Avoiding Clinker Formation in Thermal Power Plant Boilers
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 pneumatic hammering. Low quality coal having less gross calorific value high mineral content high ash content and the over-firing of molten slag are causes of clinker formation.
