Analysis of the possibility of increasing thermal-electric energy conversion ratio in CHP units based on micro gas turbine

Abstract

The aim of this paper is to analyze the possibility of increasing thermal energy to electricity conversion efficiency in combined heat and power (CHP) units based on micro gas turbine during low heat demand periods. At the beginning sustainable development postulates under power engineering are explained. Next micro CHP as part of distributed generation idea is presented. The main part of the article is based on results of thermodynamic and preliminary flow calculation for micro steam turbine cooperating with Capstone C200 micro gas turbine. An analysis of ’hot beginning’ and ’cool end’ of the turbine parameters due to flow limits is carried out. The ending contains a summation of the calculation results and a conclusion about combining steam and gas micro generating units.
