200 mesh blast furnace injection pulverized coal, anthracite, refined coal, high calorific value, industrial boiler
Anthracite is a very precious coal resource, which is characterized by almost no smoke during combustion, hence the name "anthracite". In the field of industrial boilers, anthracite clean coal is used in a wide range of applications, especially in blast furnace injection, where it provides efficient energy**. Today we will take a detailed look at the characteristics and uses of this refined coal.
First, the characteristics of anthracite refined coal.
The characteristics of anthracite refined coal are mainly manifested in the following aspects:
1.High calorific value: Anthracite refined coal has a very high calorific value, up to 7000-9000 kcal per kilogram, which allows it to produce a large amount of heat during the combustion process and provide enough energy for industrial boilers.
2.Good combustion performance: Anthracite refined coal has very good combustion performance, burning quickly and completely, and will not produce too much ash and soot, which is of great help to environmental protection and energy efficiency.
3.Excellent quality: Anthracite refined coal has excellent texture, compact structure, and is not easy to break, which is very beneficial to the use and maintenance of boilers.
Second, the application of blast furnace injection.
Blast furnace injection is one of the important application areas of anthracite refined coal. By compressing the refined coal into a fine powder of 200 meshes, and then spraying it into the blast furnace through high-pressure gas, the utilization rate and combustion efficiency of coal can be greatly improved. At the same time, this injection method can also reduce the waste and loss of coal and improve production efficiency.
Third, the use of industrial boilers.
In addition to being widely used in blast furnace injection, anthracite refined coal can also be used as fuel for industrial boilers. Industrial boiler is an indispensable equipment in industrial production, which can provide hot water or steam to meet the needs of various industrial production. The high calorific value and excellent combustion performance of anthracite refined coal just meet the fuel requirements of industrial boilers.
When using anthracite refined coal as fuel for industrial boilers, the following points need to be noted:
1.Moderate air distribution: Due to the fast combustion rate of anthracite refined coal, appropriate air distribution is required to ensure the stability of combustion.
2.Control of ash content: Due to the excellent quality of anthracite refined coal, the ash content is less, but it is still necessary to pay attention to control during the use of the boiler.
3.Regular maintenance: Due to the tight texture of anthracite refined coal, the boiler may be deformed or worn out during long-term use, so regular maintenance and overhaul are required.
In conclusion, anthracite refined coal is a very high-quality coal resource with high calorific value and excellent combustion performance. Through blast furnace injection, the utilization rate and combustion efficiency of coal can be greatly improved. In the field of industrial boilers, anthracite refined coal has been widely used. During use, it is necessary to pay attention to matters such as air distribution, ash control and regular maintenance to ensure the normal operation and safety of the boiler.
