VERTICAL HEATER Russian patent published in 2009 - IPC F22D1/32 

FIELD: heating.

SUBSTANCE: invention concerns power industry and can be applied in heat exchange aggregates of regeneration systems, heat supply systems for water heating by steam condensation in heat exchange surface tubes. Vertical steam and water heater includes distributive water chamber with heated water inlet and outlet pipes, case with steam inlet and condensate outlet pipe and steam and air mix outlet pipe, pipeline with guiding partitions, surface-type air cooler. Part of all heat exchange surface tube length of first passage at heated water inlet is placed in a chamber with bottom positioned at the normal condensate level plane in the case; throttle holes for air and steam mix inlet to chamber are made in vertical side wall of chamber at steam inlet side to form pressure difference between steam bulk in the case and inside chamber. Pipe for air and steam mix outlet pipe and heating steam condensate outlet pipe are installed on chamber, with upper part of heating steam condensate outlet pipe attached to chamber bottom and lower part positioned above condensate level in the case.

EFFECT: enhanced heat efficiency, prolonged life time and improved reliability of heater.
