PURPOSE:To reduce the consumption of energy required to fire liq. fuel and to prevent the wasteful flow of liq. fuel and the contamination of the combustion part of a burner in which liq. fuel is burned, by putting a catalyst for ignition under the flame generating spots of the combustion part. 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. A catalyst 17 for ignition is fitted to combustion tubes 13 for liq. fuel so that liq. fuel can be fired in the initial stage without preheating with large electric power. Even when liq. fuel leaks out of the small holes 15 of the tubes 13 before ignition, it is captured by the lower catalyst 17 and is not dropped. |
