Anthracite

Name: high quality coal

Class: coal mine

Formula: C

Molecular weight: 12

Color: black

Gloss: metallic luster

Application: Fuel, Anthracite filter


Description 

Anthracite is commonly known as white coal or red coal. It is the coal with the highest degree of coalification. Anthracite has a high fixed carbon content, low volatile yield, high density, high hardness, high ignition point, and no smoke when burning. It is black and hard. It has a metallic luster. No coking, no oven, white ash.

Generally, the content of carbon is above 80%, and the volatile matter is below 10%. The calorific value is about 6000-6500 kcal / kg. Sometimes, anthracite with an extremely high volatile content is called semi-anthracite, and the extra low is called high anthracite.


Anthracite as fuel

Anthracite as a fuel is mainly used in tunnel kiln, blowing road, smelting furnace, lime kiln, sintering furnace and single-ended gas generator.

Recommendations

1. Anthracite spray coal is recommended for tunnel kiln, tobacco furnace, side blowing furnace, and sintering furnace.

2. Washed anthracite spray coal is recommended for steel mill blown furnace.

3. Anthracite seed coal or lump coal is recommended for lime kilns and single-stage gas generator.


Anthracite filter

Standard coal:

The standard filter material is made of high-quality carbon block, which is selected, crushed and screened. It has good appearance gloss, multi-angled granular shape, strong compressive and wear resistance, and is generally used for double-layer and three-layer filtration.

TJP filter material:

The TJP type anthracite filter material is produced by the Japanese Waterway Co., Ltd. standard, and the quality is fully up to the Japanese standard. It is mainly used for steel rolling water treatment in steel systems and advanced treatment of sewage in petrochemical industry. It is also suitable for advanced water filtration in precision manufacturing and aerospace navigation.
