煤炭介紹
煤炭,簡稱煤,是遠古植物遺骸,埋在地層下,經過地殼隔絕空氣的壓力和溫度條件下作用,產生的碳化化石礦物,主要被人類開采用作燃料。
煤炭對于現代化工業來說,無論是重工業,還是輕工業;無論是能源工業、冶金工業、化學工業、機械工業,還是輕紡工業、食品工業、交通運輸業,都發揮著重要的作用,各種工業部門都在一定程度上要消耗一定量的煤炭,因此有人稱煤炭是工業的“真正的糧食”。是十八世紀以來人類世界使用的主要能源之一。
Coal, referred to as coal, is the ancient plant remains, buried in the ground, through the earth"s crust to isolate the air pressure and temperature conditions, resulting in the carbonation of fossil minerals, mainly used as a fuel for human.
Coal for industrial modernization, whether it is heavy industry, light industry; both the energy industry, metallurgy industry, chemical industry, machinery industry, or textile industry, food industry, transportation play an important role, various industrial sectors are to a certain extent, to a certain amount of coal consumption. So it is called coal industry ";real food";. Is one of the main energy sources in the world since eighteenth Century.

煤炭用途
煤炭的用途十分廣泛,可以根據其使用目的總結為兩大主要用途動力煤和煉焦煤。
一、動力煤
1)發電用煤:中國約1/3 以上的煤用來發電,目前平均發電耗煤為標準煤370g/(kW·h)左右。電廠利用煤的熱值,把熱能轉變為電能。
2)蒸汽機車用煤:占動力用煤2%左右,蒸汽機車鍋爐平均耗煤指標為100kg/(萬噸·km)左右。
3)建材用煤:約占動力用煤的10%以上,以水泥用煤量較大,其次為玻璃、磚、瓦等。
4)一般工業鍋爐用煤:除熱電廠及大型供熱鍋爐外,一般企業及取暖用的工業鍋爐型號繁多,數量大且分散,用煤量約占動力煤的30%。
5)生活用煤:生活用煤的數量也較大,約占燃料用煤的20%。
6)冶金用動力煤:冶金用動力煤主要為燒結和高爐噴吹用無煙煤,其用量不到動力用煤量的1%。
二、煉焦煤
中國雖然煤炭資源比較豐富,但煉焦煤資源還相對較少,煉焦煤儲量僅占中國煤炭總儲量27.65%。
煉焦煤類包括氣煤(占13.75%),肥煤(占3.53%),主焦煤(占5.81%),瘦煤(占4.01%),其它為未分牌號的煤(占 0.55%);非煉焦煤類包括無煙煤(占10.93%),貧煤(占5.55 % ),弱粘煤(占1.74%),不粘煤(占13.8%),長焰煤(占12.52%),褐煤(占12.76%),天然焦(占0.19%),未分牌號的煤(占13.80%)和牌號不清的煤(占1.06%)。
煉焦煤的主要用途是煉焦炭,焦炭由焦煤或混合煤高溫冶煉而成,一般1.3 噸左右的焦煤才能煉一噸焦炭。焦炭多用于煉鋼,是目前鋼鐵等行業的主要生產原料,被喻為鋼鐵工業的“基本食糧”。
The use of coal is very wide, and it can be summarized as two main uses of power coal and coking coal according to its purpose.
First, the power of coal
1) power generation coal: China about 1/3 or more of the coal used to generate electricity, the current average power generation coal consumption for the standard coal 370g/ (kW / h) or so. Heat energy is converted into electric energy by utilizing coal calorific value of power plant.
2) steam locomotive with coal: about 2% of the power of coal, steam locomotive boiler average coal consumption index is 100kg/ (million tons / km) or so.
3) building materials with coal: about 10% of the power to use coal, the maximum amount of cement with coal, followed by glass, brick, tile, etc..
4) general industrial boiler coal: in addition to thermal power plants and large heating boilers, the general enterprise and heating with a wide range of industrial boilers, large and dispersed, with a total of about 30% of the coal consumption of power.
5) life with coal: the number of domestic coal is also larger, accounting for about 20% of the fuel used coal.
6) power coal for metallurgical use: the main sintering and blast furnace injection of anthracite coal, the amount of less than 1% of the power consumption of coal.
Two, coking coal
Coking coal is the main use of coking coal, coke or mixture of high temperature smelting of coal, generally about 1.3 tons of coking coal in order to refine a ton of coke. Coke used for steelmaking, is currently the main raw material for the production of iron and steel industry, iron and steel industry has been hailed as the basic food ";";.
