Detection of the external water supply coal

Hebi City, Cheng Instrument Co., Ltd. specializing in the development of coal production and sales of China-instrument laboratory equipment cheap HCSC-8000 / 8000F moisture analyzer Features: ■ the ATMER import SCM automates the entire process of measuring, can be tested at the same time 9 samples, serial communications, the allocation of import precision balance, high measurement accuracy. ■ position detection using non-contact electronic switch, stable and reliable. ■ single serial operation control, simple and reliable. ■ Special design, smaller microwave leakage. Technical parameters: ■ Power supply voltage: AC220V ± 15% 50Hz ■ Weighing Resolution: 0.001g ■ Moisture accuracy: better moisture coal country is divided into two, when one inherent moisture (Minh) by plants into coal Water contains: two outer moisture (Mf), is attached to the coal surface and cracks in the water during mining, transportation and the like. Is the sum of total moisture in coal, regardless of external and internal moisture. 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.
