| 摘 要： | 应用能量平衡和(火用)分析方法,对小龙潭火力发电厂300MW机组热力系统能量转换过程进行了定量计算,分析了各个单元的能量有效利用及损失情况,指出了损失的主要部位和原因.结果表明:热量损失主要发生在凝汽器单元,凝汽器散失到周围环境中的热量为411.28 MW,占输入热量的51.57%,锅炉单元散失的热量为52.96 MW,占输入热量的6.64%,汽轮机单元散失的热量为20.40 MW,占输入热量的2.56%;(火用)损主要发生在锅炉单元,锅炉、汽轮机和凝汽器单元的(火用)损分别占输入(火用)的67.78%、18.54%和13%;锅炉中燃料燃烧及大温差传热是整个系统不可逆的主要原因;不同工况下每个单元的(火用)损和(火用)效率会随着环境温度适度改变,但同一工况下机组总的(火用)效率不随环境温度变化. |
