摘要：為了達到對工業鏈條爐經濟運行節能進一步優化的目的，對漏風單獨進行試驗并加以分析統計。采用一臺DHL14-1.25/130/70型鏈條爐在70%額定負荷下運行時，人為設置了爐膛、煙道漏風點的方法，結合能效測試設備進行鍋爐漏風對爐膛溫度、過量空氣系數、排煙熱損失、化學不完全燃燒損失的影響進行檢測，分析鍋爐漏風對鍋爐熱效率的影響。模擬多個漏風位置進行試驗分析，找到對鍋爐影響最為嚴重的漏風部位，并提出改進措施，從而達到工業鏈條爐的經濟運行。

Abstract：In order to achieve the purpose of further optimization of the industrial chain boiler economic operation energy saving, the air leakage test was tested and analyzed statistically. In view of a DHL14-1.25/130/70 type chain grate in 70% of the rated load operation,we artificially set a hearth, a flue air leakage points. Combining with test of equipment for energy efficiency of boiler air leakage on the furnace temperature, excess air coefficient and heat loss due to exhaust gas and chemical incomplete combustion loss effect detection,and by which the influence of air leakage of boiler on boiler thermal efficiency is analyzed. Simulated multiple air leakage locations are tested and analyzed. The most serious air leakage location influences on the boiler are found, and improvement measures are proposed to achieve the economic operation of the industrial chain boiler.

近年來，鏈條爐的優化燃燒越來越引起人們的關注[1-4],但鏈條爐以及其他爐型的漏風問題很容易被忽視。由鍋爐漏風引起的鏈條爐熱效率降低，不被鍋爐使用單位、鍋爐安裝單位重視[5]。鍋爐漏風可分為爐膛、風道、煙道漏風，鏈條爐風道漏風后的冷空氣可以參加爐膛的燃燒，對鏈條爐的燃燒效果、各項熱損失的影響相對較少。由于鏈條爐的爐膛、煙道一般處于負壓狀態，冷空氣可以通過……
