What kind of coal is used in the coking plant? Where can I find companies that do flue gas treatment?

The types of coal that can be used for coking coal or coking coal blending include gas coal, gas fat coal, 1/3 coking coal, fat coal, coking coal, lean coal, lean lean coal.
Coking coal
coking and cohesiveness
is the most important indicator. Under normal circumstances, there are very few types of coal that meet these two conditions and other indicators (such as ash, sulfur, volatile matter, moisture, etc.). Therefore, coal is generally blended now, and several kinds of coals are mixed in a certain proportion to meet the requirements of coking coal. To say that the consumption is large, it must be more coking coal and lean coal.
The price of coal is relatively poor now, and the price of coking coal is generally 1000-1200 yuan / ton. Depends on your coal quality and other factors
It depends on the coal input standard of a coking plant. The evaluation methods of coal quality include: chemical method, coal petrological method, technological method, physical and physical-chemical method. Among them, many coking plants are analyzed by chemical methods and physical methods. There are two standards for lean coal: 1 volatile matter (dry ashless grade, the following volatile matter is based on this standard)> 10-20, adhesion index> 20-65. 2 volatile matter> 20-28, viscosity Knot index>50-65 Standard for coking coal: volatile matter>10-28, caking index>65, Y value less than or equal to 25m, b value less than or equal to 150. Among them, the coal with less sulfur is better for blast furnace ironmaking, that is, the better the quality of the coal.
