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。We select ni / cr alloy resistor as element together with ceramic embedding hearth ; select small flat - and - disc heat - even hubby ceramic sample holder, select ni / cr & ni / si thermoelectric couple ( type k ) as thermoscope with threads 0. 5 mm in diameter which is installed in the middle of the holders symmetrically ; select aluminum silicate fire - retardant fiber as materials for heat preservation ; design some hardware, for example temperature controller & transporter, signal amplifier etc ; design controlling curve to heat stove ; and introduce the method of least squares nonlinear regression and subsection function to deal with data. in order to obtain the reasonable operation conditions and operation curve, we have also done many theory analysis and experiment discussions

本論文通過冷、熱態試驗，經過論證和計算，確定了豐泰公司~ # 1爐燃燒器的改造方案，並進行了現場改造，改造后實際運行狀況表明：在無法改變爐膛結構的情況下，改變燃燒器角度，縮小切圓直徑，使火焰不貼壁，改善了爐內燃燒工況，同時降低了鍋爐結渣的程度，為機組的安全經濟運行奠定了必要的技術基礎。The mainly works had been done as follows : 1. in order to keep commonality, the modules who have similar thermodynamic process had been classed. such as evaporating module ( including furnace, drum, system of boiler recycled water ), single - phase heat exchange module ( including superheater, reheater, ecomomizer ), lubricating oil system module ( can be used for any lubricating oil system of rotation mechanical impedance ), pump and fan module, ect
本文所作的主要工作如下: 1 、為保證模塊的通用性，對鍋爐有相似熱力環節的模塊進行分類，建立模塊庫，便於模塊調用，如蒸發區模塊（包括爐膛、汽包和爐水循環系統） ，單相換熱模塊（包括過熱器，再熱器，省煤器等） ，潤滑油系統模塊（可用於各種轉機軸承潤滑油的動態特性的計算） ，泵與風機的動態計算模塊等。After appropriate reform measures were taken, the slagging and gas temperature deviation problemes have been completely solved. the boiler efficiency was raised by 2 percentage points and the boiler ' s safety and economics effect got improved
鍋爐經本次改造解決了爐膛出口煙溫偏高的問題，實現了鍋爐在130t h的額定工況下低溫段過熱器前煙溫由大修前的936下降到825的預期效果，並提高爐效2個百分點，使鍋爐運行的經濟性和安全可靠性得到改善和提高。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。We select crm without coal as reference ; select semi - dynamic atmosphere to operate machine ; use the method fixing the temperature of hearth and that of sample holders when the analysis begins, which ensures the consistency of heating samples ; adopt the dta curve of " at - t " to analyzing crm heat, which decreases possible influences from the fluctuation of heating velocity ; draw conclusions that crm proportion and granularity influence the analysis little, but not crm moisture and coal species ; advise that there be a warm - up to the crm with much moisture before analysis and a modification to the crm with variable species of coal ; then obtain the feasible operation conditions and operation curve ( together with the curve function )
