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.For the pulverised coal fired boilers (A-D) about 80–90% of total mercury, released to the atmosphere and rest portion remained associated with fly ash. Mercury concentration in fly ash was higher than that in bottom ash. Bottom ash and mill reject contained only …
