The diagram illustrates the production of electricity converted from coal. Overall, the procedure consists of multiple connected stages, commencing with coal mining and ending with electricity distributed for households and commercial buildings. In addition, waste heat is a by-product forming during two stages of this process. The production started with coal collection by mining at the coal sites. The collected coal then is crushed into small pieces by crusher, after which the bits are transported to another place and heated to produce gas. Following this stage, the gas is cooled down in a factory. During this procedure, waste heat is also generated. Subsequently, the cooled gas continues to experience the cleaning process in another factory. Finally, the gas is delivered to a gas power plant, where the gas is converted into electricity allocated to households and industrial buildings for use. Besides, the waste heat is generated along the electricity during this process, too.
