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.

PS: I have heard that it is planned to build big diesel engine power power plants with an extra steam process feed by the exhaust gas of the engine. This combination should reach about the same efficiencies as classical combined cycles. Does anybody know about a realised one? Am 05.01.2010 20:20, schrieb starrfred

Jan 01, 2021· The fact that the SII kiln uses the excess steam from the power plant for heat was critical. A direct-fired kiln, burning some type of fuel to heat water in a boiler, would have required an air quality permit. However, it is highly unlikely that state officials would issue a permit given the region’s air pollution problems.

CO 2 is the primary anthropogenic greenhouse gas, accounting for 77% of the human contribution to the greenhouse effect in recent decade (26 to 30 percent of all CO 2 emissions). Main anthropogenic emissions of CO 2 come from the combustion of fossil fuels. CO 2 concentration in flue gases depends on the fuel such as coal (12–15 mol-% CO 2) and natural gas (3-4 mol-% CO 2).
