1. An ammonia plant, comprising:

a first reactor configured to generate a first ammonia synthesis;

a second reactor configured to generate a second ammonia synthesis;

a start-up oven having at least one first heat exchanger; and

a piping system interconnecting the start-up oven to the first and second reactor;

wherein said start-up oven is connected to the first reactor via first pipes of the piping system for delivering reactants for a first ammonia synthesis and connected to the second reactor via second pipes of the piping system for delivering reactants for a second ammonia synthesis;

wherein the start-up oven is arranged in the flow path of the piping system such that the start-up oven is selectably connectable only to the first pipes or only to the second pipes.
