Ash Furnace an overview ScienceDirect Topics
Pulverised coal-fired furnaces are usually classified according to the method of ash removal into molten-ash and dry-ash furnaces. In molten-ash furnaces, the boiler tubes in the lower part of the furnace are covered by a refractory to reduce heat extraction and to allow the combustion temperature to rise beyond the melting point of the ash.
