Abstract: PURPOSE:To enable an efficient gasification and mixed state to be obtained by a method wherein a combustion chamber and a gasification chamber are divided into an upper chamber and a lower chamber and many projecting pins projected into the gasification chamber are formed at a mixing plate having a mixture gas passage. CONSTITUTION:After many projecting pins 15 projected from a mixing plate 9 into a gasification chamber 13 are heated by a heater 1 when ignition is carried out, liquid fuel and combustion air are supplied. Accordingly, the liquid fuel and the combustion air entered the gasification chamber 13 are instantly heated within the gasification chamber 13. In addition, when ignited, since the projecting pins 15 always receive combustion heat from above through the mixing plate 9, the temperature within the gasification chamber 13 is stabled and at the same time the temperature at the bottom part of the gasification cylinder 2 is also stabilized. Accordingly, delay in gasification or large-sized molecules may not be generated. In addition, the combustion air is guided to the mixing passage 9 while circulating between many projecting pins 15, so that the mixing is promoted within the gasification chamber 13. With such an arrangement as above, it is possible to obtain an efficient gasification and mixing state from the raising time.
