Popis:	The chemical composition and the amount of waste from coal preparation plants are analyzed. The main characteristics of the gasifying gas under various conditions of fuel combustion are studied. The impact of the carbon content in 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 software for calculating the process of fuel combustion, waste gasification and gasification products afterburning. Studies have shown that gasification is the most promising way of using waste from coal preparation plants compared to burning. When choosing the most effective way to use the chemical energy of carbon-containing waste, it is necessary to take into account such factors as: the carbon content in the waste, the heating temperature of the combustion air, the ratio of N2 and O2 in the air.
