• 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.
