Coal Firing and Industrial Boiler Design—The Modern Approach

Coal is becoming increasingly more favorable as a fuel due to petroleum becoming too valuable to be used as one. The technology of firing coal has advanced tremendously as a result of new coal source discoveries and higher pressure and temperature steam generation. This paper defines the modern classifications of the different coals found in the United States and presents the respective design parameters for each classification. The varying design parameters in conjunction with the coal classifications are then related to modern industrial boiler design.
