Development of Russian Once-Through Heat-Recovery Steam Generators for CCPPs of Various Capacities

Аннотация

The foreign experience of using once-through heat-recovery steam generators (HRSG) in CCPPs is presented. Russian developments of once-through HRSGs of various configurations based on modern gas turbines are considered. Design procedures for ensuring the reliability of the heating surfaces of high- and intermediate-pressure evaporators are developed. Technical requirements for the design of vertical and horizontal once-through HRSGs are formulated.
