Description

Summary

    The instrument is designed and made as per the National Standard of People’s Republic of China GB/T213 “Test Methods for Calorific Value of coal”, GB/T384 “Test Methods for Calorific Value of Petroleum Products” and Calibration Regulation of People’s Republic of China JJG672 “Oxygen Bomb Calorimeter”, as well as Company Standard of Shanghai Q/YXYY 10 “XRY-1 Series Oxygen Bomb Calorimeter”.
    The heat capacity of the instrument is 14400~14500 J/K, and it is suitable for the determination of water-free oil products (gasoline, jet fuel, diesel oil and fuel oil, etc.) and combustible material such as coal, coke, paraffin wax content determination of calorific value.
 
I. Main technical features
1. The instrument uses a self-sealed oxygen bomb, all the structure of the use of stainless steel, the strength is sufficient to withstand the maximum pressure generated by solid combustion (70 ~ 60 ATM), and can withstand the pressure of liquid fuel generated by the greater pressure.
2. The inner tube of the instrument is made by stainless steel sheet, a section of pears, put the barrel of water was 3000 grams, water cylinder with electric blender, to ensure that the inner tube water bath temperature uniformity.
3. The instrument of the external water jacket is a double container and experiment when filled with water, through the water jacket mixer to the cylinder in uniform temperature, formed to meet the test requirements of the constant temperature environment.
