Gas turbine and gas-vapor units with ceramic modules

The problems of structural ceramic materials application for the high temperature uncooled flow paths of gas turbine units (GTU) at their autonomous operation and as a part of the combined cycle plants with recovery boiler, are discussed. The main features of thermodynamic analysis for optimization of thermal diagrams and cycles, are shown. A requirement of block-module approach to build up the GTU design schemes as well as an expediency to use a cycle with air intercooling in the compression process, are described. A feasibility to raise the thermal stations effectiveness by 15...18%, is defined.
