This paper proposes a tower solar aided coal-fired power generation (TSACPG) with a thermal energy storage system.
Tower solar energy can be integrated into coal-fired power plants to improve the utilization level of solar energy, as it can heat the working medium to more than 500 ℃. Research on the use of tower solar energy in this context is worthwhile.
Solar Power Towers (SPT), also denominated Central Receiver Systems (CRS), are set up by a heliostats field which reflects solar radiation into a central receiver located atop a tower. These heliostats track the Sun with two axis. They are also considered as point focus collectors.
2.3. Thermo-economic data Regarding efficiency values and as a general overview, it can be highlighted that thermal efficiency (solar to mechanical) is estimated between 30% and 40% for solar power towers.
Solar power towers have the potential for storing much more heat than parabolic trough collectors . Nevertheless, some key challenges must be addressed in order to become a real option for storing energy in large power capacity plants with low electricity costs in the near future .
Extensive literatures have indicated that the better the higher-grade extraction steam is replaced by solar energy, the improved thermal performance would be in a tower solar aided coal-fired power plant. Therefore, the saved extraction steam from high-pressure cylinders continues to expand in the turbine to generate power.
