HEAT EXCHANGER Russian patent published in 2013 - IPC F22B1/06 

FIELD: power engineering.

SUBSTANCE: heat exchanger comprises vertical screens arranged longitudinally in a cylindrical vessel and made of pipes connected to a distributing chamber, a relief chamber and a collecting chamber of a central header. Pipes of vertical screens are made in plan as bent in direction from the header to the vessel. The heat exchanger also comprises vertical suspensions of screens arranged in the cross section of the vessel in a circular row, and an upper support ring arranged above screens in alignment with the central header and hingedly joined with the upper sections of the suspensions. Under the screens in alignment with the central header there is a lower support ring installed with guides for lower sections of suspensions. Each guide is fixed on the lower support ring with the possibility of vertical and radial displacement of the lower section of the appropriate suspension relative to the lower support ring.

EFFECT: reduced amplitude of pipe vibration, which reduces pipe wear and increases heat exchanger resource.
