Water injection device for a bypass steam system of a power plant

Abstract

A water injection device (1) for a bypass steam system of a power plant, comprising a flow channel (2) for steam with a steam inlet (8) and a steam outlet (10), and an injection nozzle (12) which is arranged between the steam inlet and outlet (8, 10), is to have a particularly satisfactory cooling action in order to avoid condenser damage by way of technically particularly simple means. To this end, the injection nozzle (12) is arranged on a wall (20) which extends substantially in the direction of the gas flow and is arranged spaced apart from an inner wall (6) of the flow channel (2).

Description

technical field [0001] The invention relates to a water spraying device for a bypass steam system of a power plant, said water spraying device comprising a flow channel for steam with a steam inlet and a steam outlet and a spray arranged between the steam inlet and the steam outlet nozzle. Background technique [0002] Power plants for the production of electrical energy typically use the thermal energy of the combustion process to produce mechanical energy, which is then converted into electrical energy in a generator. Usually, direct-fired steam generators are used here, which generate steam for the steam turbine. But the thermal energy used to generate steam can also be obtained from other sources, such as nuclear energy. Another way, not indirectly by generating steam, is to provide direct conversion, for example in a gas turbine. In this case, however, the hot exhaust gas of the gas turbine is usually additionally used in a waste heat boiler to generate steam. So in...
