Band 5+: You should spend about 20 minutes on this task. The diagram below shows how one type of coal is used to produce electricity. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. You should write at least 150 words.

The process by which one type of coal is used to produce electricity can be outline in nine consecutive steps.Overall this linear procedure starts with extracting the coal from the mine , followed by treating it a crusher, and finishes with the transportation of ready coals into electricity.The

Process is a complex one , which requires much time and equipment to complete.

Everything in procedure commences with the excavation of coals from the ground with the assistance of specialized machine. The dig coal is then sorted in the metal grid to break into smaller pieces, which then go through another apparatus called a crusher.Subsequent to this ,crushed coal dispatched to the gasifier where coal is converted into gas using heat

Then , the ready coals are cooled in the cooling factory. The next phase sees cleaning where impurities are removed from the gas.The ultimate step is the gas power plant , clean gas is burned to electricity. Ultimately, the ready coals are dispatched to electricity companies.
