oe Smith from " Emerging Technology Center" visits our Demonstration Boiler facility and says to you " I am impressed with your research programs here and you have an excellent Demonstration Boiler but when you burn coal water slurry in this boiler don't you lose a lot heat in evaporating the 40 - 50% water that you add in making coal water slurry ?". What would be your answer to this question? Calculate the lower heating value of the Brookeville Seam coal with the analysis given below with 10, 20, 30, 40, and 50% moisture contents . Comment on the percentage of the heat loss based on the gross or high heating value of the fuel in using the coal with these moisture levels.
