Abstract

Heat exchanger has a horizontal transfer line (4) feeding hot process gas connected to the process gas generator (1). A connecting pipe (22) is arranged coaxially to each cooling pipe (11), so that on one side the connecting pipe (22) engages the cooling pipe (11) and leads out from the transfer line (4) on the other side. Heat exchanger for cooling a hot process gas produced in a gas generator (1) or a reactor comprises several cooling pipes (11) each surrounded by an outer tube (12). Each cooling pipe (11) and each outer tube (12) are welded at both ends to a water chamber (13, 14) for introducing and removing a cooling medium. The water chamber (13, 14) consists of a massive strip-like piece, into which circular recesses (15) are inserted corresponding to the number of cooling pipes (11). Each recess surrounds a cooling pipe (11) and has a diameter that is the same or is larger than inner diameter of the outer tube (12). The recess (15) has a thin annular base (16) having a low residual wall thickness. A horizontal transfer line (4) feeding hot process gas is connected to the process gas generator (1). A connecting pipe (22) is arranged coaxially to each cooling pipe (11), so that on one side the connecting pipe (22) engages the cooling pipe (11) and leads out from the transfer line (4) on the other side.
