PURPOSE:To prevent the occurrence of deficiency in evaporation of fuel and to prevent production of irritating odor, by a method wherein a flame stabilizing mechanism is provided, a quantity of heat, by means of which evaporation of the fuel is effected, is not only fed from a recirculating flow, but also is fed from flame stabilizing provided to a fuel feed part. CONSTITUTION:In a fuel feed part, the air injected through a hole 11 for flame stabilizing is collided with a flame stabilizing plate 12, and velocity of flow is decreased. A part of fuel fed through a nozzle 5 is drawn therein to form a stabilized flame on the flame stabilizing plate 12. Out of a quantity of heat required for evaporation of fuel, an amount, by which a quantity of heat produced by a recirculating flow is short, can be compensated by regulating an amount of a stabilizing flame formed on the flame stabilizing plate 12 through variation of the size and the number of holes for flame stabilizing. This enables the feed of an evaporating heat to which a quantity of heat imparted only from a recirculating flow is insufficient, prevents the occurrence of deficiency in evaporation, and enables prevention of production of irritating odor after fire extinguishing. |
