low volatile coal boiler power plant - Lorchen's Bauernhaus

Bituminous coal has been increasingly used as the main fuel for pulverized coal (PC)-fired boilers for thermal power plants in Japan, and demand for bituminous coal has also increased worldwide. Consequently, PC-fired boilers are now required to use not only bituminous coal but also low-volatile coals like semi- anthracite and anthracite.

Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
