power station boiler control system applications

Study Of PLC & SCADA Controlled Thermal Power Plant

In boiler the control parameters are temperature control, pressure control, and water level control. These parameter are control by temperature sensor, float switches and pressure sensors .Temperature sensors are used to sense the variation in the temperature. Temperature sensor is passive element.

Gas Turbine Power Plant | Electrical4U

Dec 30, 2018 · The constant loss is quite smaller in gas turbine power plant compared to a steam turbine power plant because in the steam turbine power plant boiler has to run continuously even when the system does not supply load to the grid. A gas turbine power plant can more instantly be started than an equivalent steam turbine power plant.
