What is anthracite and what is the difference between bituminous coal and anthracite

Anthracite is the coal with the deepest degree of coalification, with the most carbon content, not much ash, less moisture, and high calorific value, up to 25000 32500kj kg, the volatile matter release temperature is higher, its coke has no cohesiveness, ignition and burn are more difficult, smokeless when burning, and the flame is blue.

The coal sample is heated by air isolation under specified conditions, and the organic matter in the coal is heated and decomposes a part of the liquid state (in this case, the vapor state) and gaseous products with small molecular weight, which are called volatiles. The fraction of volatiles in the mass of a coal sample becomes the volatile yield, or simply volatile. Coal with a dry ash-free base as the analytical base and a volatile content of less than 10% is called anthracite.

Anthracite with a volatile content greater than less than 10% is called anthracite No. 3.

Anthracite is commonly known as white coal or red coal. Coal with the greatest degree of coalification. Black is hard with a metallic sheen.

It is not stained by grease friction, and the fracture is in the shape of a shell, and the flame is short and less smoke when burning. No coke. Generally, the carbon content is more than 90%, and the volatile matter is less than 10%.

No gum layer thickness. The calorific value is about 8000-8500 kcal kg. Sometimes the most volatile content is called semi-anthracite; The smallest ones are called high anthracite.

In Shanxi, Yangquan and Henan Jiaozuo are the main production areas.

Anthracite coal has high fixed carbon content, low volatile yield, high density, high hardness, high ignition point, and no smoke when burning. No. 01 anthracite is old anthracite; No. 02 anthracite is a typical anthracite; No. 03 anthracite is a young anthracite. For example, Beijing, Jincheng and Yangquan are anthracite.

The differences between bituminous coal and anthracite are as follows.

1. How much smoke is produced. Anthracite soot is a little less, bituminous coal smoke is larger, anthracite demand is more and more, now people regard health as particularly important, burning smoke is difficult and harmless to avoid any harm to the body.

2. The continuous burning time is different. Anthracite has many names, also known as chaotic white coal.

Red coal has a strong staying power, and it is the longest lasting coal in coal. Bituminous coal is a type of coal after the conversion of lignite, the continuous combustion level of bituminous coal is not long, it can only rank in the middle of coal, and the continuous combustion time is higher than that of lignite and lower than that of anthracite, but the firepower of bituminous coal is stronger than that of anthracite.

3. Water content.

Different. The water content of anthracite is lower than that of bituminous coal, and the smoke that comes out is less, and the temperature of anthracite precipitation is higher, which belongs to the calorific value in coal.

Maximum, almost smokeless when burning, bituminous coal feels foggy when burning.

Coal is a very important resource in life, many places are inseparable from the use of coal, there are several kinds of coal, bituminous coal and anthracite, these two kinds of coal have their own characteristics, each has its own advantages, now most of them are the use of anthracite, rarely use bituminous coal.

From the perspective of the application of the two, the application industry of the two is not the same, anthracite is mainly used in ceramics, fertilizer and some forging industry, anthracite is mainly used in the metallurgical industry, the reserve of bituminous coal is relatively rich, can be used as a source of power, can also be made into a filter, coal has a good filtering effect, is many people do not think.

Bituminous Coal Difference Between Smokeless:

1. How much smoke is produced.

Anthracite soot is a little less, the smoke of bituminous coal is larger, the demand for anthracite is more and more, and now people regard health as particularly important, and the smoke from burning will inevitably cause any harm to the body.

2. The continuous burning time is different.

Anthracite has many names, also known as white coal and red coal, which has a strong staying power and is the longest lasting coal. Bituminous coal is the type of coal after the conversion of lignite, the continuous combustion level of bituminous coal is not long, it can only rank in the middle of coal, and the continuous combustion time is higher than that of lignite and lower than that of anthracite, but the firepower of bituminous coal is stronger than that of anthracite.

3. Different water content.

The water content of anthracite is lower than that of bituminous coal, the smoke that comes out is less, and the temperature of anthracite precipitation is higher, and it is the largest calorific value in coal, and it is almost smokeless when burning, and bituminous coal feels foggy when burning.

Anthracite uses

China is a big coal producer, especially Shanxi, China. When China was just starting to develop, almost all coal mines were transported from Shanxi to the whole country. Anthracite is a new type of coal, which does not have high calorific heat, but its carbon content is still very high.

It is still very versatile, for example, it can be used in chemical fertilizers, and of course, it can also be used in the production of ceramics.

Anthracite is also needed for ironmaking. If it is applied to the physical industry, then it is the calciner and burner, which are generally used in the steel industry. In the past, people may still use coal to live, but because it is not clean to the point of producing carbon monoxide, it is gradually not applicable.

Anthracite is commonly known as white coal or red coal. It is the coal with the largest degree of coalification.

Anthracite coal has high fixed carbon content, low volatile yield, high density, high brightness of hard draft, high ignition point, and no smoke when burning. Black is hard with a metallic sheen. It is not polluted by grease friction, and the fracture is in the shape of a wide shell, and the flame is short and less smoke when burning. No coke.

Anthracite generally has a carbon content of more than 90 percent and volatiles of less than 10 percent. No gum layer thickness. There are about 8,000 to 8,500 kcal per kilogram, and sometimes the largest volatile content is called semi-anthracite, and the smallest is called high anthracite.

Summary. Hello, the differences are as follows:

Hello, the differences are as follows:

The differences are different combustion characteristics and different energy use.

1. Different combustion characteristics: bituminous coal produces a large amount of smoke and smoke when burning, and the flue gas in the combustion process contains high sulfur and nitrogen compounds, which causes pollution to the environment of the segment, while anthracite coal produces less smoke and smoke when burning, has high combustion efficiency and less environmental pollution.

2. Different energy utilization: anthracite has high calorific value and good energy utilization efficiency, which is suitable for power generation, heating and other high-efficiency energy sources, while bituminous coal has low calorific value and poor energy utilization efficiency, so it is not suitable for use as high-efficiency energy.
