The diagram illustrates the process by which electricity is generated from coal.
Overall, electricity production involves several stages, beginning with coal mining and ending with the distribution of electricity to homes and industries. During this process, both solid waste and heat waste are produced as by-products.
Initially, coal is extracted from a mine and then crushed into smaller pieces. After that, the crushed coal is transported to a gasifier, where it is converted into gas. Solid waste is removed at this stage. The gas produced is subsequently cooled before being delivered to a gas power plant.
In the final stage, the gas power plant uses the processed gas to generate electricity. This electricity is then supplied to residential areas and industrial users. However, heat waste is released during electricity generation, indicating an unavoidable loss of energy in the system.
