The original biomass into coal and coal-forming geological and geographical conditions, the composition and properties of the different regions of the coal is very different. Coal is a heterogeneous mixture composed of two parts of the organic and inorganic substances, ore processing mainly organic matter. Organic matter, you can burn. Also known as the combustible body.magnetic separator suppliers Inorganic substances, mainly a variety of mineral impurities, usually does not burn.
The nature of the coal is divided into the physical properties, chemical composition, technological properties and combustion properties.
The physical properties of coal, including coal and rock composition, color, luster, density, hardness, electrical conductivity, thermal conductivity, heat resistance, magnetic properties, particle size composition of the mud level.
Coal rocks can be divided into four kinds of vitrain, bright coal, dull coal, and fusain. They are very different in appearance. Vitrain and bright coal has a shiny, mirror coal fracture was conchoidal. The texture is more dense. Dark coal and fusain are dull, dull coal, hard texture without bedding, the fusain like wood chips. Macerals have a major impact on the nature and use of coal.
The chemical composition of coal, including the elements and industrial analysis.
Elements of coal
Coal is the transition from organic minerals from plant remains. Its elements is very complicated. It is mainly composed of six kinds of elements carbon, hydrogen, oxygen, nitrogen, sulfur, phosphorus, and also contains a small amount of fluorine, chlorine, arsenic, boron, lead, mercury and other elements and trace amounts of germanium, gallium, vanadium, uranium and other rare elements .
The carbon and hydrogen is the main component of coal, when burned, can release a lot of heat. In general, the elements of the organic matter in the coal as the coal rank and regular changes. The higher the coal rank, the higher the carbon content, the lower content of hydrogen and oxygen.
Industrial analysis of two coal
In order to understand the quality of coal to determine the type of coal processing and utilization of coal industry analysis, including the determination of coal moisture, ash, volatile matter and fixed carbon 4.
