锅炉水蒸气的焓熵图及其使用说明

锅炉水蒸气的焓熵图及其使用说明本节概要 水蒸气不能作为理想气体处理～对蒸气热力性质的研究～包括状态方程式、比热容、热力学能、焓和熵等参数目前还难以用纯理论方法或纯实验方法得出能直接用于工程计算的准确而实用的方程。现多采用以实验为基础～以热力学一般关系式为工具的理论分析和实验相结合的方法～得出相关方程。这些方程依然十分复杂～仅宜于用计算机计算。为方便一般工程应用～由专门工作者编制出常用蒸气的热力性质表和图～供工程计算时查用。 本节介绍了由我国学者编撰的水和水蒸气热力性质表和h-s图及确定水和水蒸气热力性质的计算程序～考虑到我国的国情两者不应偏废。 本节内容 2.8.1 国际水蒸气骨架表和IFC公式 2.8.2 水蒸气表 2.8.3 水蒸气的焓熵图 2.8.4 水和水蒸气性质计算机程序简介 2.8.5 例题 本节习题 2-13、2-14 水蒸气的焓熵图 利用水蒸气表确定水蒸气状态参数的优点是数值的准确度高～但由于水蒸气表上所给出的数据是不连续的～在遇到间隔中的状态时～需要用内插法求得～甚为不便。另外～当已知状态参数不是压力或温度～或分析过程中遇到跨越两相的状态时～使用水蒸气表尤其感到不便。为了使用上的便利～工程上根据蒸汽表上已列出的

各种数值～用不同的热力参数坐标制成各种水蒸气线图～以方便工程上的计算。除了前已述及的p-v图与T-s图以外～热工上使用较广的还有一种以焓为纵坐标、以熵为横坐标的焓熵图,即h-s图,。水蒸气的焓熵图如图2-9所示。图中饱和水线x =1的上方为过热蒸汽区,下方为湿蒸汽区。h-s图中还绘制了等压线、等温线、等干度线和等容线。在湿蒸汽区～等压线与等温线重合～是一组斜率不同的直线。在过热蒸汽区～等压线与等温线分开～等压线为向上倾斜的曲线～而等温线是弯曲而后趋于平坦。此外～在h-s图上还有等容线,图2-9中未画出,～在湿蒸汽区中还有等干度线。由于等容线与等压线在延伸方向上有些近似,但更陡些,～为了便于区别～在通常的焓熵图中～常将等容线印成红线或虚线。 图2-9水蒸气的h-s图

饱和水蒸汽压力与温度密度蒸汽焓汽化热的关系对照表

饱和水蒸汽压力与温度、密度、蒸汽焓、气化热的关系对照表 一.什么是水和水蒸气的焓? 水或水蒸气的焓h，是指在某一压力和温度下的1千克水或1千克水蒸气内部所含有的能量，即水或水蒸气的内能u与压力势能pv之和(h=u+pv)。水或水蒸气的焓，可以认为等于把1千克绝对压力为兆帕温度为0℃的水，加热到该水或水蒸气的压力和温度下所吸收的热量。焓的单位为“焦/千克”。 (1)非饱和水焓：将1千克绝对压力为兆帕温度为0℃的水，加热到该非饱和水的压力和温度下所吸收的热量。 (2)饱和水焓：将1千克绝对压力为兆帕温度为0℃的水，加热到该饱和水的压力对应的饱和温度时所吸收的热量。饱和温度随压力增大而升高，因此饱和水焓也随压力增大而增大。例如：绝对压力为兆帕时，饱和水焓为 x 103焦/千克;在绝对压力为兆帕时，饱和水焓则为 x 103焦/千克。 (3)饱和水蒸气焓：分为干饱和水蒸气焓和湿饱和水蒸气焓两种。干饱和水蒸气焓等于饱和水焓加水的汽化潜热；湿饱和水蒸气焓等于1千克湿饱和蒸汽中，饱和水的比例乘饱和水焓加干饱和汽的比例乘干饱和汽焓之和。例如：绝对压力为兆帕时，饱和水焓为 x103焦/公斤；汽化潜热为1328 x103焦/公斤。因此，干饱和水蒸气的焓等于： x103+1328x103= x 103焦/千克。又例如:绝对压力为兆帕的湿饱和水蒸气中，饱和水的比例为,(即湿度为20%)干饱和水蒸气比例为(即干度为80%)，则此湿饱和水蒸气的焓为 x103 x 十 = x 103焦/千克。 (4)过热水蒸气焓：等于该压力下干饱和水蒸气的焓与过热热之和。例如：绝对压力为兆帕，温度为540℃的过热水蒸气的干饱和水蒸气的焓为 x 103焦/千克，过热热为 x 103焦/千克。则该过热水蒸气的焓为: x 103+ x 103= x 103焦/千克。
