2021年2月1日 The coal has higher ash content usually employed for power generation under Indian climatic conditions. The composition of ash (in wt% dry basis) is assumed as Al 2 O 3: 13.13, SiO 2: 32.68 and Fe 2 O 3: 4.72. The presence of higher ash content in coal may result in erosion related problems, which needs to be addressed carefully. In the
