1Scope of application:

This instrument is suitable forMoisture, ash, and volatile matter detection of coal, coke, solid biomass fuels, solid/hazardous waste, and calculation of their fixed carbon and calorific value.

IImeet the standard：

GB/212-2008 "Industrial Analysis Methods for Coal"

GB/T30732-2014 "Industrial analysis methods for coal - Instrumental methods"

ASTM-D5142-2009 "Industrial Analysis Method for Coal and Coke Analysis Samples - Instrumental Method"

ISO 1171-2010 "Solid mineral fuels - Determination of ash content"

threeProductfeature:

1. Suitable for all types of coal, coke, and ores, using a specialized high-temperature furnace to test volatile matter, fully simulating the national standard testing process for volatile matter.

2. The test crucible is specialized, with the same volume, heat transfer rate, and pressure as the national standard crucible. The volatile matter test results fully comply with the requirements of GB/T212-2008 and are completely consistent with the classical test experimental results, overcoming previous limitationsIndustrial analyzerThe volatile matter test results do not fully comply with the national standard for defects.

3. Ash content and volatile matter are tested simultaneously in different furnace bodies, without the need to replace the crucible or remove the cover during the process. After placing the coal sample, the results of moisture content, ash content, volatile matter, and fixed carbon can be obtained quickly and automatically without human supervision. Overcoming the defects of the assembly line working mode that cannot test simultaneously, cannot obtain all industrial analysis results in a timely manner, and requires the replacement of crucibles or uncovering during the process.

4. High performance, without mechanical arms or other crucible plane moving devices, there will be no phenomenon of dropping or damaging the crucible during transportation.

5Four sample rods are used for volatile matter and ash content testing, and four samples are sent to high temperature furnaces at 900 ℃ or 850 ℃ at the same time, which accelerates the speed of volatile matter and ash content testing.

6. There are two testing methods available for users to set freely, including the national arbitration method and the fast method, which can also be set by users at will.Quick Method 24Complete the moisture and ash content of the sample in 90 minutes; Volatile matter is strictly sampled every 7 minutes according to the national standard; National Arbitration Law 24The sample's moisture and ash content will be completed in 150 minutes. The three indicators of moisture, volatile matter, and ash content can be combined and measured separately to meet the time requirements of different customers

7. Thermobalance, thermogravimetric analysis technology, calibrated with an empty crucible in the same atmosphere environment to achieve accurate weighing, solves the technical problem of ineffective calibration of empty crucibles in assembly line operation, different temperatures of the crucibles that come out successively, and inaccurate weighing.

8. Experiments can be conducted without the need for nitrogen, using compressor pumping or oxygen ash combustion assistance methods.

9. The circular 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. 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.

11. The front of the instrument adopts a large LCD screen display, which intuitively shows the process and status. Even if the microcomputer and the instrument are not in the same room, it does not affect the use. At the same time, it improves the convenience of the weighing process, making the measured values more consistentcountryMark.

12. Adopting software self detection function, the stability of the instrument will not be affected by photoelectric sensor errors, and the humanized prompt function will be added.

13. Optional compressed air station, suitable for users who cannot replace nitrogen gas.
