1. Thermal coal is the coal used to generate electricity. Specifically, the coal is ground into powder and burned in the boiler of the thermal power plant, and the water in the boiler absorbs heat and turns into steam with certain parameters to drive the steam turbine to rotate, and the steam turbine drives the generator to generate electricity, which is used for power generation, so it is called thermal coal.
2. After washing the coal, the raw coal removes the gangue in the coal and becomes a high-quality coal suitable for special purposes, that is, refined coal. Refined coal can be divided into coking coal for smelting and other coking coal.
Coking coal for smelting, its particle size is less than millimeters, and the ash content is less than or equal to 12 5% referred to as smelting coal; For other coking coals, the particle size is also divided into three types: less than millimeters. The ash content is between 12 5% and 16%, referred to as other refined coal.

A type of coal. The base color is black, hard, and can be used to carve handicrafts, also known as charcoal.
Coal essence, also known as jet. It has a bright bitumen and metallic luster. Black, dense and tough.
There are two kinds, one is a high-grade coal, the main component is carbon C, which is lighter than ordinary coal. The other is petrified very thoroughly, the main ingredient is not charcoal, the density is relatively large, heavier than coal, and the luster is more beautiful after carving and processing. Exists between coal seams.
It is one of the most important coal production bases in China in the 20th century, with the reputation of "coal capital", and is famous for its long mining history, magnificent scale, advanced technology and profound industrial culture.
Fushun is also the main production area of amber in China, with a long and exquisite inheritance of coal essence amber carving and processing skills, and is the world-renowned "capital of black gold and jade". Fushun is also a very famous tourist attraction, such as: Gaoer Mountain Park, Hunhe River Source.
Difference Between Coal and Amber:
First, when we burn a piece of amber and a piece of coal at the same time, the amber will have a slight black smoke and a slight rosin fragrance; Coal also has black smoke, but its taste is kerosene-like. Second, if amber is analyzed by X-ray diffraction, it will not be reflected by X-ray diffraction because it is amorphous. Thirdly, analyzing the differences between the two, we will find that the amber curve has no obvious peaks and valleys and loses focus, which is much more complex than coal.

The difference between firewood coal and refined coal: firewood coal is the mineral coal with the lowest degree of coalification. A brownish-black, matte low-grade coal between peat and bituminous coal.
Rich in volatile matter, it is easy to burn and smoke when transported. Both belong to coal, but coal essence belongs to the essence of coal. First of all, let's talk about coal dissipation, coal is a kind of fossil fuel, large like a stone, the carbon element in coal can make the fire burn vigorously, mainly used for combustion and heat.
Coal essence is a particularly high-grade coal, also known as jet. Because the density of coal essence is very small, it is not very heavy to pick up, especially light, and the use of coal essence is not in combustion (used to burn is the small use of large side bridge plum material), coal essence also has another name called black gem, that is to say, coal essence can be used to make arts and crafts, carving crafts and decorations and so on.

Clenedcoal refers to high-quality coal that is suitable for some special purposes after being mechanically processed by the coal washing plant, which reduces the ash and sulfur content, removes some impurities, and is suitable for some special purposes.
Thermal power plants, chemical plants, steel plants, and some production units will be used, burning gas, drying, heating, and are extremely widely used.

Coal products are divided into five categories and 29 varieties according to their uses, processing methods and technical requirements ["Classification of Coal Products Varieties and Grades" (GB T 17608-2006)). The specific classifications and varieties are as follows:
1) Refined coal. 1-1 Coking coal for smelting, 1-2 Coking coal for other purposes, 1-3 Clean coal for injection.
2) Coal washing.
2-1 Washed raw coal, 2-2 washed mixed coal, 2-3 washed coal, 2-4 washed pulverized coal, 2-5 washed extra large block, 2-6 washed large block, 2-7 washed medium block, 2-8 washed mixed medium block, 2-9 washed mixed block, 2-10 washed mixed small block, 2-11 washed granular coal.
3) Screening coal.
3-1 coal mix, 3-2 end coal, 3-3 pulverized coal, 3-4 extra large block, 3-5 large block, 3-6 medium block, 3-7 mixed block, 3-8 mixed medium block, 3-9 small block, 3-10 mixed small block, 3-11 grain coal.
4) Raw coal. 4-1 Raw coal, water mining raw coal.
5) Low-quality coal.
5-1 Raw coal, 5-2 slime, water mining slime.
According to the degree of coalification, all coal is divided into three categories: anthracite, bituminous coal and lignite, and then subdivided into 14 subcategories: anthracite, lean coal, lean coal, lean coal, coking coal, fertile coal, 1 3 coking coal, gas fertilizer coal, gas coal, 1 2 medium sticky coal, weak sticky coal, non-sticky coal, long-flame coal and lignite.

The classification upstairs is very comprehensive, in answer to the supplementary question, coal can be divided into lignite, bituminous coal, anthracite according to the generation age, of which bituminous coal is divided into coking bituminous coal, general bituminous coal, the latter is mainly used as thermal coal, the refined coal you said, is already a product of coal processing,

Explanation of coal essence is a type of coal. The color is black, the quality is hard, and it can be used to carve handicrafts. China is mainly produced in Fushun. Also known as charcoal essence.
The word decomposition Explanation of coal Coal é Ancient plants were buried underground, and under conditions of impermeable air or insufficient air, they were subjected to high temperature and high pressure in the ground and deteriorated over time: coal mines. Coalfield.
Seam. Coal gas. Coal tar.
Jet. The black ash condensed by the flue gas is the main raw material for ink making: Qinglu coal.
Explanation of Songmei Jing Jing Jing ī Shanghao white rice: "not tired of eating". Fine, as opposed to "coarse" :
Precision. Filigree. Precise.
Refined. Intensive reading. Selected.
Carefully. Intensive research. Finely carved.
Smart, thoughtful : Tough. Shrewdness.
Astute. The purest part of matter, the thing that is refined: the essence. Elite.

Summary. Both belong to coal, but coal essence belongs to the essence of coal. First of all, let's talk about coal, as we all know, coal is a fossil fuel, large chunks like stones, the carbon in coal can make the fire burn vigorously, mainly used for combustion and heat.
Coal essence is a particularly high-grade coal, also known as jet. Because the density of coal essence is very small, it is not very heavy to pick up, especially light, and the use of coal essence is not in combustion (used to burn is overkill), coal essence also has an alias called black gemstone, that is to say, coal essence can be used to make arts and crafts, carving crafts and decorations and so on.
What is the difference between coal essence and coal.
Both belong to coal, but coal essence belongs to the essence of coal. First of all, let's talk about coal burning, coal is a kind of fossil fuel, large as a stone sinks, the carbon in coal can make the fire burn vigorously, mainly used for combustion and heat. Coal essence is a particularly high-grade coal of the oak species, also known as jet.
Because the density of coal essence is very small, so the beam is not very heavy, especially light, and the use of coal essence is not in combustion (used to burn is overkill), coal essence also has another name called black gem, that is to say, coal essence can be used to make arts and crafts, carving crafts and decorations and so on.

The anthracite color is also black, and the lines drawn are black!
