求助:這段里面 焚燒爐的“水墻”結(jié)構(gòu) 怎么理解? 已有2人參與
|
|
原文:The newer municipal incinerators are usually the continuously burning type, and many have “waterwall” construnction in the combustion chamber in place of the older, more common refractory lining. The waterwall consists of joined vertical boiler tubes containing water. The tubes absorb the heat to provide hot water for steam, and they also control the furnace temperature. With waterwall units, costly refractory maintenance is eliminated, pollution control requirements are reduced (because of the reduction in quench water and gas volumes requiring treatment), and heat recovery is simpler. Unfortunately, judging by European experience, corrosion of waterwall units may be a serious problem. 參考翻譯:較新的城市焚燒爐通常是連續(xù)燃燒型,在燃燒室內(nèi)很多都帶有“水墻”式結(jié)構(gòu),取代了陳舊的普通耐火襯里。水墻由帶水的連接垂直鍋爐管組成。水管吸收熱量從而為蒸汽提供熱水,并且水管也控制了爐子的溫度。水墻單元的使用讓昂貴的耐火維護(hù)被消除,污染控制的要求被減少(因?yàn)樾枰幚淼捏E冷水和氣體體積的減少),且熱量回收更簡(jiǎn)單。不幸的是,根據(jù)歐洲人經(jīng)驗(yàn)的判斷,水墻單元的腐蝕可能是一個(gè)嚴(yán)峻的問題。 |

在爐內(nèi)壁的水管,有幾組,降低爐內(nèi)的溫度,并產(chǎn)蒸汽,管子的工況差,易損壞。 發(fā)自小木蟲Android客戶端 |
