1. Saving land;

The fuel and fly ash are transported in cans and airtight, without dust pollution and coal storage and slag yard, which effectively improves the utilization rate of the land and saves more than 50% of the land.

 

2. Pollutant discharge concentration of huayuan suspended fluidized large-scale boiler is:

Soot 10 mg/Nm3;

SO 50 mg/Nm3;

100 mg/Nm3 NOx;

After combustion, the ash can be collected by airtight dry gas ash extraction system and can be used as the raw material for the production of air filler and cement.

 

3. The advantages of large-scale boilers are environmental protection, energy conservation and high efficiency. The effective utilization of coal resources makes the boiler's burndown rate reach more than 98%, and the thermal efficiency of the boiler operation is 86%~89%.

 

4. It is convenient to adjust the load;

The load of the large boiler can be adjusted arbitrarily in the range of 35% to 110%, which can achieve the effect of economic operation.

 

5. Low operating cost and high degree of automation; 

Save human resources, raw coal boiler per shift 6-7 people, and large boiler per shift only 2 operators.Save more than 20% on fuel.The labor intensity of fully automatic operating stoker is reduced, and the industrial sanitary conditions are greatly improved.
