摘要

The paper present the results of a study for a special configuration of a combined cycle power plant. In this plant two gas turbines are installed to feed one Heat Recovery Steam Generator (HRSG). The flue gas flow in the channels between the two gas turbines and the HRSG was analyzed to get a more homogenous flow distribution in front of the first heating surface of the HRSG which is arranged downstream of the gas turbines. In the study a particular attention was placed at the operation conditions where only one gas turbine is in operation. The results of the investigation have shown that the measures with a higher possibility to get a homogenous flow distribution in front of the first tube bank arranged downstream of the gas turbine have also a higher pressure loss and in last consequence they are linked with a higher loss of gas turbine power respectively a lower efficiency of the combined cycle.
