Exhaust gases heat recovery of GPU gas turbine compressor of gas-main pipelines

Abstract

The choice of the rational heating scheme of gas turbine exhaust-gas heat utilization of main gas pipeline gas-compressor units is one of the actual problems of increasing energy efficiency of gas transportations. A number of well-known publications state that problem solution can not be considered to be completed, some results of investigation being conflicting and requiring more precise definition, taking into consideration that the processes of converting low potential heat into electric power are considerably complex. The thermodynamic efficiency and various parameter influences are also analyzed. The choice of the plant working-medium at the temperature of exhaust gases of 350-380C is explained in detail.
