What Causes Clinkers in Coal Fired Boilers? Hunker

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.

Clinker (waste) - Wikipedia

Clinker is a general name given to waste from industrial processes, particularly those that involve smelting metals, welding, burning fossil fuels and use of a blacksmith's forge, which commonly causes a large buildup of clinker around the tuyere.Clinker often forms a loose, dark deposit consisting of waste materials such as coke, coal, slag, charcoal, and grit.

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.

Due to different formation temperatures of C 4 A 3 Ŝ and C 5 S 2 Ŝ, heat treatments of two cycles were used to maintain ternesite in the clinker. The first and second cycles were carried out at 1270°C and 1000–1200°C, respectively. With the use of one cycle, there was no ternesite formation in the clinker.

Thermodynamics of Clinker Formation

This reaction is also endothermic - but less so. As with the first reaction, the standard enthalpy change here can be calculated using the table provided. This time it's 115.08 kJ/mol (of CaCO 3) or 1.1498 MJ/kg.. Poor Martin was entirely unaware of data on the enthalpies of formation of the silicates (), and in 1925 the nature of the minerals in clinker was by no means settled - many believed ...

What Causes Clinkers in Coal Fired Boilers?

Clinkers, or slag, are made up of elements and minerals found in coal which are non-combustible. When burnt, they melt and fuse together, forming lumpy ashes. For as long as we have operated coal boilers, clinkers have been a recurring problem, occurring in small stoves used for heating a home right up to giant commercial/industrial boilers.
