1、第V頁(yè)58MW強(qiáng)制循環(huán)熱水鏈條鍋爐設(shè)計(jì)摘要我國(guó)城市集中供熱事業(yè)得到了快速發(fā)展。大容量熱水鍋爐是城市集中供熱的熱源，選擇大容量熱水鍋爐的原則應(yīng)當(dāng)是不僅保證在鍋爐水質(zhì)達(dá)標(biāo)的情況下能夠保證水動(dòng)力的安全，而且對(duì)于水質(zhì)稍差時(shí)也能保證鍋爐的安全運(yùn)行。大型鏈條爐排熱水鍋爐的爐型主要有單(雙)鍋筒水管式熱水鍋爐、水火管鍋殼式熱水鍋爐和角管式熱水鍋爐三大系列，盡管這些爐型在運(yùn)行中也都程度不同地出現(xiàn)過(guò)各種問(wèn)題，但目前仍然是我國(guó)集中供熱鍋爐的主要爐型。本鍋爐為強(qiáng)制循環(huán)熱水鍋爐，用于集中供熱，熱水經(jīng)過(guò)中間換熱站換熱后向用戶供暖。文章概括敘述了本鍋爐的設(shè)計(jì)情況，包括鍋爐的熱平衡，鍋爐
2、本體的熱力計(jì)算、煙道阻力計(jì)算等,并以鏈條爐的大型化發(fā)展作為專題研究。隨著集中供熱事業(yè)的發(fā)展，更多的大型鏈條爐排熱水鍋爐將被用于集中供熱系統(tǒng)的主熱源或調(diào)峰熱源，如何選擇大型鏈條爐排熱水鍋爐的結(jié)構(gòu)形式和對(duì)鍋爐容量進(jìn)行合理配置，對(duì)于供熱企業(yè)的節(jié)能安全運(yùn)行及節(jié)能降耗具有著重要的現(xiàn)實(shí)意義。關(guān)鍵詞:鏈條鍋爐；集中供熱；大型熱水鍋爐第V頁(yè)58MWforcedcirculationhotwaterchainboilerdesignAbstractChina'surbancentralheatinghasbeentherapiddevelopmentofthecause.La
