  1. 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。
  2. 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。
  3. Has analyzed the existing thermal power plant boiler superheat vapor temperature governign system control strategy, proposed exports the vapor temperature using the boiler the rate of change and the chamber exports the haze temperature to take the forward feed signal, the solution superheat vapor temperature adjustment hysteresis quality

    分析現有熱電廠鍋爐過熱蒸汽溫度調節系統的控制策略，提出利用鍋爐出口蒸汽溫度的變化率和爐膛出口煙氣溫度作為前饋信號，解決過熱蒸汽溫度調節的滯后性。
