How to identify bituminous coal and anthracite coal

Identification tips:

1. The main difference between bituminous coal and anthracite coal is the volatile matter and moisture, as well as the carbon content in the flammable base. Anthracite coal has lower volatile matter and moisture than bituminous coal, and has a higher precipitation temperature. It is also the coal with the largest low-level calorific value. It is more difficult to start a fire and burn, so there is almost no smoke and flame when burning.

2. Anthracite is black and hard, with metallic luster, high density, hardness, high ignition point, and does not emit smoke when burning. The fracture is shell-shaped, the flame is short and less smokey when burning, no coking, and no colloid layer thickness. Sometimes, those with extremely large volatile matter content are called semi-anthracite coal, and those with extremely small volatile matter content are called high anthracite coal.

Bituminous coal includes long-flame coal, gas coal, fat coal, coking coal, lean coal, lean coal, etc. Gray to black, with asphalt luster to diamond luster, usually with a strip-like structure, does not contain native humic acid, most bituminous coal has cohesiveness, and the flame is high and smoky when burning.

3. Anthracite coal lumps are mainly used in chemical fertilizers, ceramics, manufacturing and forging and other industries. Anthracite pulverized coal is mainly used in the metallurgical industry, such as blast furnace injection. Bituminous coal has abundant reserves and can be used as power coal, fuel cells, catalysts or carriers, soil conditioners, filters, building materials, adsorbents to treat wastewater, etc.

4. Anthracite is not prone to spontaneous combustion during storage and is convenient for long-distance transportation. Bituminous coal is easier to catch fire and burn completely.
