Jan 10, 2010· Moisture in coal varies from the point where it is received to the point where it enters the boiler. The variation in the moisture affects the reported heating value and analysis. The laboratory analysis is required to be corrected to the actual moisture content in the field. Methods for applying these corrections are explained here.

For typical bituminous coal with 10% M and 25% Volatile Matter, the differences between gross and net calorific values are approximately as follows: 260 kcal/kg 1.09 MJ/kg 470 Btu/lb Power Generation 1 MWh = 3600 MJ 1 MW = 1 MJ/s 1 MW (thermal power) [MWth] = approx 1000 kg steam/hour 1 MW (electrical power) [MWe] = approx MW(thermal power) 3
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
