The first results of testing high-capacity power gas turbine plants

In combined-cycle units that have been commissioned within recent years at Russian thermal power stations, up-to-date models of high-capacity (from 260 to 290 MW) power gas turbine units (GTUs) were installed. In their schematic diagrams and designs some engineering solutions unusual for domestic practice have been implemented. In the course of tests carried out under operating conditions, there have been obtained high efficiencies of both GTUs themselves (from 36 to 39%) and their turbine machines: compressors and turbines, low design NO x emissions at operating loads, and favorable performance characteristics in a wide range of loads and environmental conditions.
