The present embodiment includes: an outer cell; an inner cell disposed inside the outer cell; a dilute solution supply pipe for supplying a dilute solution into the outer cell; a burner for generating combustion gas inside the inner cell; a plate-type heat exchanger disposed between the outer cell and the inner cell so as to exchange heat between the dilute solution and the combustion gas; and an exhaust duct for guiding the combustion gas having passed through the plate-type heat exchanger, wherein the plate-type heat exchanger includes a plurality of heat transfer units stacked in the direction orthogonal to the flow direction of the combustion gas, the heat transfer unit has an inner passage, through which the combustion gas passes, formed to be long in the horizontal direction between a pair of heat transfer bodies of which one end of each is connected and the other ends of each are joined, the heat transfer body has a joining body joined to the other adjacent heat transfer unit, and a dilute solution space for accommodating the inner dilute solution of the outer cell is opened in the vertical direction between the heat transfer units, which are adjacent to each other, among the plurality of heat transfer units, and the present invention has simpler manufacturing than when thin sheets are continuously folded and bent, and has high reliability. 본 실시예는 아우터 셀과; 아우터 셀 내부에 배치된 이너 셀과; 아우터 셀의 내부로 희용액을 공급하는 희용액 공급관과; 이너 셀 내부로 연소가스를 발생하는 버너와; 아우터 셀과 이너 셀 사이에 배치되어 희용액과 연소가스를 열교환하는 판형 열교환기와; 판형 열교환기를 통과한 연소가스를 안내하는 배기 덕트를 포함하고, 판형 열교환기는 연소가스의 유동방향과 직교한 방향으로 적층된 다수의 단위 전열유닛을 포함하고, 단위 전열유닛은 일단이 연결되고 타단이 접합된 한 쌍의 전열 바디 사이에 연소가스가 통과하는 이너통로가 수평 방향으로 길게 형성되며, 전열 바디에는 인접한 타 단위 전열유닛과 접합되는 접합 바디가 형성되고, 다수의 단위 전열유닛 중 서로 인접한 단위 전열유닛의 사이에는 아우터 셀 내부의 희용액이 수용되는 희용액공간이 수직방향으로 개방되어, 얇은 판을 연속적으로 접어 구부리는 경우 보다 제조가 용이하고, 신뢰성이 높은 이점이 있다.
