Abstract
The heat of combustion K.sub.1 of a gas is determined by burning the gas in air in a chamber and cooling the combustion products with air to a final temperature equal to the air and gas input temperature. With mass flowmeters, the gas flowrate W.sub.1, the cooling air flow rate W.sub.3, a T.sub.2 temperature sensor, and a sensor for the cooling air input temperature T.sub.3 are employed with a computer to derive K.sub.1 as follows: ##EQU1## where K.sub.3 is the specific heat of the cooling air. Alternatively an outlet temperature T.sub.1 may be substituted for T.sub.2.
