最新問答

為什么鍋爐引風(fēng)機及其前后的煙道要保溫？: 李工 | 技術(shù)工程工程師從鍋爐熱效率的角度看，引風(fēng)機及其前后煙道保溫，對提高鍋爐熱效率是沒有必要的。但是保溫后減少了空氣對煙道及引風(fēng)機的冷卻，提高其壁溫，對減輕低溫腐蝕是有利的。保溫還使煙氣溫度不因散熱而下降，煙氣溫度高，煙氣離開煙囪時......

為什么鍋爐送風(fēng)機入口風(fēng)道開口在爐頂上方較好？: 李工 | 技術(shù)工程工程師鍋爐的散熱損失，主要以對流和輻射的方式傳遞給周圍的空氣。在夏季高溫季節(jié)，室內(nèi)布置的鍋爐，鍋爐房內(nèi)的空氣溫度很高。鍋爐附近的空氣，由于溫度較高，密度較小而上升，周圍的冷空氣來補充，這樣鍋爐房內(nèi)的熱空氣大多聚集在上部。......

為什么有些鍋爐的送風(fēng)機入口風(fēng)道有可以切換的室內(nèi)和室外兩個入口？: 李工 | 技術(shù)工程工程師室內(nèi)布置的鍋爐，送風(fēng)機入口風(fēng)道開口在爐頂上方，可以回收部分鍋爐散熱損失。每臺鍋爐每小時需要的空氣量非常大，大約每噸蒸發(fā)量需要標(biāo)況下1000m3空氣。送風(fēng)機抽吸室內(nèi)的空氣，就要有相應(yīng)數(shù)量的外部溫度較低的空氣來補充，這對......

什么是鍋爐風(fēng)機的喘振？怎樣避免？: 李工 | 技術(shù)工程工程師對于Q-H特性曲線(流量與揚程特性曲線)呈駝峰狀的風(fēng)機來說，在運行中當(dāng)流量低于一定值時，有可能產(chǎn)生喘振(飛動)。風(fēng)機發(fā)生喘振時，產(chǎn)生劇烈振動，對設(shè)備安全運行危害很大。因此風(fēng)機是不允許在喘振狀態(tài)下運行的。下面分析風(fēng)機......

引、送風(fēng)機故障時，事故按鈕停止其運行時為什么手撳按鈕要保持一段時間？: 李工 | 技術(shù)工程工程師風(fēng)機運行中出現(xiàn)危及設(shè)備和入身安全的情況時，如機械故障，動靜部分摩擦，強烈振動，電機冒煙，有火花、弧光或入的手、辮子、衣服被轉(zhuǎn)動部分絞住時，應(yīng)立即按風(fēng)機附近的事故按鈕停止風(fēng)機運行。上述故障很突然，持續(xù)的時間很短，司爐在......

為什么鍋爐風(fēng)機啟動在15min內(nèi)不宜超過兩次？: 李工 | 技術(shù)工程工程師鍋爐風(fēng)機大多由異步電動機驅(qū)動，異步電動機的啟動力矩較小，啟動電流很大，約為正常運行時電流的6?7倍，大電流持續(xù)的時間視電動機容量大小約10~15s。電動機導(dǎo)線的發(fā)熱量與電流的平方成正比。電動機在啟動時將產(chǎn)生很多熱量，使......

為什么鍋爐引風(fēng)機的使用壽命比送風(fēng)機短？: 李工 | 技術(shù)工程工程師我國絕大部分大、中型鍋爐是采用+衡通風(fēng)的負壓鍋爐，由送風(fēng)機克服空氣預(yù)熱器和燃燒器的阻由引風(fēng)機克服煙氣流經(jīng)過熱器、再熱器、省煤器和空氣預(yù)熱#時形成的阻力。流過送風(fēng)機的介質(zhì)是含塵和有害氣體很、溫度為室溫的空氣......

裝有兩臺送風(fēng)機或引風(fēng)機的鍋爐，風(fēng)機反轉(zhuǎn)怎樣啟動？: 李工 | 技術(shù)工程工程師裝有兩臺送風(fēng)機或引風(fēng)機的鍋爐，由于導(dǎo)向葉片不嚴(yán)，常常會出現(xiàn)一臺風(fēng)機運行，而另一臺備用風(fēng)反轉(zhuǎn)的情況。由于異步電動機的啟動電流很大，而啟動力矩較+，風(fēng)機的慣性較大，風(fēng)機從啟動到正常所需的時間較長。當(dāng)風(fēng)機反轉(zhuǎn)時，由于葉輪......

大容量鍋爐為什么要設(shè)置兩臺引風(fēng)機或送風(fēng)機？: 曹工 | 技術(shù)工程工程師對于容量較大的鍋爐，為了安全和在低負荷時節(jié)約風(fēng)機耗電量，常設(shè)置兩臺引風(fēng)機和送風(fēng)機。當(dāng)鍋爐負荷較低時，一套風(fēng)機運行，另一套風(fēng)機備用，當(dāng)鍋爐負荷較高時，兩套風(fēng)機全部投入運行。由于備用風(fēng)機入口的導(dǎo)向葉片一般都不嚴(yán)密，風(fēng)機......

鍋爐運行中怎樣防止風(fēng)機風(fēng)機導(dǎo)葉脫落后掉入葉輪造成停爐？: 李工 | 技術(shù)工程工程師很多鍋爐的引、送風(fēng)機采用離心式風(fēng)機，其風(fēng)量調(diào)節(jié)大多采用改變?nèi)肟趯?dǎo)向葉片開度來實現(xiàn)。這種調(diào)節(jié)方式設(shè)備簡單，有一定的經(jīng)濟性。由于振動、磨損或腐蝕等原因，導(dǎo)向葉片兩端的軸有可能出現(xiàn)斷裂。因為送、引風(fēng)機入口的風(fēng)速高......
