| 英文摘要 | The contribution of mid-temperature solar thermal power to improve the performance of coal-fired power plant is analyzed in the present paper. In the solar aided coal-fired power plant, solar heat at <300 degrees C is used to replace the extracted steam from the steam turbine to heat the feed water. In this way, the steam that was to be extracted could consequently expand in the steam turbine to boost output power. The advantages of a solar aided coal-fired power plant in design condition have been discussed by several researchers. However, thermodynamic performances on off-design operation have not been well discussed until now. In this paper, a typical 330 MW coal-fired power plant in Sinkiang Province of China is selected as the case study to demonstrate the advantages of the solar aided coal-fired power plant under off-design conditions. Hourly thermodynamic performances are analyzed on typical days under partial load. The effects of several operational parameters, such as solar irradiation intensity, incident angle, flow rate of thermal oil, on the performance of solar field efficiency and net solar-to-electricity efficiency were examined. Possible schemes have been proposed for improving the solar aided coal-fired power plant on off-design operation. The results obtained in the current study could provide a promising approach to solve the poor thermodynamic performance of solar thermal power plant and also offer a basis for the practical operation of MW-scale solar aided coal-fired power plant.
