Abstract
In a two-stage ammonia converter containing at least one catalyst bed arranged in the pressure housing in annular fashion and a heat exchanger which can be flowed through by the reaction gas and is arranged centrally in the interior with respect to said bed, a solution is to be provided with which especially the guiding of the heat exchanger pipes, optimisation, decoupling of the length of the heat exchanger from the height of the catalyst bed and even a more favourable transmission of heat are achievable, where, in particular, a solution which is simple in construction terms should be found. This is achieved by constructing the heat exchanger (5) as a single-plate heat exchanger having heat exchanger tubes (6) arranged centrally in a plate (7) in a U-shaped manner, the side tubes of the U-tubes being arranged centrally for the inlet and being arranged on the circumference for the outlet. <IMAGE>
