STEAM AND WATER HEATER Russian patent published in 2013 - IPC F22D1/32 

FIELD: power engineering.

SUBSTANCE: bundles of tubular screens are installed in a body to form at least one receiving chamber. Each receiving chamber is arranged between appropriate adjacent bundles of tubular screens opposite to a nozzle of additional condensate supply fixed in the side wall of the body. In the receiving chamber there is a deflector shield installed, the medium section of which is installed opposite to the additional condensate supply nozzle, and edge vertical sections of the deflector shield are made as bent towards each other. Additional condensate is supplied into receiving chambers along nozzles from equipment, pressure in which is higher than in the considered steam and water heater. Downstream the supply nozzle the additional condensate, while expanding, arrives to the medium section of the deflector shield, where it partially suppresses its kinetic energy and is divided into two flows of more moderate head. By edge sections these flows are partially thrown to a flow of additional condensate leaving the nozzle and partially mixed in opposite jets.

EFFECT: mutual suppression of kinetic energy of flows takes place, which results in reduction of corrosion-erosion wear of this equipment.
