Reslts of study show that the flue gas energy distribution in the flue duct to appear in peculiar unbalanced regularity , the units with capacity over 300mw and large - scale tangential firing boilers are basically in this way 研究結(jié)果表明:煙道煙氣能量分布呈現(xiàn)特有的不平衡規(guī)律,且容量超過300mw機(jī)組等級(jí)的大型切圓燃燒鍋爐基本都是如此。
Through measuring residual swhirling flow field in the flue duct of a real boiler , and analysing layout features of front and back platen supe - heaters in large - scale tangential firing boilers , the flue gas energy distribution regularity in horizontal flue duct of tangential firing boilers has been studied 摘要通過對(duì)實(shí)際鍋爐煙道煙氣殘余旋轉(zhuǎn)流場(chǎng)的測(cè)量及大型切圓燃燒鍋爐前、后屏過熱器的布置特點(diǎn)分析,研究了切圓燃燒鍋爐水平煙道煙氣能量的分布規(guī)律。
Based on practical engineering , the multi - tangential firing technology and the variance perimeter wind technology were introduced in this paper too . from the practical point of view , in this paper , we state the application of multi - tangential firing technology to setting the high temperature corrosion of the water wall tubes of boiler 本文對(duì)鍋爐水冷壁高溫腐蝕有關(guān)機(jī)理、影響因素以及預(yù)防措施作了詳盡的論述,并結(jié)合工程實(shí)際,詳細(xì)介紹多切圓燃燒技術(shù)以及變異周界風(fēng)技術(shù),從實(shí)踐角度介紹多切圓燃燒技術(shù)在解決鍋爐水冷壁高溫腐蝕中的應(yīng)用。
