Abstract

1. Apparatus for heat exchange between a recycle gas leaving an NH3 -converter and water, comprising heat exchanger tubes (11a, 11b) through which the recycle gas flows and which are gas-tightly connected to at least one tube plate (6) separating a pressure-resistant pre-chamber (5) and a heat exchanger chamber (3), wherein the pre-chamber (5) has at least one bell (10) for supplying the recycle gas and a collecting chamber surrounding the bell (10) for carrying away the cooled recycle gas, characterised in that the tube plate (6) is additionally provided with cooling bores (12) through which flows a water/steam mixture and which do not completely pass through the tube plate (6) from the heat exchanger side and which are communicated in their base regions by way of feed bores (13) with a water supply (14) through which the supplied water is fed into the heat exchanger chamber (3) by way of the cooling bores (12), and that the supply conduit to the externally cooled bell (10) is arranged in the associated outlet connection (7) of the pre-chamber (5) and the remaining annular space (9) in the outlet connection (7) has cooled recycle gas flowing therethrough.
