Regeneration of the Heat of Exhaust Gases in Gas Turbine Plants that Function in Simple and Compound Cycles

Resumo

It is shown that the efficiency of the regenerative cycle may be increased while simultaneously increasing the degree of increase of pressure in a compressor and the degree of regeneration. For this purpose, we consider gas turbine plants that function in simple and compound cycles with intermediate air cooling in the compressor and its further warming in a regenerative heat exchanger with the use of the technique of regeneration of the heat of the waste gases in the turbine. Graphical relationships are constructed for use in determining the optimal degree of increase of pressure and degree of regeneration accompanied by an increase in the effective efficiency of the gas turbine plant cycle.
