Description

Device for separating water from steam at steam vessel outlet of steam generator

As this is a public information case, the full text was not included.

2 is a sectional view similar to that of FIG. 1 of a steam generator comprising a water-steam separator according to the present invention. 3 is a partially enlarged cross-sectional view of the steam assist of the steam generator shown in FIG. 2 including a water-steam separator according to the present invention.

Claims (10)

When the steam filled with water crosses these tubes arranged on a steam container arranged on an outer lid that resists the pressure of the steam generator where the steam of water occurs, before it flows out of the top of the steam generator, the water can be separated by centrifugal force. The deflector is arranged by giving a spiral passage to the steam and is constituted by a unit of a vertical cylindrical tube called a cyclone, which separates water from the steam at the outlet of the steam vessel of such a recycle steam generator, such as a steam generator used in nuclear power plants. In the device for the above, by means of improvement in which the cyclones are scattered in the subassembly, each cyclone of one subassembly is attached to the upper part of the supporting structure common to all the cyclones of the subassembly, and from the lower side to the upper side to the latter side. The upper part of the elongated steam container is formed vertically attached to the upper column through the inner part. The steam of the steam generator in communication with the cyclone of the corresponding subassembly forming the modulus of the cyclone attached to the top and the flared vessel and the separator on the one hand, in the form of a vessel flared into A device for separating water from steam at the vessel outlet. Separator according to claim 1, wherein the support of the support structure of the cyclone subassembly has a cross section smaller than the sum of the cross sections of the tube cyclones of the corresponding subassembly. Apparatus according to claim 2 in which the water supply of the steam generator is constituted by a toric pipe arranged between any supporting column of the cyclone separator. A device according to claim 1, wherein the flared vessel with a cyclone separator has a hexagonal cross section through the generator section and the separator-cyclone is arranged in a hexagonal mesh shape inside the cross section of the steam generator. Separation device according to claim 2, wherein a flared vessel with a cyclone separator has a hexagonal cross section through the cross section of the steam generator, and the separator cyclone is arranged in a hexagonal mesh shape inside the cross section of the steam generator. Separator according to claim 3, wherein the flared vessel with the cyclone separator has a hexagonal cross section through the cross section of the steam generator, and the separator-cyclone is arranged in a hexagonal mesh shape inside the cross section of the steam generator. Separator according to claim 1 wherein each subassembly comprises seven separator-cyclones. Separator according to claim 2 wherein each subassembly comprises seven separator cyclones. Separator according to claim 3 wherein each subassembly comprises seven separator cyclones. Separator according to claim 4 wherein each subassembly comprises seven separator-cyclones. ※ Note: The disclosure is based on the initial application.
