Anthracite, generally known as white coal
or smokeless coal, is the coal of maximum degree coalification. Its coal
content material reaches high to 90 to 98 percent, whilst hydrogen content is
generally less than 4 %. It has many characteristics like low volatiles, higher
strong coal, higher 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 viewpoint of Anthracite Supplier, they contact
anthracite of fantastic volatile content material semi-anthracite and that of
small high 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 utilized as fuel for blowing and sintering iron ore in blast
furnace but, especially for Calcined Anthracite as
raw material for manufacturing various carbon supplies like carbon electrode,
anode paste and activated coal. Some of excellent quality may be manufactured
into briquette coal for aviation use for the purpose of thermal insulation for
plane engine and car motor.
In detail, anthracite has following
applications as beneath.
Firstly, chemical material. Anthracite is
the essential raw material for synthesizing ammonia and creating nitrogenous
fertilizer and urea. Those of low ash and low sulfur can nonetheless be utilized
to manufacture graphite as New Graphite Material.
Of course, other than graphite, this sort of anthracite also has wide
application in producing calcium carbide, carbon electrode, silicon carbide,
carbon fiber and some others.
Secondly, blast furnace injection coal.
Using the daily enlargement of steel productivity and constant development and
perfection of critical technology in blast furnace coal injection, blast
furnace coal injection is playing a more and more important function in saving
smelting cost in steel business. Anthracite becomes the best option within this
application for very high carbon content. To make use of anthracite, some
within the form as Anthracite
Ball as the partial replacement of metallurgical coke, on one hand,
decreases pig iron price 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 significantly relieving the
intensive situation of coking coal resource.
Thirdly, electricity generation fuel.
Anthracite has currently turn out to be excellent fuel in electrical energy
generation for the traits of higher heat and non-smoke in burning.
Nevertheless, just as Coal
Supplier indicates, it is still not extensively applied only for the reason
of relatively high cost. But with daily strengthened atmosphere 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 further popularized as electrical energy generation fuel.
