Oxygen Bomb Calorimeter
The bomb calorimeter is a widely used device for measuring the heat of combustion or calorific value of a material. With this apparatus a test specimen of specified mass is burned under standardised conditions. The heat of combustion determined under these conditions is calculated on the basis of the measured temperature rise while taking account of heat loss.
The combustion process is initiated inside an atmosphere of oxygen in a constant volume container, the bomb, which is a vessel built to withstand high pressures. It is immersed in a stirred water bath, and the whole device is the calorimeter vessel. The calorimeter vessel is also immersed in an outer water bath. The water temperature in the calorimeter vessel and that of the outer bath are both monitored.
The Oxygen Bomb Calorimeter is a versatile instrument and can be used to measure the heat generated from several applications and has been designed to conform to current ASTM, ISO, EN, BS and DIN standards.
- Building materials (EN ISO 1716)
- Coal, coke (ASTM D5865)
- Fuel (ASTM D240: gasoline, kerosene, fuel oil, Nos. 1D and 2D diesel fuel and Nos. 0GT,1GT, and 2GT gas turbines fuels and ISO 1928)
- Fuel derived from waste material (ASTM E711)
- Hydrocarbon fuels (ASTM D4809)
- Food, supplements, crops
- Waste and refuse
The Oxygen Bomb Calorimeter consists of:
- Measuring cell
- Decomposition vessel
- Oxygen filling station
- Consumables for calibrations and installation
