the heated combustion air and the catalyst 7, and premixed gas of the vaporized fuel and the air is combusted with the catalyst 7 to increase temperature of the combustion air and the catalyst 7 and promote vaporization of the liquid fuel. Further, the liquid fuel is combusted with a catalyst structure 8 to raise catalyst combustion gas temperature for completing vaporization.
