High temperature plasma gasification of wood is evaluated for the production of a fuel gas (syngas) for combined heat and power production. The advantages of plasma by comparison with existing thermochemical processes are in the high heating value gases, process control and the lower energy consumption per unit of output. From one kilogram of 20% moisture wood it is possible to obtain 4.6-4.8 MJ of electricity (net of electricity input) and 9.1-9.3 MJ of thermal energy when using wood with average elemental composition and with a LHV energy content of 13.9 MJ, when using a combined Brayton and Steam cycle generating plant. Experimental data from an air plasma gasification plant using alternating current (AC) plasma torches was integrated with a thermodynamic model showing that the chemical energy in the produced syngas was 13.8-14.3 MJ kg-1 with a power input of 2.2-3.3 MJ kg-1. © 2010 Elsevier Ltd.

The chapter is dedicated to a promising method of biomass treatment-plasma gasification. Increased temperatures and energy supply allows significantly increase the range of wastes and other carbonaceous materials which could be efficiently processed. Features of plasma usage in updraft and downdraft biomass gasification are described. Several promising renewable energy sources (wood, energy crops, wastes of livestock, and poultry industry) are examined for the usage in downdraft plasma gasification. The correlation of key parameters of biomass plasma gasification was studied in thermodynamic equilibrium approach along with syngas usage for liquid fuel production. Institute for Electrophysics and Electric Power RAS experimental installation is described. Its primary component is a downdraft plasma gasifier for processing of biomass and wastes. Its technical characteristics and functionality are described. A brief survey of existing pilot and industrial projects is given. Methods of energy supply into plasma chemical reactor are described. The review of powerful plasma torches for industrial application is represented. Experimental procedures and test results on biomass gasification by air-plasma are presented as well as the comparison with the calculated data. © Springer-Verlag Berlin Heidelberg 2013. Source
