Automatic Oxygen Bomb Calorimeter – GAOTek

Description Overview The automatic calorimeter is suitable for measuring the power, coal, metallurgy, petrochemical, quality inspection, environmental protection cement, papermaking, geological exploration, scientific research institutes and other industrial sectors. Measures the calorific value of coal, coke, petroleum, cement, bricks, and other solid or liquid fuels, in compliance with the coal calorific value calculation standard.   Features The user only needs to install the oxygen bomb when the user operates, and the remaining electronic balance is used to read the sample weight, oxygen, oxygen bomb, oxygen bomb, quantitative inner cylinder water, ignition, completion test, oxygen bomb deflation, experiment Results statistics and other processes can be fully automated. Automatically adjust the temperature difference between the inner and outer cylinders to ensure that the inner cylinder is about 1K higher than the outer cylinder temperature at the end point, which fully meets the requirements of the national standard 8.2.4, and the test results are stable for a long time. It can carry out experiments for more than 72 hours, which solves the technical problem that the calorimeter without cooling device needs to suspend the experiment due to the increase of the outer cylinder water temperature (overshoot). Imported mechanical parts, automatic oxygenation, automatic deflation, automatic lifting oxygen bombs and other sports. The compressor cooling and special heating device are adopted to realize the automatic control of the water temperature of the outer cylinder, and the temperature control accuracy meets the requirements of the national standard 7.1.4 (±0.1K).   Technical Specification Heat capacity About 50000J     Oxygen bomb working pressure (oxygen charging) 2.8-3.0mpa, maximum 3.2Mpa Pressure test (water pressure): 20.0Mpa Volume: 300ml Mass: 2.5kg Boundary dimension: φ 86mm × 181mm Capacity of external water cylinder About 45L Capacity of the inner water cylinder About 2.1L Ignition voltage AC24V Ignition method Fusible cotton wire ignition Temperature resolution 0.0001 ℃ Temperature measurement range 0-40 ℃   ASTM D5865, ASTM D240, ASTM D4809, Measurement accuracy shall meet ASTM E711, ASTM D5468, AS 1038.5， the national standard BS EN 15400, BIS1350, ISO 1928,   ISO 9831, ISO18125, GB/T 213, GB/T 30727 Test time ≤ 15 minutes Power supply AC220V~±10%，50Hz Power of the whole machine Less than 30W in normal state and less than 300W in ignition state Operating environment Room temperature 5-35 ℃, humidity < 80%
