Abstract:
The present invention provides a tunnel type garbage incinerator, which is characterized that the garbages are first classified into combustible and incombustible materials, then the combustible materials are loaded on a bogie and fed into the incinerating tunnel for incineration, the fore section of the incinerating tunnel is used for drying combustible materials, the middle section of the incinerating tunnel is used for the bleast incineration of the combustible material, the aft section of the incinerating tunnel is used for the cooling and output port of the incinerated materials or ashes. In which, the incinerating tunnel is furnished with blowers, flame igniting device, smoke processing device, and through proper arrangement of the components, the garbages can be completely combusted with minimal fuel oil consumption, furthermore, since the smoke is filtered before it is expelled, it does not produce air pollution.
