Abstract
A method in which an air mass flow supplied to a compressor in a power plant is divided in a flow divider into a small partial flow and into a larger partial flow. The smaller partial flow is supplied to an ejector via an air cooler and a booster. The larger partial flow is supplied to the suction line of said ejector. Both partial flows are combined in the ejector. The mass flow which is combined at the outlet of the ejector can be used as pressurized air in various components of a power plant.
Claims20
A method for increasing the pressure of a gas from a compressor with a booster, comprising:
- subdividing a mass stream of the gas into a relatively smaller part stream and into a relatively larger part stream;
- cooling the relatively smaller part stream;
- delivering the relatively smaller part stream to an ejector via the booster;
- and
- combining the relatively smaller part stream with the relatively larger part stream at the ejector, wherein the relatively larger part stream is supplied to a suction nipple of the ejector and wherein the combined mass stream of the gas is picked up at an outlet of the ejector.
A device for increasing pressure of a gas from a compressor with a booster, comprising:
- a stream divider, via which a mass stream of the gas is adapted to be subdivided into a relatively smaller part stream and a relatively larger part stream;
- an ejector, to which the relatively smaller part stream is adapted to be delivered by the booster;
- and
- a bypass line, via which the relatively larger part stream is adapted to be delivered to a suction nipple of the ejector, wherein the relatively smaller part stream is adapted to be delivered to the booster via an air cooler.
