Coal blending for power stations, IEACR/81 IEA Clean Coal ...

Coal blending for power stations, IEACR/81. 1 July 1995. Anne Carpenter. Blending of coals of different types at pulverised coal-fired power stations is becoming increasingly common as electric utilities attempt to save costs, meet SO2 emission limits and improve the combustion behaviour of their coals. This report discusses the evaluation and prediction of the behaviour of blends of coals of different types and/or ranks in conventional pulverised coal-fired power stations.

Coal Blending Using the AllScan Onbelt Coal Analyser

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. Blending of coals is expected to grow over the next decade as electric utilities attempt to reduce cost, meet SO2 emission limits and improve combustion performance of their coals.
