The calorimeter is based on the requirements of the People's Republic of China National Standard GB/T213 "Measurement of calorific value of coal", GB/T384 "Testing calorific value of petroleum products" and the national metrological verification regulations of the People's Republic of China JJG672 "Oxygen bomb calorimeter" The thermal capacity of this instrument is designed to be 12500～14000J/°C. It is suitable for determination of non-water-containing petroleum products (gasoline, jet fuel, diesel oil, fuel oil, etc.) as well as coal, coke, paraffin, garbage, leaves, etc. Determination of the calorific value of a substance. The measurement of the elastic calorific value is the amount of heat generated when a unit weight of the sample is burned under specified conditions when excess oxygen is present in the bomb. This is called the elastic calorific value (in J/g or kJ/kg).
Calorimeter performance characteristics:
1.Exclusive use of three barrels of circulating water system, can continuously test the sample 24 hours a day, the information is accurate and intuitive, automatic water injection, automatic water release, automatic mixing, automatic ignition, automatic printing results.
2. The whole process of automatic control, with sound prompts, failure to display a number of alarm functions; can automatically mark the calorimeter system energy equivalent (heat capacity), measuring heat, to avoid human error, accuracy and precision greatly improved.
3. Experimental automatic cooling correction, relaxed requirements on the ambient temperature, while improving the accuracy of the experiment, but also to ensure the stability of the long-term operation of the instrument.
4. The results of the experiment are clear at a glance. It is an ideal test equipment designed for the scientific research and military departments of enterprises and universities.
The heat capacity of the calorimeter is determined by burning a certain amount of standard benzoic acid in an oxygen bomb and measuring the temperature change of the calorimeter system caused by the heat generated by its combustion to determine the heat capacity of the calorimeter, that is, the temperature of the calorimeter system is increased. The amount of heat (J) required at 1°C is numerically equivalent to the calorimeter's heat capacity (J/°C).
