The diagram shows the process of how coal can be used to generate power. Overall, we can see a clear step by step format that shows every detail, starting with raw coal, and necessary intermediate steps, then reaching the final result of newely generated electricity.
The process begins with the gathering of raw coal, which is then sent to the specifically designed machinery located in the factory, in order to be crushed. Then it is transported using by a pickup truck all the way to the gasifier which helps in releasing heat. After that the gas is taken to the intriguinly facinating cooling zones, were it will be cooled and any waste heat will be released. Furthermore, it is then sent for cleaning and finally to the gas power plant which again releases any form of waste heat, and leads us to the final result, the generation of electricity, which can be used for multiple different enviromently beneficial uses.
In summary, the diagram illustrates a clear understanding of how a naturally formed phenomena such as coal can be used to benefit us in the present time.
