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 overfiring of molten slag are causes of clinker formation.

Jun 13, 2016· reference: Avoiding Clinker Formation in Thermal Power Plant Boilers Clinker or slag is a fused mass of noncombustible residue (ash) from coal. All coal has some amount of ash content; bad coal has more ash, that''s all. Oxidation of the minerals ...
Dust generation in specific sections of cement plants (crushers, raw mill, coal mill, kiln, clinker cooler, cement mill) • Sulfur dioxide (SO 2) emissions arising from oxidation of sulfurcontaining compounds present in raw materials and fuel • Nitrogen oxide (NO x) emissions from the plants (in the range of 400–1300 mg/m 3) •
heating the rawmix to sintering temperature (up to 1450 °C) in a cement kiln; grinding the resulting clinker to make cement (see Cement mill). In the second stage, the rawmix is fed into the kiln and gradually heated by contact with the hot gases from combustion of the kiln fuel. Successive chemical reactions take place as the temperature of ...
Clinker often forms a loose, dark deposit consisting of waste materials such as coke, coal, slag, charcoal, and grit. Clinker often has a glassy look to it, usually because of the formation of molten silica compounds during processing. Clinker generally is much denser than coke, and, unlike coke, generally contains too little carbon to be of ...

Other contributors to clinker formation include failure to remove soot and other deposits, poorly pulverized coal, and improper burner adjustments that result in inefficient mixtures of air and fuel. A firebox that''s too small for the type of coal being burned coupled with infrequent ash removal also encourages clinker formation.
