In this paper, we study the effect of cooling dehumidification process and wave heat exchanger on the reduction of white smoke and the efficiency by combination of heat exchanger with numerical analysis method. For this purpose, four types of heat exchange systems combined with 5-stage wave heat exchangers were selected to analyze the heat transfer characteristics of the heat exchange system in the winter condition. As the high temperature exhaust air flowed from HX 1 to HX 5, the final outlet temperatures of the four heat exchange systems(Cases 1, 2, 3 and 4) gradually decreased. The heat transfer rate and dehumidification amount were the best in Case 1 and Case 3, respectively. It can be seen that the heat flow in the heat exchanger is different according to the combination of the four kinds of wave heat exchanger and the fluid flow.

Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF) 조성을 갖는 치밀한 관형 분리막은 압출 성형 방법으로 제조하였다. Ba0.5Sr0.5Co0.8Fe0.2O3-δ 관형 분리막의 구조적 특성은 x-선 회절분석기 (XRD)와 전자 주사 현미경 (SEM)을 이용하여 분석하였으며, 상대밀도는 94.10%를 보였다. 산소투과량 분석은 700~950℃ 범위에서 공급 측과 투과 측의 운전조건에 따라 측정되었다. 공급 측과 투과 측에서 대기 중 공기와 진공펌프를 사용할 경우, Ba0.5Sr0.5Co0.8Fe0.2O3-δ 관형 분리막의 산소투과량은 900℃에서 1.37 mL/min·㎠로 높게 나타났다.
