煤碳除含有可燃物还含矿物质。此矿物质源于成煤母体和成煤过程及采掘过程中混入的岩石。碳酸盐是矿物质的组成部分之一。通常它的含量较少只占煤的1%左右,但在碳酸盐丰富地区生成的煤和一些褐煤,其含量可达10%以上,在可燃碳酸盐页岩中甚至高达25%。煤在燃烧过程中伴随着碳氢有机物的热解、氧化转变为二氧化碳和水的同时,碳酸盐也受热 In addition to combustible coal also contains minerals. This mineral originates from the coal that is incorporated into the coal and during the coal formation and during the excavation. Carbonates are one of the components of minerals. Often, its content is less than 1% of coal, but coal and some lignites generated in carbonate-rich areas can reach more than 10% and even up to 25% in combustible carbonate shale. Coal is accompanied by the pyrolysis of hydrocarbons in the combustion process, while the oxidation is converted to carbon dioxide and water. Carbonates are also heated
