The provided diagram illustrates the conversion of coal into electricity through a series of interconnected stages within specific facilities.
The process involves a total of 10 sequential steps, starting from coal extraction in the mine to the distribution of electricity to different locations.
Initially, coal is excavated from underground mines and then subjected to crushing to facilitate combustion and transportation to the gasifier by trucks. Subsequently, the coal particles are converted into gas through heating in the gasifier and then cooled in a separate cooler, with waste heat being discharged. The cleaned gas is then directed to the gas power plant for electricity generation, thereby producing excess heat as a byproduct.
Finally, the electricity generated is supplied to households and industries for various applications. It is noteworthy that the cooling process generates solid waste as depicted in the diagram, emphasizing the comprehensive nature of the electricity production from coal.
