Title: Sky-vent system from Emerson insures temperature control of turbine during startup

Valves within the sky vent system of a combined cycle plant serve one of the more important control functions. During initial operation of the HRSG, these valves bypass steam (HP/HRH/LP) around the steam turbine to ensure that the unit doesn't come up to temperature too quickly. This is done as the process lines are warmed prior to admitting steam through the turbine bypass valves that dump to the condenser.
