Low–melting coal is a brand with a high degree of metamorphism. When burned, it forms few volatile substances, burns with a white flame. The color of the material is black, shiny; the structure is uniform, with a small number of cracks.
Low–melting coal is a brand with a high degree of metamorphism. When burned, it forms few volatile substances, burns with a white flame. The color of the material is black, shiny; the structure is uniform, with a small number of cracks. The rock is quite dense, but brittle – under impact and pressure, it quickly disintegrates into pieces.
The reserves of CC coal in Russia have so far been poorly explored. This variety is mined in the Far East, Sakhalin, Yakutia and Kuzbass. The rock lies in layers.
The main characteristics of the material:
• The carbon content is 75-90%
• Heat of combustion – 8000-8500 kcal
• Humidity – 8-9%
• Ash content – 8-45%
The main field of application of low–burning coal is energy. It is used in thermal power plants and industrial boilers. To burn the material, large furnaces and high-quality blowing are needed, without it, dense material ignites poorly and burns poorly. Therefore, this brand is rarely bought for home use.
The brand is also used as a component of the charge together with fatty coal in the production of coke. It is used in the manufacture of lime and cement.
The brand is divided into 3 groups:
• The first weak-minded (1CC)
• The second weakly perceptible (2CC)
• The third one is weakly perceptible (3 CC)
