Working Principle

The working principle of the bomb calorimeter is to measure the heat released when the fuel is completely burned under the condition of sufficient oxygen. The sample is placed into an oxygen bomb, a sealed container, which is filled with oxygen and then ignited by an electric ignition device. The heat released during combustion is transferred through the walls of the oxygen bomb to the surrounding water, thereby increasing the water temperature. The calorific value of the fuel is calculated by measuring the change in water temperature and combining it with the specific heat capacity of water. The instrument accurately calculates the calorific value of the sample through high-precision water measurement and temperature change monitoring.
