2、在爐體底部，從中心線向兩邊放砌筑輔助線到爐殼的距離。去除爐殼上的油污、銹漬，將纖維板貼靠在爐殼上，然后放線砌筑輕質(zhì)保溫磚；砌筑輕質(zhì)保溫磚時(shí)，上下兩層應(yīng)采用錯(cuò)縫砌筑，砌體表面要求平整，與纖維板接觸的位置要緊密壓實(shí)。輕質(zhì)保溫磚的砌筑，應(yīng)按設(shè)計(jì)要求預(yù)留膨脹縫，一般在10~20mm。 3、爐墻砌筑完成后，澆注料施工前，應(yīng)先標(biāo)記好叫澆注料施工的膨脹縫位置，然后在爐墻砌體上敷設(shè)一層防水薄膜，防止?jié)沧⒘鲜┕r(shí)，向耐火磚砌體中滲水。在膨脹縫處砌筑n1粘土耐火磚，防止?fàn)t內(nèi)熱量通過(guò)膨脹縫溢出。

style="text-indent:25px">鍋爐爐墻用耐火材料，主要用在鍋爐燃燒室的爐墻部分，爐墻部分是鍋爐的外部結(jié)構(gòu)，起重要的保溫和密封作用，爐墻能阻擋爐內(nèi)和煙道內(nèi)的煙氣外泄，爐墻的溫度是從下往上逐步高起來(lái)的，高度的不同其耐火層的厚度以及保溫層的厚度也是不同的。為了防止環(huán)境污染、降低熱損失，為了兼顧鍋爐生產(chǎn)過(guò)程中降耗和安全的需要，鍋爐爐墻用耐火材料應(yīng)具有的特點(diǎn)為有： 1、耐熱性。爐膛的水冷壁一般布置比較稀，有的部位甚至不布置，因此爐墻向火面的溫度通?？蛇_(dá)1000-1350℃，耐火保溫磚耐火澆注料在高溫火焰的輻射和高溫?zé)煔獾淖饔孟?，并受爐渣的化學(xué)侵蝕。 2、熱震穩(wěn)定性。在鍋爐爐膛溫度發(fā)生變化或鍋爐啟停中，爐內(nèi)會(huì)發(fā)生劇烈的溫度變化時(shí)，產(chǎn)生的交變溫度的內(nèi)應(yīng)力應(yīng)不引起爐墻的結(jié)構(gòu)性破壞，保證爐墻的完整性。 3、保溫、密封性。工業(yè)鍋爐一般為負(fù)壓運(yùn)行，爐墻的耐火磚澆注料如導(dǎo)致?tīng)t墻不嚴(yán)、冷空氣漏入，會(huì)破壞合理配風(fēng)，降低鍋爐效率減低鍋爐壓力，產(chǎn)生冒煙、漏灰、噴火等情況，影響鍋爐安全運(yùn)行。</p><p

爐墻直接砌筑在鍋爐地基上，即爐墻重量是由鍋爐墻基直接承受。爐墻一般由耐火磚與紅磚兩層組成。爐墻較厚，一般為500mm厚，質(zhì)量也較重。重型爐墻由于直接砌筑在鍋爐基礎(chǔ)上，且因重量較大，因此，高度受到限制。過(guò)高時(shí)，一方面使?fàn)t墻不穩(wěn)定，另一方面也由于在高溫下強(qiáng)度有限，故一般不超過(guò)10m，超過(guò)10m以上必須采取結(jié)構(gòu)措施，如可采用簡(jiǎn)單的金屬框架來(lái)加強(qiáng)其穩(wěn)定性。因工業(yè)鍋爐一般低于10~12m，故都采用重型爐墻。重型爐墻外層用標(biāo)準(zhǔn)紅磚240mm×115mm× 53mm砌筑，內(nèi)層用標(biāo)準(zhǔn)耐火磚T—3砌筑，其尺寸為230mm×113mm×65mm。耐火磚與紅磚之間留有20~30mm之間的縫隙，并填充絕熱石棉板或石棉粉。為了不使耐火磚與紅磚分開(kāi)，沿高度方向每增高5~7層耐火磚，要求從耐火磚向紅磚層內(nèi)插入半磚，使紅磚嚙合。為了保證爐墻自由膨脹，在四角和較寬的爐墻中間位置，沿整個(gè)爐墻高度留有垂直的溫度膨脹縫；在與鋼架、鍋筒、過(guò)墻管接觸部分也應(yīng)留出膨脹空隙。一般膨脹縫的寬度為10～25mm，每隔5m爐墻寬度布設(shè)一道。膨脹縫中間嵌入石棉繩，以防爐渣進(jìn)入和漏風(fēng)，膨脹縫只在爐墻內(nèi)側(cè)(耐火磚層)布置。上海胸墻爐墻開(kāi)孔多少錢(qián)</p><p
