　　一、設備出現(xiàn)積灰的原因<br /> 　　主要是由溫度低于灰的熔點然后導致積灰問題，日常我們可以分為高溫積灰與低溫積灰這兩種。高溫腐蝕會產(chǎn)生一些粘附性積灰與粘結(jié)性積灰，粘附性積灰主要是由于高溫煙氣中含有的低熔點金屬元素在煙溫降低時產(chǎn)生凝結(jié)物，然后形成一種封閉性灰環(huán)。結(jié)性積灰是在高溫區(qū)向過渡溫度區(qū)進行轉(zhuǎn)變的時候，因為煙氣對管子進行橫向沖刷，在管子正面形成熔融狀積灰導致煙管道被堵塞。當尾部低溫區(qū)面積大、燃燒的灰分進行增加，加上進風口的溫度偏低導致的燃燒不完全、鍋爐受熱面布置不平衡、吹灰設備不完善等原因?qū)е路e灰的形成。<br /> 　　二、鍋爐積灰的措施<br /> 　　1、使用翅片管，翅片管的設計可以有效的減少外形的尺寸以及水力和煙氣的阻力，然后通過加翅片管進而在尾片部位由于氣流繞流產(chǎn)生漩渦，然后讓顆粒的運行軌跡發(fā)生改變，使顆粒在繞過漩渦之后再沖擊導管壁上，顆粒的碰撞幾率減少且碰撞的位置發(fā)生后移，這樣能夠很好地起到防止積灰沉積的作用。<br /> 　　2、聲波吹灰機，聲波吹灰機可以利用震動作用在邊界層形成斷續(xù)，然后伴隨著煙氣的逆向流動這種不穩(wěn)定流動使得微粒難以沉積，并且破壞沉積物。<br /> 　　以上就是小編與大家分享的導致余熱鍋爐的積灰原因以及解決方法相關知識內(nèi)容了，我們?nèi)粘＿€需要定期的進行維護，避免后期影響使用。<br /></div> <div id="zwpc5lt" class="page"
