Assessment of Fly-Ash Erosion Potential of Indian Coals
Erosion is defined as a process by which material is removed from the layers of a surface impacted by a stream of abrasive particles. Fly-ash particles entrained in the flue gas from boiler furnaces in coal-fired power plants can cause serious erosive wear on steel surfaces along the flow path, thereby reducing the operational life of the mild-steel heat transfer plates that are used in the rotary regenerative heat exchangers. Moreover, in technical practice, erosion is often accompanied by a chemical attack. The variables which influence the wear process can be separated and studied independently.
