Abstract

A process arrangement for improving the energy efficiency of combined heat and power plants (CHPPs) using absorption heat transformers (AHTs) is considered. The aim of the study is to improve the energy efficiency and environmental friendliness of using natural gas in power supply systems by applying steam turbine plants and absorption heat transformers.

For modeling the modernization of a CHPP and for estimating the dispersion of harmful emissions, the ISC Manager and the Thermoflex software systems were used. All calculations were carried for one power unit of the CHPP-21 in Moscow. The obtained data on improving the energy efficiency and decreasing harmful emissions were extended for the entire power system of Moscow, in which the CHPPs operated by PJSC Mosenergo serve as the main source of heat and electricity.

The applied computer programs are described, and the energy and environmental effect from the modernization of one power unit, one CHPP and the entire power system of Moscow has been estimated in a first approximation.
