PURPOSE:To enable fuel to completely be burned with less emission of smoke and remaining ashes enough to easily incinerate kitchen rubbish by placing a perforated plate in the lower part of a primary burning chamber, connecting an air intake and a fuel feed duct to its upper part, connecting a secondary air intake to a secondary burning chamber, and connecting smoke outlet to the upper end of the upper winding narrow. CONSTITUTION:As air is fed from an air intake 5 and a primary air intake 7, the fuel material 20 is burnt, and the resultant combustion gas is led out of a perforated plate 3 through the lowermost part of a cylindrical body 1 to a secondary burning chamber 1B where, upon receiving secondary air from a secondary air intake 12, the remaining unburnt fuel is burnt to be led away to a winding narrow 14. The winding narrow 14 acts to increase the amount of air fed through the secondary air intake 12 by accelerating the combustion gas and to help mixing of the air and burnt gas so as to completely burn unburnt components such as soot by increasing the length of the narrow and the time period over which the burnt gas travels the narrow.
