CN2289954Y - Radiation step multi-arched life rubbish incinerator - Google Patents

Abstract

The utility model relates to a rubbish incinerator. The acute angle between the plane surface of fire grate of the rubbish incinerator and the horizontal plane is 0 DEG-30 DEG. The fire grate is that the through hole of the fireback is communicated with the lower air channel chamber. The hearth above the fire grate is the step multi-arched shape. The hearth is communicated with the air preheated zone via the channel for exhausting the smoke. The hot air form the air preheater though the hot-blast main enters into the air channel chamber, penetrates though the rubbish batch layer, and enters into the hearth. The incinerator adopts naked light burning processes. The handling capacity of the rubbish is higher, the blowdown comes up to the standards, the heat utilization ratio is high, the fabrication cost is lower, and the serviceable life is longer.
