摘要：
A solar-boiler combined steam system was designed for a textile mill in Guangzhou with 1 t/h steam thermal load. The thermodynamic model of the system and the simulation model based on TRNSYS software were established. The system was simulated and evaluated by the parameters of solar fraction, heat collection efficiency and solar guarantee rate, etc. The simulation results show that the amount of steam generated at different times by the designed system and its control method can meet the load demand. The maximum monthly average solar fraction of the system is 38%, the highest monthly average heat collection efficiency is 43%, and the highest solar energy guarantee rate is 26% in November. The system could reduce CO2 emissions by 235 t per year and save natural gas by 120,000 m3, equivalent to saving 160 t of standard coal, which has good economic and environmental benefits. © 2020, Solar Energy Periodical Office Co., Ltd.
