Microcomputer Automatic Quantitative Bottle Refrigeration Calorimeter Solid biomass fuel calorific value tester
2.Scope of application
It is mainly used to determine the calorific value of combustibles such as coal, coke, petroleum, cement black raw materials, biomass fuels, etc., in line with national standards. Performance characteristics:
1. The liquid level visual function is added to facilitate the progress of water addition when adding water, and to replenish the instrument with water in time after long-term experiments. 2. It has a quantitative water volume function. The quantitative water cup ensures the stability of the water volume in the inner cylinder, ensuring the stability and accuracy of the experimental results. 3. The electronic refrigeration speed is fast, ensuring that the temperature difference between the inner and outer cylinders of the instrument meets the national standard requirements.
4. The test speed is fast, and the test cycle is about 18 minutes.
5. Thermal capacity stability <0.2% precision <0.1% temperature resolution 0.0001K
6. Automatic water temperature adjustment (the temperature of the inner barrel is about 1K higher than that of the outer barrel at the end point, which meets the national standard requirements)
7. The repeatability and reproducibility of the calorific value test are better than the national standard requirements.
8. High degree of automation, automatic quantitative water volume in the inner barrel, automatic control of the temperature difference between the inner and outer barrels of the instrument, and automatic completion of the entire test process. 9. Adopting Windows operating system, one machine with multiple controls is realized, and the tests between them do not affect each other, and the software operation stability is high.
10. It can work continuously for a long time, and the stainless steel vacuum inner barrel is durable.
