【摘要】：以Kalina地?zé)岚l(fā)電循環(huán)(KCS11)為研究對象,針對冷熱源溫度、工質(zhì)濃度比及循環(huán)壓力等參數(shù)的變化對KCS11循環(huán)效率的影響進(jìn)行研究�；贓ngineering Equation Solver(EES)工程軟件平臺,編寫KCS11運行參數(shù)的計算模型。模擬結(jié)果與文獻(xiàn)中的數(shù)據(jù)進(jìn)行對比,擬合程度較好。進(jìn)一步研究表明,系統(tǒng)運行中氨水濃度應(yīng)略高于最高效率點所對應(yīng)的濃度值,且系統(tǒng)壓力應(yīng)等于或略大于最高效率所對應(yīng)的壓力值。通過對冷熱源溫度、濃度、壓力等參數(shù)分析,熱源溫度升高或冷源溫度降低10℃,系統(tǒng)循環(huán)效率可提高2.0%~3.5%。在特定冷熱源溫度下,當(dāng)氨水濃度增加0.10,循環(huán)最大效率所對應(yīng)的壓力增大0.8 MPa,系統(tǒng)泵耗隨之增加,故系統(tǒng)效率存在極值點。因此在系統(tǒng)運行中應(yīng)考慮氨水濃度與系統(tǒng)壓力的匹配,保證系統(tǒng)能夠高效運行。
