Coal testing equipment laboratory equipment Hebi Coal Hua Cheng professional sales assured selection

After the complete combustion of the coal residue remaining called ash, ash exceptionally ash in the ash and internal. External ash from the roof and folders research in rock fragments, it is reasonable or not the mining methods have a great relationship. Most external sorting through ash can be removed. Inherent ash is inorganic raw coal into the plant itself contains, the higher intrinsic ash, coal washability worse. Ash is hazardous. Increase in coal ash, reduce heat, increase the amount of slag, coal slagging easy; general ash every 2% increase reduce heat around 10okcal / kg?. Increase in metallurgical coal ash, blast furnace utilization coefficient reduced coke strength decreased, increased use of limestone; ash every 1% increase in coke strength decreased 2%, blast furnace production capacity of nine 3% decline in the amount of limestone increase 4% ZDHW-600B type. microcomputer automatic calorimeter ● ZDHW-600B microcomputer automatic calorimeter Features: ■ The system runs on more than one operating system WinsowsXP, human-computer interaction and, the school that will. ■ automatic injection, drainage, will not overflow, without adjusting the water temperature. Using scientific efficient algorithms, automatic correction constant, high data accuracy. System is reliable, can be test after data processing. Using serial communication technology, low failure rate, the use of environmental requirements relaxed. (According to user needs, the visibility single dual control) ● ZDHW-600B microcomputer automatic calorimeter technical parameters: ■ Accuracy: meet the national standard GB / T213-2003 ■ use of the environment: 5-40 ℃ ■ Temperature Resolution: 0.0001 ℃ ■ Power: AC220V ± 15% 50Hz
