The process of generating electricity from coal using gasification technology

The provided diagram illustrates the industrial process of converting coal into electricity. Overall, the procedure is a linear sequence that begins with raw material preparation and culminates in power distribution, involving several intermediate stages of chemical and thermal conversion.

Initially, coal is extracted and processed through a crusher to reduce its size. Once crushed, the coal is transported to a gasifier. During this gasification stage, heat is produced as a by-product. The resulting gas is then directed to a cooling unit, where further waste heat is released. Following the cooling phase, the gas undergoes a cleaning process to ensure it is suitable for power generation.

In the final stages, the cleaned gas is fed into a gas power plant. This facility converts the gas into electricity, which is then distributed to industrial consumers and the national power grid. Similar to the gasification and cooling stages, the power plant also emits waste heat as a secondary output. The entire cycle highlights the complexity of coal-based energy production, emphasizing both the primary objective of electricity generation and the inevitable release of thermal energy throughout the various conversion steps.
