  • Avoiding Clinker Formation in Thermal Power Plant Boilers

    IntroductionCauses of Clinker FormationDealing with Clinker RemovalSummaryClinker formation is a serious problem in the boilers of thermal power plants which results in forced outage for very long duration and generation loss. The removal of clinkers from the water wall and hopper of boilers is very difficult because clinkers are very hard lumps due to presence of metals in them. Removal of clinkers from boiler is very difficult procedure which takes a long time and the cost involved is also very high. Pneumatic hSee more on brighthubengineering
  • 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.
