Coal grade G (Gas coal) is one of the universal brands. It belongs to the energy, but it can already get coke from it. The structure of the stamp is more dense than that of long-flaming varieties, but it is inferior to them in strength. The color of the material is black, gloss matt or metal. Coal grade G burns well and produces a lot of heat. It contains less sulfur than anthracite, leaves a small amount of ash. For fire safety, the boilers under this brand should be equipped with afterburn cells. Special filters for the capture and condensation of volatile substances are installed at the thermal power plant.
