Definitions
- Both in heating and in process engineering gases or vapors must be cooled frequently.
- tense that is, is under a higher pressure as well as having a high temperature that is over 500 degrees Celsius can be.
- On the side of the heat consumer but often much lower temperatures are desired, so that it is necessary the steam temperature at the heat consumer belittling. This can be done, for example happen that the tense and superheated steam mixed with condensate, with colder steam or with cold water becomes.
- the superheated steam supply wet steam using a jet pump.
- the jet pump is with its blowing agent connection to the superheated steam connected and there is a too at their suction connection a conduit leading duct provided.
- the Jet pump sucks the steam in the steam trap Condensate resulting wet steam, whereby the wet steam in the jet pump with the superheated steam jet mixes.

- the steam cooling devices 10, 10a, 10c have in common that the steam velocity at the points of water injection very large and largely independent of primary steam flow rate. This results in a good control behavior from full load to light load. Furthermore is the steam quality of the cooled steam compared to known steam cooling devices emitted steam significantly improved. As a result of the intensive mixing of Steam and water within the mixing channel 62, 62a, 62b, 62c, the cooled steam is very homogeneous. It will possible to produce saturated or nearly saturated steam, that carries little or no water droplets.
