GDY-1A Laboratory Calorimeter For Fuel,Gasoline,Coal
- The instrument is designed and made as per the National Standard of
People’s Republic of ChinaGB/T213-2008 Test Method for Calorific Value of coal,GB/T384-1988 Test Method for Calorific Value of Petroleum Productsand Calibration Regulation of People’s Republic of ChinaJJG672-2001 Oxygen Bomb Calorimeter, as well as Enterprise Standard ofGDY Series Oxygen Bomb Calorimeter.
- The heat capacity of the instrument is14400 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.
Main Technical Features
- 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.
- 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.
- 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.
