鍋爐配件之爐墻的作用和要求是什么？

??2022-08-03????????

爐墻的作用是將火焰及煙氣與外界隔離，減少散熱損失并使煙氣按一定的通道流動。

爐墻一般由三層組成。里面一層是耐火層，中間是絕熱層，外面是密封層。要求耐火層的耐火性能好，對灰渣的抗腐蝕性強，能長期承受高溫不損壞。耐火層常用耐火磚砌筑或澆灌耐火混凝土。對絕熱層的要求是絕熱性能好，一般用導熱性能低，比重小的材料，如保溫磚、石棉板、蛭石、珍珠巖、超細玻璃棉等。大多數(shù)爐墻的密封層用薄鋼板，常稱為護板。用薄鋼板作密封層，密封性能好，使用壽命長，又能增強爐墻的強度。也有用其他材料，如紅磚、聚醋酸乙烯粘貼玻璃絲布作密封層的。爐墻還要有一定的防震性，其結(jié)構(gòu)還要能使爐墻和鍋爐各部能自由膨脹并保持良好的密封，減少漏風。
