Comparative study of coal plasma gasification: Simulation and experiment

• Plasma steam and air gasification of high ash bituminous coal is fulfilled.
• Availability of the high ash power coal use for high-calorific syngas production is shown.
• High integral indexes of the gasification processes were achieved.
• Syngas from the coal at steam gasification is higher quality.
• The numerical and experimental results comparison showed their satisfied agreement.

Results of complex experimental and numerical investigation of coal plasma gasification in steam and air are presented. To analyse numerically the universal thermodynamic calculation code TERRA was used. The data base of it contains thermodynamic properties for 3500 individual components in temperature interval from 300 to 6000 K. Experiments were fulfilled at an original installation for coal plasma gasification. Nominal electric power of the plasma gasifier is 100 kW and sum consumption of the reagents is up to 20 kg/h. High integral indexes of the gasification processes were achieved. The numerical and experimental results comparison showed their satisfied agreement.
