What Causes Clinkers in Coal Fired Boilers? | Hunker

Jul 17, 2017 · Clinkers form as a result of interaction among coal quality, boiler design and boiler operation. Coal boilers draw their combustion air from the bottom, up through the combustion grate. Lots of large clinkers on the combustion grate can hinder air passage, increase operation and maintenance costs and even force shutdowns of the boiler for
