EVALUATION OF EFFICIENCY OF THERMOCHEMICAL HEAT RECOVERY IN DIESEL-GAS TURBINE POWER PLANT

Abstract

This article discusses efficiency of thermochemical heat recovery of waste heat in energy complexes. Some results of research have been shown. The main aim of the research is the enlarged analysis of interrelations of thermodynamic properties of gas turbine plant with the thermochemical heat recovery and internal-combustion engine specification which operates on the conversion of fuel. At the mathematic simulation the efficiency of conversion was estimated with the magnification factor of the calorific value. The heat balance of the thermochemical reactor determined the heat input of exhaust gases. The specific fuel oil consumption was resolved as the efficiency criterion of the unit. The analysis of the temperature potentials of waste heat of the medium speed diesel engine and gas turbine engine is provided. A scheme of combined diesel-gas turbine power plant with the thermochemical heat recovery of exhaust gases with the steam conversion of hydrocarbon fuel is considered. The efficiency of this scheme in operation on different fuels is determined. The results of research may be used in the development of power plants of mobile and stationary facilities. It is determined that the ethanol and butane conversion is the most effective for the disposable temperature range of exhaust gases of modern commercial gas turbine engines.
