It is a constant-volume type calorimeter that measures the heat of a particular reaction or measures the calorific value of the fuels.
An apparatus primarily used for measuring heats of combustion. The reaction takes place in a closed space known as the calorimeter proper, in controlled thermal contact with its surroundings, the jacket, at constant temperature.
Bomb Calorimeter was used to measure the cross calorific value of the solid and liquid samples.
