PURPOSE: To shorten the time required to extinguish a fire when liq. fuel is burned by a wick combustion system, by forming a combustion part with combustion tubes contg. a wick and by connecting a compressing mechanism for forcing back liq. fuel to the feed side to the combustion tubes.
CONSTITUTION: Plural fuel feeding nozzles 2 are fitted to the outside of a 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 top of the evaporator 1 and packed with a catalyst to form catalyst beds 5. Liq. fuel is burned in combustion tubes 13 by a wick combustion system, so the suitability of the liq. fuel to initial firing is improved as compared with other combustion system. Since the liq. fuel is forcedly fed to to wicks 14 in the tubes 13 with a fuel feeding pump 11, the feed of the liq. fuel can be freely controlled and energy for combustion (quantity of heat) can be regulated.
