The cost differential between the higher heating value coal and the lower heating value coal is 15/ton. The plant burns approximately 4 million tons of coal per annum. Blending with belt scales calculates a ratio of 67% for the higher heating value coal and 33% for the lower heating value coal.
AllScan Onbelt Coal Analyser Use in Blending. In coalfired power generation in particular, blending of coals is undertaken to reduce the cost of generation and increase availability of coal. Lowgrade coals can be mixed with better grade coal without deterioration in thermal performance of the boiler thus reducing the cost of generation.
Coal blending in power stations reduces the cost of generation and increases the availability of coal. Lowgrade coals can be mixed with better grade coal without deterioration in thermal performance of the boiler thus reducing the cost of generation, but there are many considerations before deciding to blend.
The agglomerated coal would be delivered to either of two locations, one being the stockpile, which meant handling by belt conveyor to the stacker/reclaimer, and the other being the bunker, which is serviced by a 200ton surge bin and belt conveyors. A simple test was performed on the agglomerated coal fines to confirm the dedusting efficiency.
