Can the heat generated by thermal power plants be reused?

Yes, but the cost is too high. My personal design is to pass the generated hot air into the pressurization device first, then the fast high temperature airflow drives the turbine to produce electricity (you can also add water to the medium to absorb heat and use water vapor to drive the turbine, but you need to calculate and compare the energy conversion efficiency. It is too complicated and practical. In fact, just like the flame of a rocket, the hot gases generated by a thermal power plant take away some of the energy. From a long-term perspective, secondary use significantly improves the use of. energy.
