一、三回程結(jié)構(gòu)
WNS - -Q(Y)系列全自動(dòng)燃油燃?xì)庹羝仩t,均采用波形爐膽、煙氣三回程、全濕背結(jié)構(gòu)。燃料在爐膽內(nèi)微正壓燃燒,高溫?zé)煔庋貭t膽向后經(jīng)回燃室進(jìn)入第一煙道管束,經(jīng)壓迫式前煙箱轉(zhuǎn)折180 進(jìn)入第二管束,經(jīng)過(guò)對(duì)流換熱后排入大氣。利用中心對(duì)稱的三回程結(jié)構(gòu)設(shè)計(jì)思想,設(shè)計(jì)容量較大的三回程蒸汽鍋爐。這種鍋爐最大的特點(diǎn)是:所有的受壓元件與鍋筒中心對(duì)稱,鍋爐采用全濕背式結(jié)構(gòu),以極大的內(nèi)筒和偏心火箱的結(jié)構(gòu),其有利于提供足夠的輻射受熱面。而對(duì)流受熱面有第二回程和三回程的管束構(gòu)成。回燃室前管板與爐膽對(duì)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(zhuǎn)煙室構(gòu)成了前煙箱,此處出煙煙溫已低于500℃。因此,前煙箱的結(jié)構(gòu)采用輕形結(jié)構(gòu)的耐火保溫材料。這種鍋爐的設(shè)計(jì)主要考慮了鍋爐的檢修和穩(wěn)定性的原則。鍋爐給水進(jìn)口處設(shè)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(chǎn)生過(guò)冷沸騰的現(xiàn)象。蒸汽鍋爐達(dá)到最大的汽化空間,加之使用合理先進(jìn)的汽水分離裝置,主蒸汽品質(zhì)相當(dāng)穩(wěn)定。
二、波形爐膽(根據(jù)用戶的選擇)
本系列鍋爐采用波形爐膽,既強(qiáng)化了煙氣的擾動(dòng),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(yīng)力;既增強(qiáng)傳熱效果,又促進(jìn)了燃料了燃料在爐膛內(nèi)的燃燒。
三、煙管與火(煙)箱管板的焊接工藝
采用先預(yù)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(qū)可能腐蝕現(xiàn)象。煙管采用螺紋煙管。
四、對(duì)稱運(yùn)動(dòng)鉸接前、后煙箱門(mén)
前煙箱采用雙層結(jié)構(gòu)保溫效果好。煙箱門(mén)采用鉸鏈結(jié)構(gòu),開(kāi)啟方便,便于檢修,檢查,清理。
五、該型電蒸汽鍋爐專門(mén)為內(nèi)蒙古鍋爐、鄂爾多斯鍋爐、包頭鍋爐、呼和浩特鍋爐設(shè)計(jì),具有耐腐蝕、耐風(fēng)沙的有點(diǎn),配合以鍋爐水處理設(shè)備,可有效提高鍋爐在惡劣氣候環(huán)境下的使用壽命。
