Coal Blending and Process Redesign for Steam Generation Plant 12 1.5 Project Scope The scope of the project covers the deliverables outlined in the document. Coal blending model- An accurate coal blending model will be formulated with constraints and will form the basis for the coal blending .
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.
The coal handling system remained essentially unchanged; the original equipment since the middle 1950's from the rail dumper and reclaim though the belt systems. AES Cayuga's new coal blending ...
Coal blending is a practice that has been undertaken by many power stations to provide a consistent feedstock of fuel for power generation or to meet different requirements such as solving transportation problems, fuel cost, reducing slagging and SO x emission. 133, 134 In Coal Blending for Power Stations, Carpenter 135 listed the other reasons ...
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 200-ton surge bin and belt conveyors. A simple test was performed on the agglomerated coal fines to confirm the dedusting efficiency.

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.
Coal blending optimization of coal preparation production process is one of the most important segments in the schedule of coal preparation production, and the last link of product quality control in coal preparation plant. It can increase the diversity of prepared coal, .
