三压力氨水动力循环的热力学分析
, PP. 54-58
Keywords: 氨水混合工质,三压力,动力循环,卡林纳循环,溶液浓度,热力性能
Abstract:
在卡林纳循环基础上增设1个预热器和1个水冷溶液冷却器而构成的三压力氨水动力循环（tpawpc），能更合理循环能量，节省换热面积，且可生产生活热水。在循环热效率ηth基础上，考虑余热回收率ηwh，选取两者的乘积（动力回收效率η0）作为评价准则，模拟计算分析了工质工作浓度和基本浓度、循环倍率、透平进口温度等循环重要参数对循环热力性能的影响。结果表明，工质的工作浓度决定了循环工作压力，工质基本浓度必须与工质工作浓度相配合方可获得高效率；循环倍率对循环动力回收效率呈正向较弱影响；当透平进口工质参数为400℃/8mpa，循环最低温度为30℃时，循环热效率和动力回收效率分别为26.05%和22.47%。
