　　The hot blast stove adopts the method of direct combustion. After high purification treatment, hot blast is formed, which is in direct contact with the material for heating, drying or baking. The fuel consumption of this method is about half of that with steam or other indirect heaters. Therefore, the direct high-purification hot air method can be used without affecting the quality of the drying product.

　　Six advantages of hot blast stove:

　　1. Reduce costs, use bituminous coal as fuel, and the black background of flue gas is low;

　　Second, the heat supply is stable, and the output of compound fertilizer is increased;

　　3. Solve the problem of high water content and agglomeration of compound fertilizer;

　　Fourth, the high degree of automation can reduce the labor intensity of workers;

　　5. High-grade auxiliary machine accessories;

　　6. Safe, reliable, environmentally friendly and pollution-free.
