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

Explanation: Natural gas and liquid petroleum fuel are among the two fuels used in a gas turbine.

Explanation: Reflector in nuclear power plants decreases neutron leakage.

Explanation: the head of water available at turbine inlet in hydro-electric power plant called Net Head.

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

Explanation: The auxiliary equipment in a power plant are those equipment which are driven by the electricity taken from the generated power of the plant.

Explanation: A moderator generally used in nuclear power plants is made up of graphite & concrete.

Explanation: The most common size steam power plant is of 500 MW(e). Further large size plants have been built, but aren’t found in common usage.

Explanation: 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.

Explanation: The investment cost in Conventional steam power plant is 30% more than those in the combined cycle plants.

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

Explanation: Oxides and hydroxides of seeding element formed cause air pollution.

Explanation: 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.

Explanation: Spray ponds are used to cool the warm water coming from the condenser in small power plants.

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