VERTICAL SHELL-AND-TUBE CONDENSER Russian patent published in 2011 - IPC F28B1/00 F28D7/00 

FIELD: power industry.

SUBSTANCE: to vertical shell-and-tube condenser containing cylindrical housing with lower and upper inlet and outlet branch pipes of heated heat carrier, bank of internal heat exchange tubes and external tubes installed coaxially so that inter-tube through annular channels are formed, as well as lower and upper grids for attachment of internal tubes and grid for attachment of upper ends of external tubes, at that, on the above cylindrical housing there is cover and bottom with branch pipes for supply of heat carrier to be cooled and discharge of cooled heat carrier, there additionally introduced is grid for attachment of lower ends of external tubes, which forms together with lower grid of internal tubes and cylindrical housing of condenser the distributing chamber of the heated heat carrier directed to inter-tube through annular channels. At that, some part of space between lower grid of internal tubes and bottom of condenser is interconnected by means of the tubes fixed in lower grids with volumetric space enclosed between external tubes, their grids and cylindrical housing that is equipped with discharge branch pipe of non-condensed gases. At that, discharge branch pipe of cooled heat carrier is equipped with floating valve.

EFFECT: stable and reliable operation.
