Abstract

The chemical composition and amount of waste from coal preparation plants are analyzed. The main characteristics of gasification gas under various conditions of fuel combustion are studied. The impact of the carbon content in the waste on the main characteristics of the gasification process is estimated. The analysis of the influence of various properties of the gas generated as a result of gasification on the heat engineering parameters of the process of its combustion for the needs of the consumer is carried out. The studies were carried out on the basis of a program for calculating the process of fuel combustion, waste gasification and afterburning of gasification products. Studies have shown that gasification is the most promising way to use waste from coal processing plants compared to burning. When choosing the most effective way to use the chemical energy of carboncontaining waste, it is necessary to take into account such factors as: the carbon content in the waste, the temperature of the combustion air; ratio of N 2 to O 2 in air.
