This article presents the results of thermodynamic analysis and experiments on plasma gasification of solid fuels from the example of Kuuchekinsky coal (KC). Thermodynamic calculations of plasma gasification showed that synthesis gas used in heat and power engineering, metallurgy and the chemical industry can be produced from solid fuels. Gasification (KC) allows to obtain synthesis gas with a maximum yield of 98.3% (CO - 43.5%, H2 - 54.8%).
To perform thermodynamic analysis, the TERRA software package is used, which is designed for numerical calculations of high-temperature processes and has an extensive database of its own thermodynamic properties of 3000 individual substances. The program allows you to determine the equilibrium composition of the thermodynamic system (coal + oxidizer), consisting of 20 chemical elements. The calculation is carried out automatically within the data bank created during the program. The thermodynamic data bank contains properties of more than 3000 individual substances formed by 65 elements in the temperature range 300-6000 K.
Experimental researches of plasma gasification of coal in various gasification agents were carried out at the facility, which is a cylindrical plasma reactor with systems of electricity, water, steam, gas and fuel supply.
