对流受热面换热
heat transfer at convection heating surfaces

  dUll一U Sh0Urem一on hU0nre对流受热面换热(heat transfer at。onveetionheating surfaees)热量由受热面一侧的热流体以对流方式传给另一侧的冷流体的过程。锅炉对流受热面换热计算的基本方程为换热方程式和热平衡方程式。 换热方程式换热过程中对流受热面传递的热量Q与冷、热流体间的平均温差山和受热面积H成正比,换热方程式可写成:Q~KH山,kJ/h。锅炉对流受热面的换热计算.通常以每千克燃料为基准,因此换~~一、__一一、,_KH山,,,.、._热方程式又可表示为:Q~竺若竺,kJ/kg,式中药n‘~’协~~J~“’/子’伟B,’.”’吧’~’一J为锅炉计算燃料消耗量,kg/h;其余各项分别介绍如下. (1)传热系数K〔kJ/(m,·h·℃)]:表示温差为1℃、受热面积为lm2条件下每小时的传热量。对于锅炉中常见的各种光滑管受热面的传热系数均可用多层平壁的传热系数公式来表示:1.氏一十六尸十“1匆 民‘1+~护‘十— 人aZkJ/(mZ .h.℃)l一人一凡式中a,和aZ为加热介质对管壁和管壁对受热介质的换热系数;a,和入为管子外表面上灰垢层的厚度和导热系数;占,和人,为管壁的厚度和导热系数;氏和人为管子内表面上水垢层的厚度和导热系数。烟气对管壁的换热系数al可写成:a,一右(久十ar),式中ac和a,为对流换热系数和辐射热系数;泞为利用系数,它是考虑由于烟气对受热面冲刷不完全而使吸热减少的修正系数。ac与许多因素有关:如气流的速度和温度、一定的线性尺寸、管子布置方式、受热面种类、烟气流经受热面的性质(纵向流、横向流或斜向流)以及流通介质的物理性质等。ar与烟气流的温度、黑度及受热面外壁温度、黑度有关。综上所述,传热系数是一个与过程有关的物理量,其值取决于参与换热的两种流体的物理性质、运动状态、受热面的结构形式及布里方式等。 (2)温差山(’C):参与换热的两种流体在整个受热面中的平均温差。温差大小与两种流体相互间流动方向有关。如果一种流体的温度在受热面范围内保持不变,则温差与两种流体相互间的流动方向无关。冷、热流体彼此反向平行流动的受热面连接方案,称为逆流,而彼此同向平行流动的,则称为顺流。
