Abstract:

利用ASPENPLUS稳态模拟平台测试修正热力参数、流动过程的作用条件,以建立冷热电联供(CCHP)系统的联合循环,研究了系统中关键单元的热功转换过程,以及物流的流率、压力和温度分布,探讨了各输入参数对系统经济、技术和排放性能等的影响。结果表明:(1)预设工况下,燃气轮机进口温度为340℃,系统总能利用率达到94.65%,经济效率达到67.27%,CO2、CO、NO2、NO、SO2排放量分别为0.5kg·(kW·h)-1、1.025mg·(kW·h)-1、0.15g·(kW·h)-1、6g·(kW·h)-1、3.7g·(kW·h)-1;(2)随着空气流量的增加,燃气轮机和余热锅炉的排气温度急速下降,总能利用率上升,而相对节能率、当量效率和经济效率不断减小。因此,空气的量应控制在理论空气量的20%~40%之间;(3)随着空气温度及环境温度的升高,燃料的气化率会微小地下降,但系统的总体能效性能会提高。
