PURPOSE: To improve the suitability of liq. fuel to initial firing and to obtained stable flames during combustion by facing the liq. fuel jetting holes of fuel jetting pipes to the inside of a combustion part made of a catalytic porous structure and by connecting the fuel jetting pipes to a fuel feeding pump.
CONSTITUTION: Plural nozzles 2 are fitted to the outside of circular fuel evaporator 1 and mixed liq. fuel consisting of methanol and water is fed from the nozzles 2. A burner 3 is placed under the evaporator 1 and the liq. fuel is gasified by heating with the burner 3. Plural reaction tubes 4 are connected to the of the evaporator 1 and packed with a catalyst to form catalyst beds 5. Liq. fuel is forcedly fed to a catalytic porous structure 16 in the burner 3. Since the structure 16 itself forms a wick-like combustion part, stable flames can be obtd. by the catalytic action. The suitability of the liq. fuel to initial firing can also be improved by the catalytic action.
