    特性描述 熱力系統參考 技術參數表

    1、三回程結構:WNS××-××一Q(Y)系列全自動燃氣燃油蒸汽鍋爐,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500C。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激化空間,加之使用合理先進的汽水分離裝置,主蒸氣品質相當穩定

    2、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的爐膛內的燃燒。

    Three return journey structures The WNsXX-XX-Q(y) seriesfull-automatic oil(gas) fired steam boiler, the structure all adopt to annoythree return journeys, undee hearth, whole wet back. The fuel iscombusting under tidy pressure in a hearth, the hot smoke follows ahearth backward through oppressing, the smoke turn of type 180, andgo in the second to smoke tubes, rear row to go into the atmosphereafter changing the heat through convection. To use the design thoughtsof the three return journey symmetry structure, three return journeysteam biolers with bigger capacity. Biggest characteristics in this kind ofboiler: Ali press component and tubes are symmetry, whole wet backstype of the bioler structure, with biggest of inside the structure of thecanister and the partiality fire box. It is advantageous to improve on theenough radiation area to be subjected to the hot side. but the convecton is made up of fire tube the second reture journey and threereturn journey. Returning room of fire connect with the plank and a hearth conjunctions, the back plank adoption spheroid to seal the headand tube after returning room of fire plank. The returning smoke room of the second return joumey and the third return joutney turned thesmoke room to constitute the smoke box, here temperature of smoke is already lower than 500CS. Therefore, fire-proof of the smoke box adoptight form of the structure. The design of this kind of bioler mainly considers the boiler check, fix and stable principle. The imports of boilerwater supply has a equipment of mixing of water, first the water flushes the smoke tube, then touch with hearth, raising the water ternperature ofthe water by contacted. Avoiding the partial creation lead cold ebullition of phenomenon. The steam boiler attains the biggest vaporizationspace, add of usage reasonable forerunner of soda separate thedevice, the main steam quality is very stable

    2. A undee hearth of the form( the choices os customers' basis)Aundee hearth of a form of this series boiler, enhanced the moving ofsmoke, and then enlarged the rediation area, to transmit heat by thisarea, increased a undee furnace. hearth intencity, and effectively weakenthe internal force of a undee hearth to build up transmits heat theresult, and then promoted the fuels combustions in a chest of furnace
