After holding the accumulation of heat of heat-accumulating area 320 of heat-storage type burner 300, fume afterheat is stored in heat storage 320, the heat storage after heat exchange
Temperature is increased to 900 DEG C or so, the low-temperature flue gas near zero pollutant discharge after heat exchange, after reversal valve commutation, air and pyrolysis gas
Mix from this burner mixing region 310, through the accumulation of heat of heat storage 320 so that mixture temperature reaches 800 DEG C, and in burner body 310
Catalysis burning is carried out, through the flue gas pollutant near-zero release after catalysis burning, so circulation, by the heat-storage type burner at two ends
300 continual reversing combustions so that the house refuse in pyrolysis space under the condition of high temperature, is endlessly pyrolyzed all the time
Going out pyrolysis gas carries out body of heater consumable, and unnecessary pyrolysis gas can be used to generate electricity and heat supply with the coal gas after pyrolytic carbon gasification.
