爐墻的密封性對蒸汽鍋爐運行的經(jīng)濟(jì)性有很大的影響。由于爐墻密封不嚴(yán)造成的漏風(fēng)，不但會有效增加鍋爐的排煙熱損失，造成額外的引風(fēng)電耗，也可能影響爐內(nèi)正常的燃燒過程。如果不計增加的鍋爐引風(fēng)電耗，則漏入鍋爐煙道中的空氣量每增加10.%，鍋爐效率降低約0.4%~0.5%。對于正壓運行的鍋爐，更要求爐墻嚴(yán)格密封，以確保運行人員的安全工作及鍋爐房的環(huán)境衛(wèi)生。 </p> <p> 蒸汽鍋爐爐墻的密封性可通過漏風(fēng)系數(shù)△a來反映，處于不同流程處的漏風(fēng)系數(shù)△a的值時不同的。對于微正壓鍋爐的近代蒸汽鍋爐，△a=0是設(shè)計時必須做到的，蒸汽鍋爐爐墻的密封性通常通過蒸汽鍋爐良好的密封設(shè)計得以保證。 </p><p style="text-indent:25px">半干法噴補技術(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)盤噴補機，噴補能力為450kg/h~900kg/h，噴補用水靠針式閥調(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、操作簡單，對介質(zhì)無過高要求、噴補速度快、附著率高，對于剝蝕面積1m2、深度達(dá)50mm的墻面，只需20余分鐘即可噴補好。但是對搗固焦?fàn)t而言修補后的強度不佳，掛料時間仍不理想，并仍含有部分水分，對爐墻有一定程度損害。爐墻開孔改善操作環(huán)境，提高加熱質(zhì)量。</p><div
