Abstract
A gas calorimeter and method of measuring the calorific value of fuel gases in which a fixed volume of gas to be measured is burned in a controlled environment. The temperature increase of the air in the environment caused by the burning is used to determine the calorific value of the gas. The gas to be measured is intermittently supplied to the controlled environment using a base plate which has portions defining a plurality of dispersion holes in a distributed manner so that a greater number of the plurality of dispersion holes are in and around the periphery of the base plate than are in and toward the center of the base plate.
