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

FIELD: power engineering.

SUBSTANCE: steam and water heater comprises a vertical vessel with at least one drop channel for condensed steam. In the lower part of the drop channel there is a perforated header installed transversely to longitudinal sections of a tube bundle for collection and drain of non-condensed gases, as well as at least one header for collection and drain of non-condensed gases arranged longitudinally to transverse sections of a tube bundle. Headers for collection and drain of non-condensed gases are equipped with an umbrella arranged above and are made with suction holes.

EFFECT: design of a steam and water heater will result in even discharge of non-condensed gases from a zone of their maximum concentration in a lower part of a drop channel, which improves heat exchange in a tube bundle and reduces corrosion of internal elements of design.
