Automatic Bomb Calorimeter

BD-700 Automatic Bomb Calorimeter

The BD-700 series automatic calorimeter has reached the international advanced level in terms of accuracy, automation level and appearance. Appraised by the National Coal Inspection Center, the thermal capacity of BD-700 has a three-month fluctuation of ≤0.13%, which is a significant improvement over the domestic advanced level of 0.20%. The high-precision measurement method for water in the inner cylinder developed by automation does not require electrolytes to be added to the water, which is scientific The water temperature control strategy ensures that the test results are accurate and fast. It has also invested heavily in appearance design and mold molding, and its appearance is also comparable to similar international products such as IKA and Parr.

Application field

This product can be used in electric power, coal, metallurgy, petrochemical, environmental protection, building materials, papermaking, geological prospecting, scientific research institutions and other industries 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.

It is used by large-scale mining bureaus, power plants, coal quality inspection departments and scientific research units with high sample volume.

Technical characteristics

1. Equipped with an independent cold water station, the host has a special temperature control device to ensure a constant water temperature in the outer barrel, and the control accuracy of the outer barrel water temperature reaches 0.05°C. The temperature of the outer barrel is automatically controlled with the change of the ambient temperature, which realizes the joint control without manual adjustment of the cold water station.
2. Automatic filling and drainage technology: no need to move the inner cylinder, automatic water intake and drainage, reducing the labor intensity of the operator.
3. The measurement range is wide, not only can measure coal, but also can directly measure the calorific value of various combustibles such as briquette, coal slime, coal gangue, sludge, etc., with a calorific value as low as 300 cal/g without adding any combustion aid.
4. The sample can be measured continuously and continuously.
5. Accurate prediction technology of H content to ensure the calculation accuracy of low calorific value.
6. Realize the tracking and joint control of the temperature of the cold water station and the environment, without manually setting the temperature of the cold water station, and the stability is further improved
7. Peripheral isothermal technology
8. Cotton thread ignition technology
9. Fast ash determination technology
10. Adopt streamlined design, molded case, high-precision cold water station;
