Answer: a. boiler - I. part of a coal-fired power plant.
b. combustion chamber - I. part of a coal-fired power plant.
c. condenser - III. part of a coal-fired power plant and part of a nuclear power plant.
d. control rod - I. part of a coal-fired power plant.
e. generator- III. part of a coal-fired power plant and part of a nuclear power plant.
f. turbine - III. part of a coal-fired power plant and part of a nuclear power plant.
Explanation:
a. Boiler: It is used in the coal power plant to heat the water used for producing electricity. The boiler keeps the temperature of water or steam at a desired level.
b. Combustion chamber: It is used for combustion of coal and using thermal energy for electricity generation.
c. Condenser; It is used in both nuclear and coal power plants. It condense and receive from the turbine.
d. Control rod: It is used in the nuclear power plant for controlling the nuclear fission and fusion reactions of heavy metals.
e. Generator: It converts the thermal energy into electrical energy.
f. Turbine: The turbine blades move with the effect of steam or any form of energy and the energy so produce is used for generating electricity in generator.
