PCT No. PCT/DE95/00147 Sec. 371 Date Jul. 3, 1996 Sec. 102(e) Date Jul. 3, 1996 PCT Filed Feb. 6, 1995 PCT Pub. No. WO95/22037 PCT Pub. Date Aug. 17, 1995The heat exchanger (100) encompasses an vertical housing (1), in which a bundle (50) of parallel pipes (30) is provided, which pipes extend between a lower pipe header (10) and an upper pipe header (20) and can be flowed through by a hot process gas that enters at the intake (4) and exits at the outlet (9). At the outer circumference of the pipes (30), the heat of the process gas is transferred to a fluid cooling medium, for example air, that enters the housing (1) at the intake (17) and exits it at the outlet (24). The highest pipe (30) temperatures occur in the region of the lower pipe header, which, for this reason, is configured as a double pipe header (10) that is cooled by boiling water (FIG. 1).
