CRITERION TO EFFECTIVE OF GAS TURBINE OF COMPLEX CYCLE WITH INTERMEDIATE HEATING AND FREE TURBINE

Abstract

It is shown physical sense and is given theoretical reason of increase effective efficiency gas turbine of complex cycle with intermediate heating in compare with gas turbine of simple cycle by use of maximum of degree reduction of pressure in free turbine as criterion to effective. Increase of effective efficiency of gas turbine of complex cycle is considered in interval of increase degree increase of pressure in cycle from corresponding to maximum of degree reduction of pressure in free turbine gas turbine of simple cycle before corresponding to absolute maximum of this parameter in gas turbine of complex cycle. It is shown physical sense of degree increase of pressure, corresponding to absolute maximum offered criterion to effective.
