PURPOSE:To prevent a vaporizing surface from the deposit of tar to thereby ensure a stable combustion over an extended period, by coating a heat resistant inorganic paint having a hydrocarbon-dissolved catalyst over a metallic vaporizing cylinder surface having a roughened vaporizing surface to maintain the temperature of vaporizing surface higher than a specific temperature. CONSTITUTION:When the temperature of vaporizing cylinder 8 is elevated above 350 deg.C by energizing a preheating heater 9, a motor 4 is actuated to thereby turn a cone 5, a shake-off disk 6 and an agitating blade 7. Upon the starting of a turbo-fan 10 producing an air pressure, a primary and a secondary combustion air flow inside and outside a vaporizing cylinder 2. A fuel pump is actuated simultaneously with the start-up of air blowing, and a liquid fuel is supplied to a cone 5 through a supply pipe 14, the fuel is converted into an oil drop 18 of micro- particles and then scattered towards a vaporizing surface 15. In the meantime, the vaporizing surface 15 which has undergone a surface roughening treatment beforehand is coated with a phosphate-based heat resistant inorganic paint containing 10wt% of zeolite containing rare earth and baked, and its emissivity is 0.9. |
