本文針對該鍋爐在實際運行中存在的問題:在額定負荷下,爐膛出口超溫、低溫段過熱器前煙溫高達936 ,遠遠超過815的設計值;噴燃器四周水冷壁結焦嚴重,過熱器管壁溫度超標,無法帶上額定負荷;甚至有時因燃煤質量的變化,必須投油助燃的嚴重情況進行了分析研究。在實際生產過程中,燃燒器的結構、布置,水冷壁的粘污、結垢,過剩空氣系數、一次風溫、煤種及其濃度變化等許多因素都會偏離鍋爐的設計工況,從而影響爐內的傳熱和燃燒,造成爐膛出口超溫、水冷壁結渣等問題。According to finite element segmentation principle, by combining test with observation, the author has measured the air streamline and speed distribution of burning equipment in dally situation, which provides some guide for research of air field in hearth on cold and hot conditions. and the law is found of air speed distribution by measuring its speed and distribution of upper and lower deck on cold condition, thus it lays the foundation for analysis on hot condition. under four burning states, we measure the air speed in single, double - deck, and find out its corresponding distribution law
