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.

Avoiding Clinker Formation in Thermal Power Plant Boilers

In India the coal used for thermal power plants is often of low quality with low gross calorific value, high ash and minerals content, so the problems of clinker formation and deposition are evident in many plants. The best solution is to avoid the deposition of clinker is precaution. Blaming poor quality coal may prove harmful for the boiler.

What Causes Clinkers in Coal Fired Boilers? | Afri Coal

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. Boiler operators consider clinkers to be miserable stuff.

Frequently Asked QuestionsIntelligent Sootblowing, Water

A: The combustion of sulfur results in SO2 formation. As SO2 emissions is a function of coal sulfur content and the quantity of coal burnt, the only method of reducing SO2 production from a boiler cleaning perspective is an increase in boiler efficiency, which can be achieved by intelligent boiler cleaning.

Analytical model for erosion behaviour of impacted yash

In coalfired power stations, about 20% of the ash produced in the boilers is deposited on the boiler walls, economisers, airheaters and superheater tubes. This deposited ash is subsequently discharged as slag and clinker during the sootblowing process. The rest of the ash is entrained in the stream of ue gas leaving the boiler.
