Coal Blending Using the AllScan Onbelt Coal Analyser

Jun 01, 2015· AllScan Onbelt Coal Analyser Use in Blending In coal-fired power generation in particular, blending of coals is undertaken to reduce the cost of generation and increase availability of coal. Low-grade coals can be mixed with better grade coal without deterioration in thermal performance of the boiler thus reducing the cost of generation.
