在選擇傳熱元件時，要考慮到用戶的實際情況，從設備長期安全穩(wěn)定運行的角度出發(fā)，適應煤種在一定范圍內的變化，確保在使用過程中不堵灰，保持較低的排煙溫度，保證在長時間的運行過程中，鍋爐的效率保持在較高水平。而不能*考慮單一設計煤種，在燃料變化后，無法滿足機組經(jīng)濟、穩(wěn)定和安全運行的需要。元件板型的選擇需同時考慮傳熱效果、流通阻力和堵灰可能三個因素。采用傳熱效果好的傳熱元件能降**造成本，但是不一定流通阻力小或耐堵灰，造成運行成本上升。例如某公司在預熱器冷段采用HS7、HS8等DU系列波形元件，雖然預熱器轉子重量變輕，但是當燃料灰分變多，或用于SCR預熱器時，很容易造成堵灰，使阻力上升。傳熱效果和流通阻力往往構成一對矛盾，因為提高換熱效果是通過加強氣流通道的局部紊流狀況，即加大換熱表面波紋密度或傾斜角，但這種方式也同時加大了流通阻力系數(shù)。山西空氣預熱器哪家便宜空氣預熱器的作用是使高溫煙氣冷卻，減少有害氣體排放。</p><div
