Coal tar shampoo is a standard medical treatment for psoriasis, seborrheic dermatitis, eczema, and other skin diseases for decades. It is known to help with the hardening and thickening of the scalp skin to decelerate the growth of skin cells. It improves the composure of your hair and scalp while also reducing itching due to dead skin.

It is a bituminous coal which allows the production of a coke suitable to support a blast furnace (BF) charge. It is distinguished by the strong low-density coke produced when the coal is heated in a low oxygen (O2) environment or in absence of air to reduce mineral impurities (e.g. less sulphur, phosphorus).

Coal can be turned into gases and liquids that can be used as fuels or processed into chemicals to make other products. These gases or liquids are sometimes called synthetic fuels or synfuels. Synthetic fuels are made by heating coal in large vessels. These fuels produce fewer air pollutants when burned than burning coal directly.

Coal combustion products ( CCP 's) are the inorganic residues that remain after pulverized coal is burned. Coarse particles (bottom ash and boiler slag) settle to the bottom of the combustion chamber), and the fine portion (fly ash, fig. 1) is removed from the flue gas by electrostatic precipitators or other gas-scrubbing systems.

It is primarily used for generating electricity, via coal-burning power plants. The principle is simple. Combusted in a boiler, the coal releases heat that converts water into steam. This drives a turbine connected to a generator that produces electricity. As it passes through a condenser, the steam cools down, becoming water again.
