Introduction of anthracite coal

Anthracite has high fixed carbon content, low volatilization rate, high density, high hardness, high burning point, and not smoking when burning. Black is hard and metallic. It does not stain with grease, it is cut into a shell, and the flame is short and smoky when burned. No coking. The average carbon content is over 90 and the volatile substance is below 10. No gel thickness. The heat value is about 7,000 to 8000 kcal/kg. Sometimes it's called semi-anthracite; The small is called high anthracite. Anthracite by type can be divided into: 12 25 lump coal, lump coal, pulverized coal, lump coal, charcoal and charcoal, 38 method can be used according to the customer different boiler and recommend suitable and reduce the cost for the customer the species.

Anthracite filter material is a kind of filter material for water treatment industry and high quality anthracite as raw material, the selection of broken, powder, sieve process is widely used, such as double, three layers of filtering material quickly. Suitable for general acid, neutral alkaline treatment, have good ratio surface area, all indexes meet the construction department (CJ/t44-1999) standard. The filter of anthracite is used as a good material for double-layer rapid filter and three-layer filter and filter filter. It is an effective way to increase the amount of water in the filtration rate and improve the ability to eliminate the pollution by multiplying the amount of water in the area. It is widely used in the process of water quality processing in chemical, metallurgy, thermoelectric, pharmaceutical, paper, printing and dyeing, food, etc.

Characteristics of anthracite coal

1, black hard, metallic luster.

Heat, ignition point, heat stability good combustion without smoke.

High mechanical strength, high density, high hardness, low sulphur, low ash and low volatility.

High carbon content, high chemical activity, high melting point, high yield and low volatility.

Anthracite used

The main application of anthracite is fertilizer (nitrogen fertilizer, synthetic ammonia), ceramics, manufacturing and other industries. The main application of anthracite powder is used in the metallurgical industry for blast furnace blast (blast furnace blasting coal mainly includes anthracite, lean coal, coal and coal).

Coal for power generation: about one-third of the coal in our country is used for power generation, and currently the average power consumption is about 370g/(kW h). The power plant USES coal's thermal value to convert heat energy into electricity.

The steam engine USES coal: it accounts for about 2 of the power, and the average coal consumption of steam locomotive boilers is 100kg/(mt. Km).

3, the building materials use coal: about the l0 of the power to use coal, the cement coal quantity is bigger, the second is glass, brick, tile and so on.

4, general industrial boiler coal: in addition to the thermal power plants and large heating boiler, general enterprises and various types of industrial boiler for heating, the number of large and scattered, coal accounts for about 30 of the steam coal.

Coal for life: the number of coal in life is also greater, accounting for about 20 percent of coal.

Metallurgical power coal: metallurgical coal is mainly used for sintering and blast furnaces for non-smoking coal, which is less than 1 of the power consumption.

Anthracite coal and quartz sand filter material used in the promotion of double quick filter and three layer filter, cartridge filter material, increase the water yield per unit area is to improve the filtering speed and multiply section carrying capacity, reduce the project cost and reduce the area of effective way, widely used in chemical industry, metallurgy, thermal power, pharmacy, paper making, printing and dyeing, food, etc. In the process of the production water quality before and after treatment.
