Abstract
Abstract A device for degassing water under excess pressure comprising a vessel with at least one nozzle spraying, in operation, water in the form of a screen projecting above the water level in the vessel, wherein in the path of the water screen the nozzle is surrounded by surfaces breaking up the jets and forming part of a splash grating formed by a plurality of strips arranged on end and overlapping each other in a direction of height and being relatively off-set in the direction of flow of the water from the nozzle, a higher strip being located, viewed in the direction of outflow, behind a lower strip.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
149 words
A DEVICE FOR DEGASSING WATER SUCH AS BOILER FEED WATER COMPRISING IN COMBINATION: A CLOSED VESSEL HAVING STEAM SUPPLY MEANS FOR SUPPLYING PRESSURIZED STEAM AND INCLUDING A STEAM INLET CONDUIT EXTENDING INTO SAID VESSEL AND A STEAM DISTRIBUTION MANIFOLD PRESENTING STEAM DISCHARGE OPENINGS ADJACENT THE BOTTOM OF THE VESSEL TO DISCHARGE STEAM WELL BELOW THE SURFACE OF A BODY OF WATER CONTAINED IN THE VESSEL WHEREBY THE BODY OF WATER REMAINS IN RELATIVELY QUIESCENT STATE, SAID VESSEL HAVING VENT MEANS IN THE TOP REGION THEREOF FOR VENTING GASSES WHILE MAINTAINING THE INTERIOR OF SAID VESSEL UNDER SUPERATMOSPHERIC PRESSURE, SAID VESSEL HAVING A WATER DISCHARGE CONDUIT FOR MAINTAINING SAID SURFACE OF THE BODY OF WATER WITHIN THE UPPER REGION OF SAID VESSEL; SUPPLY MEANS FOR DELIVERING WATER UNDER PRESSURE INTO SAID VESSEL AND INCLUDING A SPRAY NOZZLE LOCATED ABOVE SAID SURFACE AND DELIVERING AT LEAST ONE HIGH VELOCITY JET SPRAY

Claim 3
Dependent Claim
39 words
A device for degassing water as defined in claim 1 wherein said nozzle delivers a shallow conical pattern of jet spray curtains and said surfaces surround said nozzle to define an open central region within which said curtains issue.
Claim 4
Dependent Claim
28 words
A device as claimed in claim 2 including a plurality of nozzles and corresponding splash gratings, the splash gratings of adjacent nozzles being in contact with each other.
Claim 5
Dependent Claim
36 words
A device as claimed in claim 3, characterised in that centrally between two nozzles a supply stub having a steam or hot condensate pipe is provided and in that the splash gratings extend around said pipe.
Claim 6
Dependent Claim
20 words
A device for degassing water as defined in claim 1 wherein said surfaces are defined by strips facing said nozzle.
Claim 7
Dependent Claim
21 words
A device as claimed in claim 5, characterised in that at least the topmost strip but one has recesses or apertures.
Claim 8
Dependent Claim
66 words
A device as claimed in claim 1, characterised in that said surfaces form part of a splash grating formed by perforated plates inclined upwardly and being at an acute angle to the direction of outflow of the water, the dams between the perforations being formed by punched, bent-over portions so that they extend in a direction of height and transversely of the jets of the screen.
