Automatic industrial analyzer (two-body)
The scope of application of fully automatic industrial analyzers:
It is suitable for electric power, coal, metallurgy, petrochemical, environmental protection, cement, papermaking, geological exploration, scientific research institutions and other industries to measure the moisture, ash and volatile matter of coal, coke or other organic matter and calculate its fixed carbon and calorific value. It can also analyze fly ash, ash, coke and carbon content.
Standard: GB/T212-2008 "Method for determination of calorific value of coal".
The main features of a fully automated industrial analyzer are:
GB/T 483-2008 "General Regulations on Test Methods for Coal Analysis", GB/T 212-2008 "Industrial Analysis Methods for Coal", and the American ASTM D5142 standard instrument have two test parts, part B is dedicated to testing volatile matter, and part A tests moisture and ash. The two parts are controlled by a computer and can work either simultaneously or separately.
The advantages of this approach are:
High efficiency: Rapid method: 19 samples of moisture, ash, volatile matter ≤ 120min Classic method: 19 samples of moisture (drying test), ash (slow ash + drying test) 260min, volatile matter 120min (part B) moisture, ash, volatile matter three indicators can be determined in any combination or separately.
Adopt imported integral furnace, fast heating speed, energy saving and short test time. Adopt imported electronic balance and imported stepping motor to ensure stable test performance.
Other advantages:
① Applicable to all coal types, there is a nitrogen device, and the moisture test can be used by nitrogen drying method; a special high temperature furnace tests volatile matter, completely
The process of volatile matter testing in the national standard is simulated. The national standard GB/T212-2008 stipulates high temperature furnace and ash test for volatile matter testing
The furnace structure is different.
② Volatile test crucible is dedicated, and the crucible volume, heat transfer speed, and pressure are all the same as the national standard crucible, ensuring that the volatile test results fully meet the requirements of GB/T212-2008, and are completely consistent with the classical test results, overcoming the previous industrial analyzer volatile test results cannot fully meet the national standard defects.
③ Two parts work at the same time, moisture, ash and volatile matter are tested at the same time. There is no need to replace the crucible or uncover the lid in the middle of the process. After the coal sample is released, it can be unattended in time and quickly, and the results of moisture, ash, volatile matter and fixed carbon can be automatically obtained. Overcome the assembly line
The working method cannot be tested simultaneously, and all industrial analysis results cannot be obtained in a timely manner. The crucible needs to be replaced or covered in the middle of the process.
④ High reliability, without a crucible plane moving device such as a "robot", there will be no phenomenon of dropping or breaking the crucible during transmission.
⑤ Two sample feeding rods are used for volatile matter testing, and two samples are sent to the high temperature furnace at 900 ° C at the same time, which accelerates the volatile matter testing speed. The moisture, ash and volatile matter classic method tests of 19 samples can be completed within 120 minutes, and the fixed carbon, calorific value and hydrogen content can be calculated.
There are a variety of test methods for users to set at will, including the national standard arbitration method, the fast method, and the user can also set the method at will.
The use of thermal balance, thermogravimetric analysis technology, and the use of empty crucible correction in the same atmosphere environment ensure accurate weighing, and solve the technical problems of pipeline working mode, empty crucible correction is invalid, and the crucible temperatures are different one after another, and the weighing is inaccurate.
With a silent air pump, experiments can be carried out without oxygen or nitrogen, which solves the problem of high noise and physical and mental health caused by the use of compressor pumping.
The circular well-shaped high temperature furnace has a more uniform and stable temperature distribution, which solves the technical problem of uneven and unstable temperature caused by frequent opening of the furnace door in the assembly line.
Ceramic fiber high temperature furnace has small heat capacity, fast heating and cooling speed, short continuous testing time for multiple batches, good thermal insulation effect and significant energy saving.
Technical parameters of a fully automatic industrial analyzer:

The American ASTM D5142 standard.
Number of single disc samples: 19 (19 samples can be tested at one time)
Maximum furnace temperature: 1000 ℃
Weight: Part A 95 kg Part B 90 kg
Temperature control accuracy: 5 ℃
Power: A + B two parts 9kW
Test accuracy: in line with GB/T212-2008 standard requirements

Gas requirements (or without a gas source): Oxygen: purity 99.5%, pressure 0.1Mpa after decompression, nitrogen: purity 99.5%, pressure 0.1Mpa after decompression, pressure reducer: high-end 0~ 25Mpa low-end 0~ 0.4Mpa
Sample quality: moisture, ash sample 0.6~ 1.1g (quality adjustable); volatile matter 0.9~ 1.1g
Regarding the testing time
GB/T 212-2008 "Industrial Analysis Methods of Coal" 4.1.3.2 requirements for the determination of ash arbitration method are: "Send the ash dish into the constant temperature zone of the muffle furnace with a furnace temperature not exceeding 100 ° C, close the furnace door and leave a gap of about 15mm in the furnace door. Slowly raise the furnace temperature to 500 ° C within a time of not less than 30 minutes, and keep it here for 30 minutes. Continue to heat up to (81510) ° C, and burn at this temperature for 1h." It can be seen that the test results must meet the requirements of the arbitration law, and the test time cannot be less than 120min; just because the ash test must be heated from below 100 ° C, the ash test cannot be carried out in an assembly line operation, and the same furnace cannot do one sample at a time. The batch test mode of this instrument is more efficient. The instrument has been tested on more than 20 national standard coal samples, and the results are accurate; compared with the national standard method, the instrument test results are completely consistent with the GB/T212-2001 standard test results.
