STUDY OF PHYSICAL, MECHANICAL AND CHEMICAL PROPERTIES OF BROWN COAL
Аннотация
ABSTRACT
Currently, coal is one of the main fuels for industry, the national economy and
thermal power plants. Coal is a solid fuel that must contain enough heat to make it
economically profitable to use, as well as in the incineration of which no man-made
waste is released. In this work, the physical and mechanical properties and chemical
composition were studied, as well as the microscopic analysis and enrichment of high
ash coal by gravity method, which is mined in «Angren» section. Man-made waste that
is not recycled after the use of coal causes damage to the environment by clogging it,
but do not forget that this waste reduces the calorific value of the fuel. Thus, coals
containing various impurities do not provide effective calorific value, which increases
economic costs as well as reduces our natural wealth.
