Abstract (en)
To provide a countercurrent direct-heating heat exchanger capable of suppressing wear of a container caused by a heating target fluid. A countercurrent direct-heating heat exchanger A includes: a container 10; a flow guide 40 connected to an inlet 12 for a heating target fluid 1 and guiding the heating target fluid 1 to flow in a vertically downward direction; and an umbrella-shape distribution plate 20 having a top arranged vertically below the flow guide 40. The flow guide 40 can suppress deflection of the heating target fluid 1. Thus, the heating target fluid 1 flows down to the top or the vicinity of the top of the umbrella-shape distribution plate 20 and is distributed uniformly in all directions of the umbrella-shape distribution plate 20. The amount of the heating target fluid 1 to contact the side wall of the container 10 is not increased locally to allow suppression of the wear of the container 10 caused by the heating target fluid 1.
