Question 437

In a steam-electric power station using fossil fuel (such as coal), chemical energy is released to eventually produce electrical energy.

In which order is the energy transferred through the components of the power station?

A

coal→generator→boiler→steam turbines\text{coal} \rightarrow \text{generator} \rightarrow \text{boiler} \rightarrow \text{steam turbines}coal→generator→boiler→steam turbines

B

coal→boiler→generator→steam turbines\text{coal} \rightarrow \text{boiler} \rightarrow \text{generator} \rightarrow \text{steam turbines}coal→boiler→generator→steam turbines

C

coal→boiler→steam turbines→generator\text{coal} \rightarrow \text{boiler} \rightarrow \text{steam turbines} \rightarrow \text{generator}coal→boiler→steam turbines→generator

D

coal→steam turbines→boiler→generator\text{coal} \rightarrow \text{steam turbines} \rightarrow \text{boiler} \rightarrow \text{generator}coal→steam turbines→boiler→generator
