4 FAQs about The generator of the power station needs to be preheated

How does a power station turn a generator?

Power Stations Turning a generator produces electricity. To turn the generators we connect them to turbines. We use different energy resources to turn the turbines. Wind and water flow can turn turbines directly. Steam is often used, produced by heating water. The heating is done by burning fuels, or using other heat sources.

Why is pre-heating a power plant a problem?

Most power plants have several steam turbines and at least one is always running. It means that there is always steam available for the pre-heating. The usage of the steam from an external source is related to several issues that make the pre-heating process problematic. First of all the pre-heating system involves two power generating units.

How does a power station generate electricity?

Steam moves a turbine, turning an electric generator. This electricity is then supplied to the grid. Describe step by step, the different components involved in electricity generation in a power station. Fuel burned → Water heated → Turbines turn → Electrical generator turns → Electricity produced.

How does pre-heating a steam turbine work?

This procedure may begin at the same time the boiler is started. Secondly the pre-heating raises the turbine temperature above the standard level. When the valves are open and the live steam is delivered to the turbine for the first time the turbine temperature is already quite high. The rate of the temperature increase may be higher.
