[Task 1] Process: Electricity from fossil fuels

Hình ảnh thuộc về IELTSCompanion

The given image depicts how electricity is produced using fossil fuel.

Overall, there are four main stages in the generation of electricity: burning of coal, producing purified syngas, operating turbines, and creating electricity.

First of all, coal is led into a furnace where it is burned in an oxygen-rich environment. This process creates syngas and slag as a waste. The raw syngas then goes through a process to remove impurities such as CO2, Mercury and Sulphur. Purified syngas is then used to rotate a gas turbine, which operates a generator to produce electricity. The hot exhaust gas from the turbine is then collected in a heat recovery steam generator system where it is broken down into steam and flue gases. The flue gases are released into the air while the steam travels into a steam turbine to run another generator and produce energy. All the electricity from these processes enters the national power grid.\
