RESUMO

This paper presents a numerical analysis and experimental investigation of two very different solid fuels: low-rank bituminous coal with 40% ash content and petrocoke with 3% ash content, gasification under steam and air plasma conditions with the aim of producing a synthesis gas. The numerical analysis was fulfilled using the software package TERRA for equilibrium computation. Using the results of numerical simulation, experiments on plasma steam gasification of the petrocoke and air and steam gasification of coal were conducted in an original installation. The nominal power of the plasma installation is 100 kWe and the total consumption of reagents is up to 20 kg/h. A high-quality synthesis gas was produced in the experiments on plasma gasification of solid fuels. It has been found that the synthesis gas content at about 97.4 vol.% can be produced. Comparison of the numerical and experimental results showed satisfactory agreement.
