casting iron boiler grate bar four jaw flake grate bars little leakage

Advantages of the small scale grate:

1. The coal seam is in contact with the entire grate surface, and the chain is not directly heated, and the operation is safe and reliable;

2. The gap between the grate is very small, and there is little leakage;

3. The furnace row is thinner, the cooling condition is good, and the furnace can be replaced without stopping the furnace;

4. Since the chain is a flexible structure, when the tooth shape of the sprocket on the drive shaft is slightly staggered, the tightness can be adjusted by itself to maintain a good fit.

5. The main supply of power plants, coal mines, printing and dyeing plants, boiler plants, etc., has been highly recognized by the industry.
