A gas diffusion system (1) for feeding a gas stream, in particular a passivating gas stream, into an apparatus (2), in particular a decomposer, of a urea plant; the system (1) extends along an axis (A) and has a gas feed conduit (20) having an outlet (23) from which the gas flows substantially parallel to the axis (A), and a diffuser assembly (21) for diffusing the gas supply from the conduit (20); the diffuser assembly (21) is shaped so as to intercept the gas stream flowing axially from the outlet (23), and divert it substantially radially with respect to the axis (A) and uniformly about the axis (A). |
