To eliminate problems in a garbage incinerator wherein unburned garbage is left, deterioration of combustion efficiency is generated and pollution of ground-water is generated after embedding ash.
This incinerator for burning garbage including organic combustible material, furthermore, for burning cinders including combustible material till it becomes melted slug and waste gas is provided with a housing 10, a hopper 20 for guiding garbage into the housing, a combustion cage 30 having grid structure, a plurality of guide plates 40, a plurality of bulkhead 50 forming a normal circulation passage 1 and a reverse circulation passage II, an ash receiver plate 60 for receiving the ash fallen from a bottom part of the combustion cage, a plurality of air lead-in pipes 70 for leading primary air into the housing, and a plurality of circulation pipes 80 provided in one end of each of the air lead-in pipes to circulate the wasted gas inside the housing. With this structure, the ash on the ash receiver plate is continuously heated by cooperation of an intake opening with a wasted gas discharging opening, while extending flame downward in a bottom part of the combustion cage, and the waste gas inside the housing is circulated to the normal flow passage, which is provided in an upper part, by the circulation pipe, and the incinerator having a melting function for repeatedly burning is thereby obtained.
