style="text-indent:25px">陶瓷換熱器傳熱效率高，節(jié)能效果明顯，用以預(yù)熱助燃空氣或加熱某些過程的工藝氣體，可節(jié)約一次能源，燃料節(jié)約率可達(dá)30%－55%，并可強(qiáng)化工藝過程，明顯提高生產(chǎn)能力。陶瓷換熱器的生產(chǎn)工藝與窯具的生產(chǎn)工藝基本相同，導(dǎo)熱性與抗氧化性能是材料的主要應(yīng)用性能。它的原理是把陶瓷換熱器放置在煙道出口較近，溫度較高的地方，不需要摻冷風(fēng)及高溫保護(hù)，當(dāng)窯爐溫度1250-1450℃時(shí)，煙道出口的溫度應(yīng)是1000-1300℃，陶瓷換熱器回收余熱可達(dá)到450-750℃，將回收到的的熱空氣送進(jìn)窯爐與燃?xì)庑纬苫旌蠚膺M(jìn)行燃燒，這樣直接降低生產(chǎn)成本，增加經(jīng)濟(jì)效益。當(dāng)換熱器夾套中通入冷卻水或無相變的加熱劑時(shí)，亦可在夾套中設(shè)置螺旋隔板或其它增加湍動(dòng)的措施。高效換熱器供應(yīng)企業(yè)</p><p

style="text-indent:25px">換熱器是將熱流體的部分熱量傳遞給冷流體的設(shè)備，又稱熱交換器。換熱器是化工、石油、動(dòng)力、食品及其它許多工業(yè)部門的通用設(shè)備，在生產(chǎn)中占有重要地位。換熱器在形式上可分為臥式換熱器與立式換熱器兩種，它們的區(qū)別主要有：立式換熱器：穩(wěn)定安全，需要垂直鋪設(shè)，通常采用塔狀結(jié)構(gòu)；占地少，安裝空間凈高要求高，一般≮3.5m，要求塔裙高度較高，操作需要平臺(tái)，拆卸清洗比較麻煩；結(jié)構(gòu)緊湊，配管容易；冷熱兩種流體一般逆流；傳熱系數(shù)較大，加熱滯留時(shí)間短，換熱效果較好。換熱器的結(jié)構(gòu)</p></p><br
