中文拼音 [zuìhòuyùrèqì]
最後預熱器
英文
final preheater-
Firstly, simulate flow field of rear smoke channel, plot velocity magnitude and ash concentration distribution in section of entry of heat pipe air preheater, compare with data which were measured in guiyang power station, verify simulation to be reasonable and right. secondly, simulate all kinds of factors which affect flow field ' s uniformity such as length, thickness, location of diffluent board, ash concentration, ash diameter, and so on, find the chiefly factors. thirdly, install guide board in curve channel in rear smoke channel, then simulate its " flow field, plot velocity magnitude and ash concentration distribution
在此基礎上模擬在冬夏兩季不同情況下，不同流速對熱管空氣預熱器壁面溫度的影響；然後對影響整個流場分佈的各種因素：包括分流板長度、厚度、偏離中心流道位置的偏離度、飛灰濃度、飛灰粒徑等因素進行數值模擬；最後提出在分流煙道轉彎處加裝導流板，並模擬加裝導流板后的流場分佈，得到下級空氣預熱器出口、熱管空氣預熱器進口處的斷面速度場分佈、濃度場分佈，以論證加裝導流板能達到流場均勻化的作用。In view of the characteristic of headers of dagang power plant, it has reserched and designed on the life prediction. cui ming ( power plant thermal power engineering ) directed by prof. han pu
最後以大港電廠過熱器和再熱器聯箱金屬診斷系統為研究對象，對其壽命預測方法進行了研究與設計。Taking some tubular air pre - heater used in one boiler whose capacity is 130 t / h as an example, new blue print with inner trachea is completed by means of computer program. several key design variables may be changed, such as diameter of pipe and velocity of flow of gas. these cases have been considered, and their results have also been compared with each other
比較了幾個重要的設計變量，如外管徑、煙氣流速等參數變化時，總傳熱系數和空預器本體管子總重量，阻力損失以及最低管壁溫度等幾個重要設計結果的變化趨勢，對內螺紋管空氣預熱器的設計具有借鑒意義；其間還分析了內螺紋管與光管在設計時的不同之處；最後，初步分析了內螺紋管的優化設計問題，提出了一些建議。In the end, the paper makes an thermodynamic analysis, evaluation of investment and techno - economic analysis on the retrofit plans of heat recovery steam generator and air pre - heater, which helps to make the evaluation of the plans from the view of energy conservation and economy benefit
完成熱管布置設計和設備細部結構設計，繪制余熱回收設計圖紙。最後對所設計的余熱鍋爐和空氣預熱器方案進行熱力學分析、投資概算和技術經濟分析，從節能和經濟性角度評價了設計方案的效益。分享友人
