Test: Generation in Power Plants - Electrical Engineering (EE) MCQ

As the internal energy change in the ‘Steam Power Plant’ is ZERO. Hence, the entire plant obeys a Cyclic Process.

Air- preheater in a steam power plant recovers the heat from the flue gases leaving the economiser, improves combustion rate, raises temperature of the furnace gases, etc.

The overall steam turbine generator arrangement of a power plant is designated as tandem or cross-compound on the basis of shaft orientation.

A moderator, in nuclear power plants, is a medium introduced into the fuel mass in order to slow down the speed of fast moving neutrons.

A moderator generally used in nuclear power plants is made up of graphite 

In most steam power plants, closed heaters are more favored than open heaters & so are used primarily for the purpose of feedwater deaeration.

Reflector in nuclear power plants decreases neutron leakage.

Deaerator is not used in water cooled and moderated nuclear power plant because of the concern regarding radioactivity release with deaeration.

By superposing a high temperature power plant as a topping unit to the steam plant, the energy conversion efficiency achieved is higher from fuel to electricity.

In a Steam Power Plant, the positive difference of turbine work & pump work makes it useful in electricity generation.
