A process for the catalytic oxidation of ammonia, comprising: passing an ammonia-containing gas, in the presence of oxygen, over a catalyst contained in a reactor, obtaining a process gas containing nitrogen oxides, and cooling said process gas with a heat exchanger accommodated in the reactor, wherein a portion of said process gas, located in the shell side, bypasses the heat exchanger and forms a hot current which mixes with cooled gas downstream the heat exchanger, and the bypass is regulated on the basis of a target outlet temperature of the mixed process gas.
