Abstract
A system for the atomization of liquid is arranged on the intake duct of a gas turbo set. This atomization system comprises a number of nozzle tubes with atomizer nozzles, switching valves for selective action upon the nozzle tubes by liquid and a pump for conveying the liquid to be atomized. According to the invention, the pump is connected to a variable-speed drive. The switching valves are preferably designed as proportional valves. In a corresponding regulating circuit, this makes it possible to limit pressure gradients in the atomization system and consequently to avoid hammers.
Claims13
A method for injecting a liquid mist into an intake duct of an air-breathing thermal engine, comprising injection nozzles, pipelines, at least one pump and throttle and/or shutoff members which are arranged downstream of the pump for action upon nozzles and/or nozzle groups by liquid conveyed by the pump, the pump having a variable-speed drive, wherein variations in the pump rotational speed (n) are carried out with a predetermined amount of a rotational speed/time gradient.
