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.
