Why the boiler grate burnout? How to repair it?

Following is the reason for boiler grate burnout:

1. The coal steam in the chain grate stoker is nonuniform, furnace with too high temperature, too many imperfect combustion coal accumulation at the end of the grate slag trap keeping on burning.

2. The dam-board doesn’t make regular ash discharge, the small size coal follows down and still burns in a fine ash bucket, which results in chain grate stoker framework deformation, or worse leads to burnout of chain grate¬†link.

3. When banking fire, the bottom of the travelling grate stoker loses cooling and causes the link and boiler grate bar damage.

Handling method, How to handle the problem?

1. Change work method bulldozed flat coal seam.

2. Dislagging regularly.

3. To improve banking fire technology
