Room and Hun Qi cooling chamber, the Hun Qi cooling chamber is burnt to be arranged between the combustion chamber and ash-storing bin, for by kiln discharge exhaust gas and
High-temperature fuel gas hybrid cooling from combustion chamber；The top of the ash-storing bin is provided with exhanst gas outlet, for by the mixed gas
Cool down indoor gas discharge；It is provided in the upper of furnace body for by cold air or the exhaust gas discharged by the exhanst gas outlet
Cryogenic inert cold air after reprocessing is sent into the air inlet of the furnace interior, and the air inlet is prepared via double-layer stainless steel
Fire trough and the combustion chamber.
The pneumatic diffusion valve of high temperature is provided at the top of the furnace body, for balancing the pressure in furnace body.
Be additionally provided with auxiliary equipment above the lower section of the coal powder entrance, furnace body, the auxiliary equipment include access hole,
Peep hole, venting, pressure measurement and temperature measuring point, to monitor the operating parameter of coal-powder boiler.
Furnace body is made by using high temperature stainless steel material in the utility model, and insulating layer is set outside furnace body, simultaneously
The exhaust gas of limekiln discharge is utilized after reprocessing as coal-powder boiler cryogenic inert circulating cold air, so as to control oxygen in stove dense
Degree and temperature play the effect of temperature-controlling energy-saving lowers consumption.The coal-powder boiler floor space of the utility model is small, safe, automatic
Change degree is high, realize coal dust noncoking, high combustion efficiency, temperature control control oxygen effect be good in combustion, high degree of automation,
Resource circulation utilization.
