Coal powder sprayer (coal sprayer) is used for heating, heating, drying, annealing, tempering, steam, etc. It is an energy-saving coal powder sprayer with a steel shell externally. Its fuel is coal, serving as a key heat source for various industrial kilns. The coal powder sprayer is a combined machine of hammer mill crushing and centrifugal air supply, used for粉碎 coal lumps and directly spraying coal powder into combustion chambers for combustion in various reflecting furnaces, boilers, drying kilns, and焖火（annealing）kilns. It can be used as a配套 for various kilns in factories, mines, and enterprises. It can replace fuel oil, coal gas, and electric heat sources, thereby saving up to 50% of energy, significantly reducing costs, pollution indices, labor intensity, and improving economic benefits.
