SUPERHEATER Russian patent published in 2010 - IPC F22G1/00 

FIELD: power industry.

SUBSTANCE: in housing cavity with uprising movement of superheated steam there arranged is a bank of evaporating tubes the inlet and outlet ends of which are connected to upper and lower vertical chambers respectively. There is specified condensate level in lower chamber in the area located below outlet ends of evaporating tubes. In housing cavity under the bank of evaporating tubes there arranged is a bank of evaporating cooling tubes the inlet and outlet ends of which are connected to lower chamber in the areas located above and below the specified condensate level respectively. Such superheater design allows using not only heating steam condensation heat, but also condensate heat of that steam for steam superheat.

EFFECT: heating steam flow through superheater decreases and steam flow through the turbine flow part increases, and economy of turbine plant is increased.
