What are the standards for standard anthracite coal?

Standard Anthracite CoalOur standards primarily encompass the following aspects:

Volatile matter. Volatile matter refers to the total amount of gases and liquid components that coal loses at high temperatures. The lower the volatile matter content, the better the coal's combustion properties. Generally, the volatile matter content of anthracite coal ranges from 5% to 15%.

Fixed Carbon. Fixed carbon refers to the non-volatile matter that remains when a coal sample is heated to a high temperature in a dried state. Coal with a high fixed carbon content has a high calorific value, stable combustion, and is an important indicator of high-quality anthracite. The fixed carbon content of anthracite is generally between 75% and 85%.

Ash content. Ash content refers to the total amount of non-combustible parts in coal. The higher the ash content, the greater the degree of ashing in the coal. Generally, the ash content of anthracite is within 8%.

Sulfur Content. Sulfur content refers to the total amount of sulfur compounds in coal. The higher the sulfur content, the more polluting the coal is. Generally, the sulfur content of anthracite coal is 0.6% or less.

Calorific Value. Calorific value refers to the amount of heat released per unit mass of coal. The higher the calorific value, the better the quality of the coal, generally speaking.Standard Anthracite CoalThe calorific value exceeds 5,500 kcal/kg.

Furthermore,Standard Anthracite CoalThe bonding index and moisture content are also important indicators of its quality. It's important to note that the standards for smokeless coal may vary by region and application.
