TABLE 22
HEAT CAPACITY AND CALORIFIC INTENSITY CURVES

Comparison of five gases arranged in the order of their calorific intensity
giving their thermal value, thermal value of combustible mixture, the heat
contained in their products of combustion, the volume of the air supply, the
combustible mixture and the products of complete combustion.
