Abstract:To promote the development of solar thermal energy and reduce the coal consumption of coal-fired units,a tower-type solar thermal system equipped with heat storage is coupled with coal-fired units.The solar heat is designed to be 30 MW,and Eblison modeling is used to conduct thermodynamic analysis of the system.Studies show that under the 50%THA working condition,the coal-saving effect is the best,and the standard coal consumption rate is reduced by 15.56 g/kWh.Under the 100%THA condition,the solar power generation capacity and photovoltaic efficiency are the highest,which are 10.17 MW and 17.9%,respectively,providing a reference for the variable condition performance research of tower-type solar-assisted coal-fired power generation systems.
