Calorific Value Testing Equipment Oxygen Bomb Calorimeter
(oxygen bomb calorimeter using bomb calorimeter test method, for calorific value testing.)
The instrument is designed and made as per national standards of People' s Republic of China GB/T213-2008 Test Method for Calorific Value of coal, GB/T384-1988 Test Method for Calorific Value of Petroleum Products and Calibration Regulation of People’s Republic of China JJG672-2001 Oxygen Bomb Calorimeter, as well as Shanghai enterprise standard Q/YXYY 10 XRY Series Oxygen Bomb Calorimeter.
The heat capacity of the instrument is 14400 J/K~14500 J/K, and it is suitable to determine calorific value of combustible materials such as petroleum products without water (gasoline, jet fuels, diesel oil and fuel oils, etc.), coal, coke and paraffin, etc.
1. This instrument adopts sealed oxygen bomb. The whole structure adopts stainless steel material. The strength is enough to resist the max pressure (60~70 atmospheric pressure) when the solid burning. And it can resist the bigger pressure when liquid fuel burning.
2. The inner water cylinder is composed of stainless steel sheet.The cross section is pyriform and the capacity is 3kg. The water cylinder is equipped with electric stirrer inside. It ensures the temperature in the water cylinder uniform.
3. The external water jacket is double layer container. It filled with water when doing determination.It make the water temperature in the cylinder uniform by water jacket stirrer and form the constant temperature environment meeting the requirements of test.
