The coal powder spraying machine is a new type of coal-fired equipment for drying,annealing,tempering of boiler,steam,etc.. It sets multiple functions such as feeding, crushing and transportation in one and can complete these processes at one time. It grinds the coal and inject the pulverized coal into the combustion furnace at the same time. It can be well used in small coal fired boiler, reverberatory furnace, annealing furnace and drying furnace in Malleable steel factores, foundry plants, steel rolling plants, strip steel plants, cement plants and boiler plants. It can replace fuel, gas and electric thermal energy equipment, which can save 40-50% of energy.

Features of coal powder spraying machine:

1) Simple structure, compact layout, good quality pulverized coal, high combustion efficiency, low noise, easy maintenance, and simple operation

2) Easy ignition, easy control of the furnace temperature and stable product quality

3) The speed of outlet air can reach 70 M/S. The speed of air into the furnace can be 20-25 M/S.The outlet pressure can be 1300-1700pa, and the volume of outlet air is 750-2500M3.

4) By adjustment of second air fan, the coal is burned in reducing atmosphere. 

5) Automative operation, negative pressure technology, heat-recovery process, less pollution, low labor intensity

6) High thermal efficiency, no exhaust emissions
