HRSG BOILER BY-PASS STACK

Products Information

Bypass stack is the important component of HRSG boiler.

A gas turbine bypass system is designed to divert the flue gases from the HRSG to a bypass stack with a silencer assembly to allow the plant to operate in simple cycle mode.

This allows the HRSG to be inspected, repaired, or has maintenance performed while it is isolated completely from the gas turbine.

Using a bypass stack also allows for combined cycle operation during the day and simple cycle operation at night when power demand is lowest, providing a greater savings in operation cost and efficiency over the life of the power plant.

The bypass stack and diverter system permits power to be generated by the gas turbine even when the steam turbine cycle is down for a scheduled or unscheduled shut down, keeping the plant functional and avoiding potential power outages.
