Introduction on Main Application of Anthracite

Anthracite, generally recognized as white coal or smokeless coal, will be the coal of maximum degree coalification. Its coal content reaches higher to 90 to 98 percent, while hydrogen content is usually much less than four percent. It has many traits like low volatiles, higher strong coal, high hardness, difficult abrasion, higher fire point, shot flame, weak chemical reaction, non-cohesiveness, no thickness of colloidal layer and non-smoking when burning. The caloric value is approximately 6000 to 6500 kcal per kg. Occasionally, from the perspective of Anthracite Supplier, they contact anthracite of fantastic volatile content material semi-anthracite and that of small higher anthracite.

Anthracite is used in synthesis ammonia manufacture as gas creating raw material and nitrogenous fertilizer production. With properties of low ash, low sulfur and great abrasiveness, anthracite can not only be used as fuel for blowing and sintering iron ore in blast furnace but, especially for Calcined Anthracite as raw material for manufacturing various carbon materials like carbon electrode, anode paste and activated coal. A few of excellent quality can be manufactured into briquette coal for aviation use for the purpose of thermal insulation for plane engine and vehicle motor.

In detail, anthracite has following applications as below.

Firstly, chemical material. Anthracite is the essential raw material for synthesizing ammonia and producing nitrogenous fertilizer and urea. Those of low ash and low sulfur can still be used to manufacture graphite as New Graphite Material. Of course, other than graphite, this kind of anthracite also has wide application in creating calcium carbide, carbon electrode, silicon carbide, carbon fiber and a few others.

Secondly, blast furnace injection coal. With the daily enlargement of steel productivity and continuous improvement and perfection of critical technologies in blast furnace coal injection, blast furnace coal injection is playing a more and more essential role in saving smelting price in steel industry. Anthracite becomes the very best choice in this application for very high carbon content. To use anthracite, some within the type as Anthracite Ball as the partial replacement of metallurgical coke, on one hand, decreases pig iron cost by lowering iron and coke ratio, and on anther, saves coking investment by developing much less coke oven. Therefore, it decreases air pollution caused by coking at the same time of greatly relieving the intensive situation of coking coal resource.

Thirdly, electrical energy generation fuel. Anthracite has already turn out to be excellent fuel in electrical energy generation for the characteristics of higher heat and non-smoke in burning. However, just as Coal Supplier indicates, it's still not widely applied only for the purpose of fairly higher price. But with daily strengthened environment protection force, a batch of energy plants fueled by anthracite, merger lean coal or perhaps the blender are put into production in succession. Anthracite is certainly to become additional popularized as electrical energy generation fuel.
