1. A combustion chamber module having an annular combustion chamber enclosing a combustion space, a feed device for fuel, an injector assembly positioned in an annular configuration on a combustion chamber head and comprising injectors for feeding in the fuel, and a control device for controlling the feed device, wherein:
the feed device is configured for feeding in a liquid fuel and a gaseous fuel, the injector assembly includes:
injectors of a first injector type configured for feeding in the liquid fuel, and
injectors of a second injector type configured for feeding in the gaseous fuel, and
wherein the control device is configured to control the feed device such that:
in a first operating mode, the injectors of the first injector type are supplied with the liquid fuel without simultaneous supply of the gaseous fuel to the injectors of the second injector type, and
in a second operating mode, the injectors of the second injector type are supplied with the gaseous fuel without simultaneous supply of the liquid fuel to the injectors of the first injector type.
