Abstract
The results of the study of the composition and characteristics of high-ash brown coal of the Angren deposit, used in the power industry of the Republic of Uzbekistan are presented. A feature of this coal is the presence in the composition of the fuel of various clay rocks that fall during mechanized mining from the surrounding rocks. Dependencies have been determined showing the effect of the composition of the fuel and the parameters of its characteristics on mechanical, chemical and thermal processes, as well as on the chemical composition of brown coal ash.
Highlights
In the fuel balance of the republic, the share of brown coal in question is about 5%
To carry out research work to improve the quality of the coal in question, it is necessary to carry out research work to determine its composition and characteristics using modern methods and laboratory equipment
The main characteristics of the brown coal under consideration include the following, reflecting its quality, parameters of the heat of combustion, humidity, ash content, sulfur content, the yield of volatile substances and others, where the main indicator is the heat of combustion
Summary
In the fuel balance of the republic, the share of brown coal in question is about 5%. The Angren and NovoAngren thermal power plants are coal-fired. To carry out research work to improve the quality of the coal in question, it is necessary to carry out research work to determine its composition and characteristics using modern methods and laboratory equipment
