Fuels Higher and Lower Calorific Values
Higher and lower calorific values (=heating values) for some common fuels coke, oil, wood, hydrogen and others. The given values are for fuels with the given density. The variation in quality may give heating values within a range 5 10% higher and lower than the given value. Also the solid fuels will have a similar quality variation for the different classes of fuel.
