良好的煤粉配風是建立合理的爐內空氣動力工況和穩定燃燒的必要條件。而其中一次熱風送粉系統又是最重要的一個環節,一次風配風是否均勻直接關繫到煤粉在各燃燒器和各噴嘴中的分佈是否均勻,從而直接關繫到著火是否困難、火焰是否穩定、局部是否結焦以及鍋爐的熱效率高低。若一次風送粉系統發生堵塞和煤粉爆燃則可能引發嚴重的安全事故。The experience in building large - volume coke oven is summed up in terms of quality management of refractory, building of coke oven body, door, gas offtake pipe, fire bed as well as problems relevant to the building of coke oven body

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。Abstract : coke saving measures in the recent , years at pangang are summarized according to various ways of beneficiated materials , high blast temperature , oxygen - enriched blast , pulverized coal injection rate and improvement of blast furnace operation , the effect of related smelting factors on coke rate is investigated in combination with the production data and moreover further measures for reduction of coke rate are proposed
