The invention relates to a steam generator for humidifying an airplane air conditioning system. The steam is generated in a container (21). A support (50) enables a translational movement of a tubular part (49) connectable to a duct of a humidifier along the main axis of the container (21) in order to connect it with the outlet opening (24) of the container (21). Inside container (21), there are at least two electrodes (31, 32, 33) that are partially immersed in water and which are energized under a constant voltage up to a certain level of current in electrodes (31, 32, 33). Also, container (21) includes a fuse 38 with one end connected to a first of the terminals, the other end of the fuse being of the connected to one of the electrodes (31, 32, 33). A regulating unit (60) measures and maintains the intensity that current passing through electrodes (31, 32, 33). At the time of the installation of a new container, the regulating unit (60) determines whether the fuse (38) is or is not conductive. If the fuse is conductive, a current is sent through it to burn it out allowing the steam generator to be started. If not, the steam generator cannot be started until a new unused container having a conductive fuse is installed.
