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。The result of experimentation on coupling effect of water and fertilizers on spring corn in the three gorges reservoir area indicate that water stresslead the effect low of highness and lai, and the most effect is made in shooting stage ; it has a significant positive correlation between the yield of corn and biomass, and hasn ' t none significant positive correlation between the yield of corn and the weight of roots ; the coupling effect of water and n is significant, but the coupling effect of water and k is not significant, the maximum yield of corn condition fitting - water and medium n, corn absorbs n has a threshold value during the growth, and using superfluous n is able to prick up soil drought and crop drought ; water is the leading factor which effects the yield of corn, next is n and k
