the diagram illustrator the posses of generating electricity from coal.
Overall, the diagram starts with coal extraction and ends with presenting electricity in power lines in two general prats. First the consumption of coal and second how water generates electricity by using coals energy.
At first coal is extracted from coalmine and broth to factory to be crash in a pulverize. Then its transfer to furnace to be burned down. Coals burning produces heat to make hot water for the next steps of the process.
For the next step cold water is transferred to furnace with a plump to increase the temperature of it. After that hot water is entered in to a storage with a turbine. the turbine rotates due to water energy and generates electricity. In the text stage water is broth back to a cooler to recycle the process over and electricity is sent to power lines.
