Combined Cycle Power Plant operators are under constant pressure to increase on-line availability. One of the most critical systems to facilitate this undertaking is the Steam Turbine Bypass System. Commonly used for startup, shutdown, and steam turbine trips, as plants are more frequently cycled, these systems are often being called-on to perform in low load and simple cycle operations

Steam turbines can be found in almost any processing plant or power generation facility. In processing plants, steam turbines are used as the driver for other rotating equipment, converting thermal energy to rotational energy ultimately to control input speed of a driven device.

Whether a combustion turbine is installed as a simple cycle peaking unit, or in a combined cycle plant with a Heat Recovery Steam Generator (HRSG), it is an integral part of the power generation portfolio for many generation companies.

Keeping accurate and stable drum level control is vital to optimal plant operation, but there are many challenges that are inherent with this process. Innate to level control on a drum style boiler is a dynamic called “shrink and swell”, which is caused by the formation of vapor bubbles in the boiler evaporation tubes as steam demand changes.

Specific to the design and piping layout of every plant is a Net Positive Suction Head (NPSH) available for a boiler feed pump. This defines the inlet pressure at the suction side of the pump, due to the effects of gravity and system design.

Attemperators have been a key component of Combined Cycle Power Plants for many years. Back when the units were base loaded, spray water control was a non-issue. In today’s world, plants are ramping up and down daily, putting a strain on steam temperature control regulation.
