Abstract

The upgrading technology for hot gas path(AGP) components of GE's PG9351 FA gas turbine is introduced. On the basis of the actual situation of a combined cycle power plant(CCPP)

the retrofitting principle and scheme for the AGP upgrading are analyzed and proposed

and the corresponding change of the CCPP's thermal performance

investments and earnings are also evaluated. The results show that

the AGP upgrading for the PG9351 FA gas turbine can improve the CCPP's power output and thermal efficiency. The AGP upgrading has good economic benefits and a short payback period. Moreover

it suggests that necessary check computations

inspections and tests should be carried out on the key accessorial equipments before the retrofitting is carried out

so as to make the most suitable transformation scheme.
