What Are the Common Faults of Flake Grates?
The common faults of flake grates mainly involve running jams, coal and air leakage, damaged grate bars, and drive abnormalities. The specific types and core causes are as follows:
-
Severe coal and air leakage: Excessively large gaps between the grate bars or worn sealing strips cause coal leakage and uneven ventilation.
-
Drive-system faults: Wear on the driving sprocket, improper chain tensioning, or damage to the main-shaft bearing.
-
Ash accumulation and blockage in the wind box: Ash and slag build up and clog the wind box, affecting primary-air distribution.
