Bomb Calorimeter ASTM D240 Calorific Value Measurement Bomb Calorimeter by Bomb Method ASTM D5865

Oxygen bomb calorimeter is an instrument specifically designed to accurately measure the heat of combustion of substances.
From the appearance, it mainly has a relatively sturdy oxygen bomb. This oxygen bomb is like a specially designed small container, which is the core part of the entire instrument. Its material is very sturdy and can withstand high pressure, as high-pressure oxygen needs to be filled inside during the measurement process. The interior of the oxygen bomb is where the tested sample and ignition wire are placed, and the sample burns in this closed space filled with oxygen.

The Bomb Calorimeter is designed and made according to GB/T213-2008 Method for the determination of the calorific value of coal, GB/T384-1988 Method for the determination of the heat value of petroleum products and Calibration and Inspection Regulation of People’s Republic of China JJG672-2001 Oxygen Bomb Calorimeter, as well as the Shanghai Enterprise Standard Q/YXYY 10 GDY-1 Oxygen Bomb Calorimeter.
The Bomb Calorimeter adopts high precision temperature sensor and high-power A/D converter, and uses single chip microprocessor to form an intelligent temperature data collection and transfer system. It uses microcomputer to form an automatic, convenient, rapid, and intelligent instrument. If the user operates the instrument carefully and input all kinds of parameters correctly, the desired measurement data will be getted. The instrument can be widely used to determine the calorific value of materials such as coal, oil, coke, paraffin and other combustible materials etc. It is an ideal option of the thermoelectricity, metallurgical, cement, chemical industries, scientific research institutes, college and universities.

Oxygen Bomb Calorimeter ASTM D5865
Based on the combustion reaction, heat is generated to raise the temperature of the surrounding medium (usually water). When measuring, place the accurately weighed sample in a small crucible or other suitable container inside an oxygen bomb, and connect the ignition wire. Then seal the oxygen bomb and fill it with sufficient oxygen. Then place the oxygen bomb into a container containing a certain amount of water, which has good insulation properties and can reduce heat loss to the surrounding environment.
