style="text-indent:25px">維護(hù)爐墻的半干法噴補(bǔ)技術(shù)：半干法噴補(bǔ)技術(shù)是一種現(xiàn)代化的噴補(bǔ)技術(shù)，其噴補(bǔ)料含水只有12%，對(duì)爐墻的副作用小。該技術(shù)以其獨(dú)特的優(yōu)點(diǎn)，引起焦化行業(yè)的重視。許多焦化廠均引進(jìn)了半干法噴補(bǔ)設(shè)備，收到明顯的爐墻噴補(bǔ)效果。半干法噴補(bǔ)技術(shù)的原理是:干粉料和液態(tài)黏結(jié)劑在噴管內(nèi)各行其道，在噴出之前的摻混器內(nèi)混勻并從噴嘴噴出，水量在10%~12%之間任意調(diào)節(jié)，其主體設(shè)備為轉(zhuǎn)盤噴補(bǔ)機(jī)，噴補(bǔ)能力為450kg/h~900kg/h，噴補(bǔ)用水靠針式閥調(diào)節(jié)，粉料在摻混器中與水混合。半干法補(bǔ)爐技術(shù)具有較高的技術(shù)含量，設(shè)備少、體積小、易于移動(dòng)、操作簡(jiǎn)單，對(duì)介質(zhì)無過高要求、噴補(bǔ)速度快、附著率高，對(duì)于剝蝕面積1m2、深度達(dá)50mm 的墻面，只需20余分鐘即可噴補(bǔ)好。但是對(duì)搗固焦?fàn)t而言修補(bǔ)后的強(qiáng)度不佳，掛料時(shí)間仍不理想，并仍含有部分水分，對(duì)爐墻有一定程度損害。安徽哪家氧熔棒爐墻開孔比較好休風(fēng)可以使?fàn)t墻結(jié)厚減少。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">重型爐墻的耐火磚筑體，根據(jù)所要求的砌筑精度可為五類：特類砌體：磚縫厚度不大于0.5mm； I類砌體：磚縫厚度不大于lmm； Ⅱ類砌體：磚縫厚度不大于2mm； Ⅲ類砌體：磚縫厚度不大于3mm； Ⅳ類砌體：磚縫厚度大于3mm。各類砌體用的泥漿(耐火泥)為：特類、 I類和Ⅱ類砌體用稀泥漿； Ⅲ類砌體用半濃泥漿；Ⅳ類砌體用濃泥漿。工業(yè)鍋爐高溫區(qū)一般為I類或Ⅱ類砌體；省煤器和煙道等部分為Ⅲ類或Ⅳ類砌體。二、輕型爐墻的結(jié)構(gòu)和特點(diǎn) 輕型爐墻適用于中小容量的電站鍋爐以及快裝鍋爐、移動(dòng)鍋爐。它可分為磚砌式和混凝土板式兩種。磚砌式輕型爐墻由耐火磚層．絕熱層和金屬密封皮組成。絕熱材料采用硅藻土磚、石棉白云石板等輕質(zhì)材料。因而爐墻的重量可以通過托磚架由鍋爐鋼架或受熱面管子予以支承或懸吊。鑄鐵拉鉤的作用是防止?fàn)t墻向爐膛中凸出。混凝土板式輕型爐墻則用耐火混凝土板代替耐火磚，較之磚砌式輕型爐墻有制作簡(jiǎn)單、安裝快、造價(jià)低等優(yōu)點(diǎn)。三、管承式爐墻(敷管爐墻)的結(jié)構(gòu)特點(diǎn) 爐墻重量由鍋爐水冷壁承受，而不與鍋爐鋼架直接**。它是由數(shù)層敷在水冷壁管上的耐火材料和絕熱材料所組成。它主要用于大型鍋爐。</p><p
