The diagram illustrates the process of generating electricity from coal through gasification. The procedure consists of multiple stages, including crushing, gasification, cooling, cleaning, and power generation.
Initially, raw coal is fed into a crusher, which breaks it down into smaller fragments. While some of this crushed coal is transported away, the rest is transferred to a gasifier, where it is heated to produce synthetic gas (syngas). This gas then undergoes a cooling process, during which excess heat is expelled.
Following this, the cooled gas moves to a cleaning facility, where impurities are removed. The purified gas is then delivered to a gas power plant, where it is burned to produce electricity. The generated power is subsequently distributed to factories and the electrical grid. However, the process also generates additional waste heat, indicating some energy loss.
Overall, this method of electricity generation relies on gasification rather than direct combustion, making it potentially more efficient. However, the loss of heat at multiple stages suggests opportunities for further energy optimization.
