Coal Blending Strategies Reduce Costs and .

The next article will focus on coal-blending strategies at a power plant. A coal mine located in West ia uses an on-line analyzer to monitor the prep plant production stream. Based on data from the analyzer, coal is sorted by adjustable parameters, such as ash. Any coal with an ash percentage less than 16% is sent directly to the stockpiles; the raw coal greater than 16% is sent to the ...
