The Differences Between Standard Anthracite and Sub-bituminous Coal

‌Standard Anthracite CoalThis coal features a high fixed carbon content and low volatile matter, with volatile matter typically below 10%. It has a high density, hardness, and ignition point, and burns without smoke. The carbon content of this coal is generally above 90%, with no glazing layer thickness, and its calorific value is approximately 8,000 to 8,500 kg. Standard anthracite coal is commonly used in applications requiring high calorific value and low pollution due to its high calorific value and low pollution characteristics.

Sub-bituminous coal refers to a type of coal that falls between anthracite and bituminous coal in terms of volatile matter content. It has a particularly high volatile matter content, lying between those of anthracite and bituminous coal. The release temperature of volatiles in sub-bituminous coal is higher, and although it produces less smoke during combustion, compared to...Standard Anthracite CoalIts smoke volume is relatively high. Semi-anthracite coal has a wide range of applications, including power generation and heating, among others.

Overall, standard anthracite coal is more suitable for high-end applications with strict pollution control requirements, such as advanced fuels or special industrial uses, due to its low volatile matter and high calorific value. In contrast, semi-anthracite coal, with its moderate volatile matter, holds value in a wider range of applications.
