Clinker formation rotary kiln

Clinker formation is a serious problem in boilers of thermal power plants which results in forced outage and generation loss Removal of clinkers from the water wall is difficult thus requires pnmatic hammering Low quality coal having less gross calorific value, high mineral content, high ash content, and the overfiring of molten slag are causes of clinker formation
