Summary

  The instrument is designed and made as per the National Standard of People’s Republic of China GB/T213-2008 and ASTM D240 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 Enterprise Standard of Shanghai Q/YXYY 10 XRY Series Oxygen Bomb Calorimeter.

  The heat capacity of the instrument is 14000 J/K～15000 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.

I. Main technical features

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.
