Thermodynamic calculations of a plasma gasification of municipal solid waste in air and steam mediums are fulfilled. It is shown that the maximum yield of synthesis gas at a plasma gasification of carbonaceous wastes in air and steam mediums is achieved at a temperature of 1600 K. At the developed plasma installation, experiments on gasification of the waste were carried out. From organic mass of the waste, high-calorific synthesis gas was produced and from mineral mass-neutral slag consisting mainly of iron carbide, calcium silicate, silica, and iron. Comparison between the experimental results and calculations revealed satisfy agreement.

Thermodynamic calculations of the plasma gasification process of carbonaceous wastes in air and steam ambient were carried out. A maximum yield of synthesis gas in such processes is predicted to be achieved at a temperature of 1600 K. On a specially developed plasma facility, plasma gasification experiments were performed for carbonaceous wastes. From the organic mass of carbonaceous waste and from its mineral mass, respectively, a high-calorific syngas and a neutral slag consisting predominantly of ferric carbide, calcium monosilicate, silica and iron, were obtained. A comparison between the experiment and the calculations has shown a good consistency between the data.

Numerical experiments on the torch combustion of the coal dust prepared by a plasma-thermochemical treatment for combustion have been done using the method of three-dimensional simulation. It is shown that the plasma preparation of coal for combustion enables one to optimize the process, improve the conditions for inflammation and combustion and minimize the emissions of harmful substances.
