Abstract: This invention provides a refuse incinerator capable of extinguishing smoke and odor of exhaust gas emitted from, combustion of the refuse just after incineration of the refuse is started. Exhaust gas outlets are provided in a furnace lid of the incineration furnace, an exhaust gas chamber is provided such that the furnace lid is used as part of a bottom wall thereof and an exhaust gas introduction pipe is provided to communicate between the exhaust gas chamber and a combustion chamber. Exhaust gas emitted into the exhaust gas chamber is introduced into the combustion chamber and burnt so as to extinguish the smoke and odor. Because the combustion chamber reaches high temperatures just after the incineration of the refuse is started, the smoke and odor of the exhaust gas are extinguished just after the incineration of the refuse is started.
