Bethany Snoby and I have an article in American Coal Councils publication American Coal (issue 2, 2010) on “Valuation of Precombustion Coal Cleaning Facilities for Power Plants” which describes a model for calculating the financial value of tradeoffs between coal prep costs and combustion efficiency improvements. This helps unfamiliar users estimate the amount to spend on coal prep plants to get the improvements in electric plant efficiency and performance, and what level of cleaning to pursue for optimum results. Contact me if you want to see it.
could we read the report
