Compact automatic oxygen bomb calorimeter

Scope of application

CBC-900 series small oxygen bomb automatic calorimeter adopts a revolutionary three-dimensional isothermal structure design. The inner cylinder is surrounded by water three-dimensionally, which completely eliminates the evaporation of water during the heat measurement process; the professional cold water station is used to accurately control the temperature of the outer cylinder water. The influence of environmental temperature changes, the repeatability of results, long-term stability, and automation have reached the international leading level.

This product can be used in electric power, coal, metallurgy, petrochemical, environmental protection, building materials, papermaking, geological prospecting, scientific research institutions and other industry sectors to measure the calorific value of combustibles such as coal, coke, petroleum and cement black raw materials. It is especially suitable for measuring accuracy requirements. Used by power plants, coal quality inspection departments, large coal enterprises and scientific research units with high sample volume.

Technical characteristics

• Revolutionary representative of the structural design of the calorimeter, the 360-degree full coverage structure of the inner cylinder of water completely solves the problem of poor long-term stability of the traditional calorimeter.
• The standard measuring method time is less than 9 minutes, which is twice as efficient as the traditional calorimeter.
• With automatic oxygenation function, oxygenation automatic timing and automatic stop.
• With safety protection device, the oxygen pressure exceeds 3.2 MPa and automatically deflates and returns to safe air pressure.
• Equipped with an independent cold water station and a high-precision temperature control device to ensure that the temperature control error of the outer barrel water is within ±0.005℃.
• Adapt to the requirements of high-intensity experiments, and can work continuously without interruption.
• The cotton thread ignition technology is used to solve the problem of poor contact of the ignition wire and easy entry of the ignition wire into the instrument, improve the measurement accuracy and reduce the failure rate.
• It can directly measure the calorific value of coal gangue and coal slime without adding any combustion aid.
