The steam injector has three connections: one for supply of the medium to be heated, one for the supply of steam and one discharge opening. The steam injector contains a venturi cone with an annular access opening for the steam. The steam flows into the cone-shaped area through the annular opening in the venturi and forms a 'jacket' around the liquid. The steam immediately condenses in the venturi, preventing air bubbles and water hammer. The medium is intensively mixed and heated by the steam in the venturi.
The ratio of steam to heated medium can be regulated infinitely and at any time from 0 and 100%. The optimum flow rate of the medium is 0.8 to 3.0 m/sec. The flow rate is limited through installation of a pressure regulator.
The steam injector can also be used for cooling superheated steam. The steam flows through the venturi, and cold water is fed through the annular gap. The cold water supply is set via a
temperature-dependent regulator to achieve the desired
All steam injectors are made entirely of AISI316 Ti or AISI321 stainless steel. Also available in special materials such as Hastelloy, Monel, PTFE or with a special customer-specified coating on request.
One Steam injector for DN 65 water connection and DN 25 steam connection with loose flange connection, nominal pressure PN16, injector material 1.4541 stainless steel, connecting flange material C22.8 in accordance with DIN standard:
Type RLF 65/25, PN 16/16
Order number = D-RLF-6525-16-41-22
D = type of connections/flanges, in accordance with DIN or ASA
RLF = type of injector, RLF = version with loose, rotatable flanges
6525 = nominal flow = DN65 water and DN25 steam
16 = nominal pressure class for injector and connection flanges = PN16 or PN25, PN40
41 = injector material = 1.4541 or 1.4571 stainless steel
22 = connecting flange material = C 22.8 or 1.4571
