摘要
针对广州某纺织厂设计一套1 t/h热负荷的太阳能-锅炉联合蒸汽系统,建立系统的热力学模型和基于TRNSYS软件的仿真模型,并以太阳指数、集热效率及太阳能保证率等参数为指标对系统进行模拟研究。结果表明:所设计的系统及控制方式在不同时刻所产生的蒸汽量可以满足负荷需求;系统月均太阳指数最高为38%,全年月均集热效率最高为43%,11月份太阳能保证率最高为26%,该系统每年可减少CO2排放量235 t,节省天然气12万m3,相当于节约160 t标准煤,具有良好的经济和环保效益。
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.
