  1. This thesis establishes the main factor of heating surface slagging of no. 1 boiler, that it is due to irrational layout of furnace heating surface, improper angle of burner which lead to flames attaching to furnace walls. such deduction is built on the basis of necessity of analyzing the heating surface slagging, the type of coal, the design of the furnace and burner, the operational condition and other factors effecting slagging of boiler. the research is mingled with practical operations of no. 1 boiler in inner mongolia fengtai electric power generation co, ltd

    本論文從分析燃煤鍋結渣問題必要性出發,從煤種、及燃燒器設計、運行工況等因素對鍋結渣的影響著手,結合內蒙古豐泰發電有限公司~ # 1鍋實際運行中存在的問題,確定了~ # 1受熱而結渣的主要原因是受熱面布置不合理,燃燒器角度不合適導致火焰貼壁所致。
  2. This article aims at the boiler ' s problems in operation : 1 ) under nominal load, the smoke temperature at the outlet of hearth reaches 1200, far more exceeds 1050 the original designed temperature. this will always result in slag inside boiler and the temperature of overheater ' s pipe superheat, so that boiler cannot take nominal load and all these influence boiler ' s nomal operation heavily, 2 ) this article also studied the reason why the assistant oil becoming necessary when coal changes. during the nomal operation, many factors ( makeup of combustor and its disposal, smirch and encrust of water wall, excessive air coefficient, temperature of primary air, coal type and density of coal dust ) can deviate the designed working conditions, then affect the boiler ' s nomal operation

    本文針對該鍋在實際運行中存在的問題:在額定負荷下,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的設計工況,從而影響內的傳熱和燃燒,造成出口超溫、水冷壁結渣等問題。
  3. The question about burning method existing in spraying high pressure steaming in chamber is analyzed. the principle and character of auto supplying water, additive, steaming and combustion - support technology are introduced, also the economic benefit is analyzed

    分析了傳統內噴射高壓蒸汽燃燒方法存在的問題,介紹了鍋全自補水加劑注汽助燃技術的機理、特點。
  4. After thermodynamic calculation on several operation conditions of the furnace, cold - state flow and resistance mensuration, the combustion of the tubular - furnace hearth was changed into swirl and addition of radiate cylinder and oxygen content detection minish 1. 25 surplus air to less than 1. 15, improving the combustion condition and convection and radiate heat transfer efficacy, resuling in reducing the waste - gas temperature 45, decreasing exhaust gas loss, and saving fuel by 6 %

    摘要通過對加熱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溫度場分佈及管壁溫度等參數的測定,確定將管式加熱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 ,減少加熱排煙損失,節約了煤氣量6 %以上。
  5. 3. on boiler retrofit, the calculation of fuel burning, the heat calculation of boiler inside structure and convection section, and the design of structure parameter of feed water heat exchanger are made. the flue gas channels " resistance calculation and the boiler strength verifying are also carried out. replacement of water cooling wall improves heat exchanging and decreases loss of heat radiant

    對鍋本體進行了燃料燃燒計算、結構熱力計算、對流受熱面結構熱力計算、鍋給水加熱器結構參數設計、煙道阻力計算及鍋元件強度校核等;改進了水冷壁布置使換熱效果更好,減少輻射換熱損失;改進對流段結構,更充分的利用出口煙氣余熱,提高熱效率;並且進行了煙氣阻力計算、熱效率計算和能量平衡測試,對改進后的稠油燃料和改進前進行了對比,燃燒狀況和熱效率有明顯改善。
