Question: The diagram below shows how one type of coal is used to produce electricity.
ANSWER:
The illustration demonstrates the generation of electricity by utilizing a particular type of coal. Overall, there are eight steps in the production, beginning with mining the coal, followed by various processes to the raw material, and ending with distributing the electricity to final uses.
The first five steps involve the conversion of coal into gas, which begin with coal being excavated from a mining plant. After that, it goes through a crushing machine and is delivered by trucks to another factory, where a gasification process transforms the crushed coal into gas. Subsequently, another facility is responsible for lowering the temperature of the gas and releasing the waste heat.
The remaining steps produce electricity. Cool gas is transported to another unit for cleaning and then becomes the input for a gas power plant. While electricity is generated, excessive heat is released as a source of waste. Finally, the electricity produced from the power plant is supplied for both household and industrial uses.
