Related: Industrial analyzers; Automatic industrial analyzer; Fully automatic industrial analyzer; Coal Industry Analyzer
Scope of application of fully automatic industrial analyzer:

Suitable for industries such as electricity, coal, metallurgy, petrochemicals, environmental protection, cement, papermaking, geological exploration, and research institutions to determine the moisture, ash content, and volatile matter of coal, coke, or other organic matter, and calculate their fixed carbon and calorific value. It can also analyze fly ash, ash residue, coke, and carbon content.
Adopting standard: GB/T212-2008 "Method for determination of calorific value of coal".
The main features of fully automatic industrial analyzers are:
GB/T483-2008 "General Provisions for Coal Analysis Test Methods", GB/T212-2008 "Industrial Analysis Methods for Coal", and the American ASTM D5142 standard instrument have two testing parts, Part B specifically tests volatile matter, and Part A tests moisture and ash content. Two parts are controlled by a computer, which can work simultaneously or independently.
The advantages of this approach are:
High efficiency: Rapid method: Moisture, ash, and volatile matter of 19 samples ≤ 120 minutes. Classic method: Moisture (dryness test) and ash (slow ash+dryness test) of 19 samples are tested for 260 minutes, and volatile matter is tested for 120 minutes (Part B). The three indicators of moisture, ash, and volatile matter can be measured in any combination or separately.
Adopting imported integral furnace, with fast heating speed, energy saving, and short testing time. We use imported electronic scales and stepper motors to ensure stable testing performance.
Other advantages:
① Suitable for all types of coal, equipped with a nitrogen device, and moisture testing can be conducted using the nitrogen drying method; Specialized high-temperature furnace tests for volatile matter, completely
Simulated the process of volatile matter testing according to the national standard GB/T212-2008, which specifies the high-temperature furnace for volatile matter testing and the high temperature for ash content testing
The furnace structure is different.
② The volatile matter testing crucible is specialized, with the same volume, heat transfer rate, and pressure as the national standard crucible, ensuring that the volatile matter testing results fully comply with the requirements of GB/T212-2008 and are completely consistent with classical testing experimental results, overcoming the shortcomings of previous industrial analyzer volatile matter testing results that cannot fully comply with national standards.
③ Two parts work simultaneously, testing moisture, ash content, and volatile matter simultaneously. There is no need to replace the crucible or remove the cover during the process. After placing the coal sample, it can be unmanned and quickly obtained automatically for moisture, ash content, volatile matter, and fixed carbon. Overcoming the assembly line
The working mode cannot be tested simultaneously, and all industrial analysis results cannot be obtained in a timely manner. Defects that require replacement of crucibles or removal of covers during the process.
④ High reliability, without "mechanical arm" or other crucible plane moving devices, there will be no phenomenon of dropping or damaging the crucible during transportation.
⑤ Two sample rods are used for volatile matter testing, and two samples are sent to a 900 ℃ high-temperature furnace at the same time, which accelerates the speed of volatile matter testing. The moisture, ash content, and volatile matter of 19 samples can be tested using the classical method within 120 minutes, and the fixed carbon, calorific value, and hydrogen element content can be calculated.
⑥ There are multiple testing methods available for users to set freely, including the national arbitration method, the fast method, and the method that can be set by users at will.
⑦ By using a thermal balance and thermogravimetric analysis technology, and calibrating with an empty crucible in the same atmosphere environment, accurate weighing is ensured, solving the technical problem of ineffective calibration of empty crucibles in assembly line operation, different temperatures of crucibles produced successively, and inaccurate weighing.
⑧ Equipped with a silent air pump, experiments can be conducted without the need for oxygen or nitrogen, solving the problem of high noise and negative impact on physical and mental health caused by using a compressor to pump air.
⑨ The circular well shaped high-temperature furnace has a more uniform and stable temperature distribution, solving the technical problem of uneven and unstable furnace temperature caused by frequent opening of the furnace door in the assembly line working mode.
⑩ Ceramic fiber high-temperature furnace has a small heat capacity, fast heating and cooling speed, short continuous testing time for multiple batches, good insulation effect, and significant energy saving.

ASTM D5142 standard in the United States.
Number of samples per disk: 19 (19 samples can be tested at once)
◆ Maximum furnace temperature: 1000 ℃

◆ Sample quality: Moisture and ash content sample 0.6-1.1g (adjustable mass); Volatile matter 0.9-1.1g
Regarding the issue of testing time
The requirement for determining ash content by arbitration method in Article 4.1.3.2 of GB/T212-2008 "Industrial Analysis Methods for Coal" is:
Feed the furnace into the constant temperature zone of a muffle furnace with a temperature not exceeding 100 ℃, close the furnace door and leave a gap of about 15mm on the door. In many
Slowly raise the furnace temperature to 500 ℃ within 30 minutes and maintain it there for 30 minutes. Continue to heat up to (815 ± 10) ℃,
And burn it at this temperature for 1 hour. "From this, it can be seen that the test results must comply with the requirements of the arbitration law, and the testing time cannot be less than 120 minutes
Due to the fact that ash testing must start heating from below 100 ℃, it is not possible to use assembly line operation for ash testing
One stove cannot make one sample after another. The batch testing mode of this instrument is more efficient. This instrument has undergone over twenty tests
The testing of national standard coal samples yielded accurate and error free results; Compared with the national standard method, the instrument test results are completely consistent with the GB/T212-2001 standard test results.
