What Causes Clinkers in Coal Fired Boilers? Hunker

Coal clinkers form when noncombustible elements contained in coal such as iron, calcium, silicon, aluminum and sodium interact with sulfur and carbon at high temperatures. These elements melt together with clays and alkalis to form a Limestoney slag that eventually hardens into clinkers.

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. The problem is compounded if there's no way to observe clinker ...
