SOME ASPECTS OF DEVELOPMENT AND CREATION OF PLASMA TECHNOLOGY FOR SOLID WASTE GASIFICATION

Abstract

According to evaluations of world specialists in the field of power engineering the share of energy generated from the renewable sources by 2010 in the developed countries can make up to 10 % from consumed. Already accumulated and continuously increasing volumes of various organic wastes are among these sources, which fuel use serves for simultaneous solution of two problems: ecological and power. In this connection the most promising are the technologies permitting not only neutralizing and reducing waste volumes, but also complete transforming the contained energy to electricity and heat. Active theoretical and practical work on creation of such technology is recently carried out in IEE RAS. The paper deals with the basic stages of the installation creation for gasification of 50÷100 kg /h of solid waste with application of AC plasma torches. Process outcome is synthesis gas containing by calculated estimations of 50−70 % CO and H2 mixture and having combustion heat of 6−10 MJ/m3. Some design variables and estimations, structural features and functionalities of the installation are discussed. Initial experimental data are represented.
