Product name: anthracite,
product description:
Anthracite, commonly known as white coal or red coal. It is the coal with the greatest degree of coalification. Anthracite has high fixed carbon content, low volatile yield, high density, high hardness, high ignition point, and no smoke when burning. Black is hard and has metallic luster. Rubbing with fingers does not cause pollution, the fracture is in the shape of a shell, the flame is short and little smoke when burning, and the flame is blue-blue. The coke is non-sticky and does not form coke. Generally, the carbon content is above 90%, and the volatile matter is below 10%. No thickness of colloidal layer. The calorific value is about 5500-7100 kcal/kg.
Product application:
As anthracite has the characteristics of low internal ash, low sulfur, high calorific value, good thermal stability, high fixed carbon, high ash melting point and high mechanical strength, it is mainly used in chemical industry, electric power, metallurgy, building materials and other major coal-consuming industries, and has a wide range of applicability. Washing lump coal is the high quality raw material coal for chemical gasification. Pulverized coal is mainly used in blast furnace injection and sintering. Final coal is a good thermal coal, but also can be used in chemical industry, building materials and civil and other fields, and consumption increases year by year.
