一、三回程結構
WNS - -Q(Y)系列全自動燃油燃氣蒸汽鍋爐,均采用波形爐膽、煙氣三回程、全濕背結構。燃料在爐膽內微正壓燃燒,高溫煙氣沿爐膽向后經回燃室進入第一煙道管束,經壓迫式前煙箱轉折180 進入第二管束,經過對流換熱后排入大氣。利用中心對稱的三回程結構設計思想,設計容量較大的三回程蒸汽鍋爐。這種鍋爐最大的特點是:所有的受壓元件與鍋筒中心對稱,鍋爐采用全濕背式結構,以極大的內筒和偏心火箱的結構,其有利于提供足夠的輻射受熱面。而對流受熱面有第二回程和三回程的管束構成?;厝际仪肮馨迮c爐膽對接連接,回燃室后管板與筒體后管板采用后拉撐相連。第二回程和第三回程轉煙室構成了前煙箱,此處出煙煙溫已低于500℃。因此,前煙箱的結構采用輕形結構的耐火保溫材料。這種鍋爐的設計主要考慮了鍋爐的檢修和穩定性的原則。鍋爐給水進口處設置的混水裝置,給水線沖刷煙管管束,再接觸爐膽,提高了給水接觸爐膽的水溫。避免了局部產生過冷沸騰的現象。蒸汽鍋爐達到最大的汽化空間,加之使用合理先進的汽水分離裝置,主蒸汽品質相當穩定。
二、波形爐膽(根據用戶的選擇)
本系列鍋爐采用波形爐膽,既強化了煙氣的擾動,又增大了輻射傳熱面積;既增加了爐膽的剛度,又有效的減弱了爐膽的膨脹應力;既增強傳熱效果,又促進了燃料了燃料在爐膛內的燃燒。
三、煙管與火(煙)箱管板的焊接工藝
采用先預脹,消除管與管板之間的間隙,再焊接的工藝措施,有效的防止了高溫區可能腐蝕現象。煙管采用螺紋煙管。
四、對稱運動鉸接前、后煙箱門
前煙箱采用雙層結構保溫效果好。煙箱門采用鉸鏈結構,開啟方便,便于檢修,檢查,清理。
五、該型電蒸汽鍋爐專門為內蒙古鍋爐、鄂爾多斯鍋爐、包頭鍋爐、呼和浩特鍋爐設計,具有耐腐蝕、耐風沙的有點,配合以鍋爐水處理設備,可有效提高鍋爐在惡劣氣候環境下的使用壽命。
