Coal testing equipment testing equipment, Hebi Coal Hua Chengxin reputation first

Moisture coal is divided into two, one inherent moisture when water (Minh), is contained by a plant into a coal; the second is external water (Mf), is attached to the surface and cracks in the process of coal mining, transport, etc. in the water. Total Moisture is the external and internal moisture coal, regardless of the sum. In general, the degree of metamorphism of coal, the lower the inherent moisture. Lignite, long-flame coal ordinary high inherent moisture, low lean coal, anthracite inherent moisture. The presence of moisture on the use of coal is extremely unfavorable, it is not only wasting a lot of transportation resources, and when coal as fuel, the coal moisture into steam, burn calories during evaporation; In addition, the moisture on the coking coal also generates some impact. Usually the water every 2% increase, reduce heat 100kcal / kg (kcal / kg); metallurgical coal moisture every 1% increase in coking time to extend the 5-10min ZDHW-300B microcomputer automatic calorimeter ● ZDHW-. 300B microcomputer automatic calorimeter Features: ■ The system runs on Windowsxp above systems, human-computer interaction and, the school that will. ■ automatic injection, drainage, will not overflow, without adjusting the water temperature.
