ABSTRACT:
The present invention relates to a high speed burning furnace and incinerator, particularly to a high speed burning furnace and incinerator capable of completely burning pulverized coal in the burning furnace, separating the ash produced by the combustion, injecting the said flame into the incinerator, and then completely burning the waste products. The main feature of this invention resides in that a heavy oil or a pulverized coal can be mixed with a primary air flow and injected into the burning furnace so as to introduce a rapidly revolving secondary air flow from tangential air flow inlets on an inner pipe to help combustion and thus a complete combustion can be effected and the flame can be intensified. This intense flame is introduced into the incinerator to completely burn the waste products sent into the incinerator by a conveyer through a preheating chamber. Tangential air inlets and a radiating whirling sheets are provided on the inner pipe of the incinerator so as to enable a primary air flow and a secondary air flow in the incinerator to carry the waste products under combustion and to result in the continuous revolving of the waste products and thus the time duration of combustion can be lengthened and more complete combustion can be effected. Besides, an ash handling equipment is provided in this invention so that the plugging of pipes and the atmospheric pollution can be prevented, and the operation of the incinerator can be optimized.
