Lab Coal Measuring & Analysing Instruments Oxygen Bomb Calorimeter
The Oxygen Bomb Calorimeter is designed and made according to GB/T213-2008 Method for the determination of the calorific value of coal, GB/T384-1988 Method for the determination of the heat value of petroleum products and Calibration and Inspection Regulation of People's Republic of China JJG672-2001 Oxygen Bomb Calorimeter, as well as the Shanghai Enterprise Standard Q/YXYY 10 GDY-1 Oxygen Bomb Calorimeter.
The Oxygen Bomb Calorimeter adopts high precision temperature sensor and high-power A/D converter, and uses single chip microprocessor to form an intelligent temperature data collection and transfer system. It uses microcomputer to form an automatic, convenient, rapid, and intelligent instrument. If the user operates the instrument carefully and input all kinds of parameters correctly, the desired measurement data will be getted. The instrument can be widely used to determine the calorific value of materials such as coal, oil, coke, paraffin and other combustible materials etc. It is an ideal option of the thermoelectricity, metallurgical, cement, chemical industries, scientific research institutes, college and universities.

ASTM D240 Standard Test Method for Heat of Combustion of Liquid Hydrocarbon Fuels by Bomb Calorimeter, which is suitable for testing the gross calorific value and net calorific value of the petroleum products without water (gasoline, jet fuel, diesel oil and heavy oil, coke, coal gangue, brick, petroleum and other solids and liquid. It is widely applied in the areas of coal, metallurgy, petrochemical, quality inspection, environmental protection, steel, food, electricity, feed, paper, chemical, cement and brick,etc.
Normal Problem and Solution:
No. |
Problem |
Cause |
Solution |
1 |
Indication light is off. |
1.No power supply.
2.The fuse is damaged. |
1.Connect the power supply
2.Replace the fuse. |
2 |
Can not be ignited. |
1.The ignition electric pole is poor connected with oxygen bomb.
2.The ignition wire is short circuited. |
1.Make sure the electric pole and oxygen bomb well connected.
2.Install the ignition wire again. |
3 |
Stirrer doesn't work |
1.The stirring motor is blocked.
2.The stirring motor wire is disconnected. |
1.Get rid of the blocks.
2.Connect the wire again. |
4 |
Temperature doesn't decrease |
1.Water temperature in outer bucket is much lower than ambient temperature.
2.The sample mass is too less. |
1.Make determination again after regulating the outer bucket temperature.
2. 2.Use more sample to rise the
temperature 2 K~3K. |
5 |
Clock stops |
1. the clock has no power |
1.Replace battery
2.Manually input time to continue determination. |
(1) The main unit of calorimeter is the important part of the calorimeter. It is mainly used to form a constant temperature system, and to ensure it can accurately show the temperature rising curve of the sample under the constant temperature condition during the procedure of ignition and stirring, so that to calculate the heat value of sample.
(2) Bomb head holder, oxygen filling device, and discharging valve: be used to prepare the sample, install the ignition wire, fill oxygen into the bomb and exhaust oxygen after determination.
(3) Microcomputer(single-chip): one of the most important parts of the instrument. It can automatically control the determination procedure, record and save the test data.
(4) Printer: print out the test data.
