Mahler bomb calorimeter enables to measure the heat of combustion of a lot of solid and liquid substances. The heat
resulting from the combustion reaction of the fuel under examination is absorbed by a known mass of water where temperature rise is checked. The bomb consists of a cylindrical vessel closed by a screw cover with two electrodes connected with an external circuit. The fuel whose heat value must be measured is poured into a crucible available inside the bomb. This bomb, connected with a cylinder of oxygen, is immersed into a calorimeter full of water, with stirrer and thermometer. When some current crosses the circuit, combustion starts; then heat value results from the measurement of the consequent rise of water temperature in the calorimeter.
