This paper presents the analysis of ecological and economical availability for using syngas from gasification of biomass waste or other solid fuels into diesel with ICE-based combined cycle (CC). The new approach is proposed to improve the ecological efficiency of the CC system and decrease the cost of electricity which can be produced with electric generator. For optimization of design of the combined system the new diagrams were obtained to determine characteristics of mixed fuel (diesel + syngas) for the engine at varied syngas fuel parameters after the gasifier with steam agent (plasma or other type). Based on these diagrams it is possible to obtain total reducing CO2 emission in atmosphere of ~1.5 times in the CC system with biomass gasifier.
KeywordsBiomass waste gasification gas Combined cycle Ecological efficiency Thermal and chemical recuperation Transformation of exhaust gas into combustible syngas Reducing CO2 emission
