PURPOSE:To eliminate generation of tar and enable excellent gasification and combustion of fuel for an extended period of time to be achieved by an arrangement wherein a gasification cylinder is heated uniformly by circulating high temperature air flow for combustion caused in a draft passage. CONSTITUTION:Air for combustion is forcibly ejected through an air blast port 2 into a cylindrical member 1, and at the same time, a fuel oil is injected through a fuel oil supply pipe 12 into an opening 4 formed at the leading end of a gasification cylinder 3. Since the air for combustion flowing through a draft passage 5 without being heated directly by the flame produced by gasification and combustion of fuel is continuously supplied as high temperature hot air into the gasification cylinder 3, the whole cylinder 3 is heated by the high temperature air for combustion to a uniform temperature. Consequently, the gasification cylinder 3 is maintained under a uniformly heated condition so that the fuel oil injected through the fuel supply pipe 12 and atomized on the side of leading end of the gasification cylinder 3 may not deposit tar. |
