給水溫度提高對鍋爐熱效率有何影響?

??2022-08-05????????

給水溫度提高對鍋爐熱效率的影響可以分為兩種情況來討論。

第一種情況是假定鍋爐蒸發(fā)量不變。當給水溫度提高時，省煤器因傳熱溫差降低吸熱量減少，省煤器出口的煙溫提高，空氣預熱器的溫壓提高，傳熱量增加，熱空氣溫度略有提高。排煙溫度升高，使得鍋爐熱效率降低。但給水溫度提高后，用于蒸發(fā)的熱量增大，使蒸發(fā)量提高。為了維持蒸發(fā)量不變，必然要減少燃料量，這使得排煙溫度降低，鍋爐熱效率提高。由于這兩個因素對鍋爐效率的影響大體相當，因此，當保持鍋爐蒸發(fā)量不變時，給水溫度提高，鍋爐熱效率基本不變。

第二種是假定燃料量不變。當給水溫度提高后，省煤器的溫壓降低，省煤器出口煙氣溫度升高，預熱器吸熱量增加，排煙溫度升高，鍋爐熱效率降低。由于熱風溫度提高，爐膛溫度上升，水冷壁吸熱量增加。給水溫度提高后，用于提高水溫的熱量減少而用于蒸發(fā)的熱量增加，所以，給水溫度提高，如果燃料量不變則蒸發(fā)量增加，但鍋爐熱效率降低。
