The diagram below shows the process of generating electricity from coal. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
The diagram illustrates how electricity is generated from coal.
Overall, the process has nine stages, beginning with the supply of coal and ending with the disposal of ash.
First, the supply of coal goes into a pulverizer, a machine which breaks the coal into powder. Then, the dust from pulverizing the coal is collected before it enters the boiler and it is collected in a stack for emission. The powder, however, is burned and it is used to heat water in a boiler, to produce steam. Next, steam from the boiler enters a pipe which connects with a turbine. The steam drives the turbine which spins a generator to create electricity in the substation/transformer.
Ash from burning the coal dust is collected from the boiler, ready for disposal. The steam used to drive the turbine is then cooled, and it is condensed back into water using a cooling system. Finally, this water is returned to the boiler and the process begins again.
