  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. 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

    對鍋爐本體進行了燃料燃燒計算、爐膛結構熱力計算、對流受熱面結構熱力計算、鍋爐給水加熱器結構參數設計、煙道阻力計算及鍋爐元件強度校核等；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，更充分的利用爐膛出口煙氣余熱，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。
  3. And it is calculated and analyzed the distribution and quantity of slag thermal stress created by boiler load shift. thermal stress quantity can be as big as e / 1000 and is enough to destroy slag structure and to make some drop. it is also concluded that the walltube parameters can only affect on thermal stress of the slag that is near to contact surface and contribute little to slag drop

    針對鍋爐變負荷運行時爐膛的自然掉渣現象，分析鍋爐水冷壁渣層中熱應力的產生機理，建立了水冷壁渣層熱應力的計算模型，計算分析了鍋爐大范圍變負荷運行產生的渣層熱應力變化大小和分佈，並分析渣層熱應力的影響因素。
  4. 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。
  5. And the conclusion is that downing load can distory the small slag and outer part of thick slag, which is helpful to keep walltube clean and useless for preventing from furnace accident caused by slag

    鍋爐降負荷運行有一定程度清潔爐膛水冷壁作用，能增強爐內傳熱，卻無法防止爐膛內結渣惡化發生嚴重事故。
