    摘要通過對加熱爐幾種工況進行熱力計算、冷態試驗的流場分佈及阻力測定和熱態試驗的爐膛溫度場分佈及管壁溫度等參數的測定，確定將管式加熱爐爐膛內直流燃燒改為旋流場燃燒和增加輻射筒，增設煙氣含氧量分析，可以將燃燒的過剩空氣系數從1 . 35減小到1 . 15以下，極好地改善爐膛內的燃燒狀況和對流輻射傳熱效果，從而降低排煙溫度45 ，減少加熱爐排煙損失，節約了煤氣量6 %以上。
  2. It is found that the liquid kerosene of injection upstream cavity could finish the process of atomization and evaporation in short distance, and enter into cavity through convection. aft wall is the primarily area of flame holding in cavity, and the only area when near the lean blowout limit, flame in area of fore wall are spread from it. cavity shear layer in reaction flow angle greatly to the main flow direction, and couldn ’ t reattach to aft wall anymore, it appears great difference in characteristics of cavity flowfield between non - reaction and reaction state

    研究發現:凹腔上游噴注的液體燃料能夠迅速霧化、蒸發，並在較短距離內依靠對流輸運過程進入凹腔內部;凹腔後壁始終是凹腔火焰駐留的主要區域，在貧油極限時，也是唯一區域，並存在明顯的火焰由後壁向前壁的傳播過程;燃燒狀態下的凹腔剪切層以較大角度向下游主流發展，不再附著于凹腔後壁，與冷流中的凹腔流場特徵相差較大。
  3. The security that the boiler burns depends on the stability of flame mainly, in order to avoid the emergence of the explosive incident of the boiler, the coal powder must be burnt steadily in the stove, if it is unstable to burn, temperature field is not even in the stove, light to cause thermal efficiency of boiler reduce greatly, cause to waste, heavy and easy to is it produce stove serious consequence to present

    鍋爐燃燒的安全性主要取決於火焰的穩定性，為了避免鍋爐爆炸事件的發生，爐內煤粉必須穩定燃燒，如果燃燒不穩定，爐內溫度場不均勻，輕則導致鍋爐的熱效率極大地降低，造成浪費，重則容易出現爆爐等嚴重後果。
  4. The integral method is adopted caculate and analyze to amf three - dimension distruction which is the structure of coil type four - pole and the structure of coil type double - pole and study the size of two kind of electrode structure axial magnetic flux density distribution and its fielduniformity. the finite - element method is used simulate that eddy current has effect on amf when contact tray of douple - pole amf structure is slotted or no

    本文採用積分方法對本文設計的線圈式兩極縱向磁場觸頭結構和線圈式四級縱向磁場觸頭結構的縱向磁場三維分佈進行了計算分析。研究了電弧燃燒期間兩種觸頭結構縱向磁場強度的大小、均勻性，利用有限元法模擬線圈式兩極縱向磁場觸頭結構的觸頭盤開槽和不開槽時渦流對縱向磁場的影響。
  5. These results show that since the existent defects of combustion device structure and its hypothetical circle of contact, these make a poor primary and secondary wind rigidity in operation and a too big actual circle of contact. in addition, the coal used is extreme prone to burn and reside in boiler. under such a condition, the coal powder ignites earlier in a short time and short distance when it leave the jet - combustioning device, and splashes the water cooler, eventually this results in a burned coal residue in boiler

    針對宏偉熱電廠410t / h燃煤鍋爐嚴重結渣問題，對燃煤的結渣性、爐內溫度工況及空氣動力工況等進行實驗研究，由於燃燒器結構和假想切圓選擇的缺陷，使得鍋爐在正常運行時，一、二次風剛性較差，實際切圓過大，加上目前燃用煤質屬于極易燃、易結渣煤質，致使煤粉在離開噴燃器很短的時間、較短的距離內開始著火，並沖刷水冷壁，最終造成爐膛結渣。
  6. " the carbon dioxide from fossil fuels is distributed pretty evenly around the globe and not concentrated in the arctic, so it does n ' t look like we can blame greenhouse gases for the overwhelming bulk of the northern hemisphere warming over the past 27 years, " christy said

    然而，熱帶地區溫度在過去27年中僅僅升高了華氏0 . 3度。 「燃燒釋放的二氧化碳非常均勻地散布在全球，並非只集中在北極。所以過去27年間出現的北半球加速變暖的情況，好像並不能僅僅責怪溫室氣體。
  7. Applications of face - fired boilers are not so many on our country ' s industry, so the researches on it, especially on high - duty boilers ( for example 330mw ), are very limited. and further study is needed to make up for domestic vacancy about this. author of this paper has done some researches on 330mw boiler both in theory and experiments by applying computer aided test ( cat ) principles

    對沖燃燒鍋爐在我國的應用並不是很多，所以對它所進行的研究極為有限，特別是對于較大容量（如330mw ）的機組，相應的試驗和數值計算都很少，很多的問題仍等待進一步的研究，本文正是為了填補國內的空白，從理論和試驗的角度，運用計算機輔助優化數值試驗原理和方法，對330mw對沖鍋爐進行研究。
