Abstract
A gas turbine by-pass system is used between a gas turbine generator outlet nozzle and the inlet of a heat recovery steam generator (HRSG). The system allows operators to divert gasses from the HRSG in combined cycle mode to a silencer assembly to operate in simple cycle mode. The system thereby allows maintenance to be performed to the HRSG by crew of human workers without danger of an encounter with hot lethal gasses. The system includes a monorail and a series of hoists which operators use to position a blank off plate and an expansion joint as necessary with respect to the HRSG and diverter box. Consequently, the system provides for safe operation of a gas turbine in both combined cycle mode and simple cycle mode.
