XRY-1A Oxygen Bomb Calorimeter Coal Calorific Value Meter

Product description

XRY-1A oxygen bomb calorimeter is based on the People's Republic of China national standard GB/T 213 "Determination of calorific value of coal", GB/T 384 "Determination of calorific value of Petroleum products", the People's Republic of China National Metrological verification regulation JJG672 "Oxygen bomb calorimeter" and Shanghai enterprise standard Q/YXYY 10 Design and manufacture according to requirements of XRY-1A type oxygen bomb calorimeter.

The heat capacity of the instrument is 14400 ~ 14500J/K, suitable for the determination of non-aqueous petroleum products (gasoline, jet fuel, diesel and fuel oil, etc.) and coal, coke, paraffin and other combustible substances calorific value measurement by calorimeter oxygen bomb.

main technical characteristics

1, the instrument adopts self-sealing oxygen bomb, all the structure is made of stainless steel, strong enough to withstand the maximum pressure generated by solid combustion (60 ~ 70 atmospheric pressure), and can withstand the greater pressure generated by liquid fuel.

2. The inner water cylinder of this instrument is made of stainless steel sheet, the section is pear row, the water cylinder is loaded with 3000 grams of water, the water cylinder is provided with an electric stirrer, to ensure that the temperature of the water bath in the inner water cylinder is uniform.

3. The outer water jacket of the instrument is a double-layer container, which is filled with water during the experiment. The water temperature inside the cylinder is uniform through the water jacket agitator, which forms a constant temperature environment to meet the requirements of the test.
