●Application field of coal coke automatic calorimeter

Applicable to electric power, coal, environmental protection, energy saving, petrochemical, metallurgy, cement, paper, food, geological prospecting, scientific research institutions and other industries to measure coal, coke, petroleum, food, cement raw meal, biofuel and other solid or liquid combustibles of calorific value.

●Technical features of coal coke automatic calorimeter

1. Fast speed: unique three-head thread and corrosion-resistant oxygen bomb (combustible biomass), short test time. Conventional method: ≤16min; rapid method: ≤10min.

2. Save worry and effort: high degree of automation, more convenient operation. It can automatically and accurately control the water volume of the inner cylinder; automatically adjust and track the system temperature; less manual operation content, reduce human error and labor intensity, and improve work efficiency.

3. More accurate:

(1) Quantitative water cups are used to ensure the accuracy and stability of the water volume in the inner cylinder and to ensure the consistency of each measurement result.

(2) Built-in automatic refrigeration cycle control device. Different temperature control methods of inner and outer cylinders can be selected according to needs, and the data is more accurate.

(3) Built-in filtering system to prevent system blockage, and the stability of detection data is good.

(4) The heat capacity of the instrument is stable for a long time, and the change of heat capacity is ≤0.2%.

4. More convenient functions:

(1) Experiment login authority management, automatic recording of the experiment process, and traceability.

(2) Automatic transmission of sample code and weight information; backup and upload of test results; tamper-proof experimental data, suitable for fuel control systems.

(3) Reserved standard interface: support network upload data, etc.

(4) The software system is powerful and has self-diagnosis function, which is convenient for maintenance.
