STEAM GENERATOR GAS FLUE SCREEN STAND AND RESUPERHEATING CONTROL METHOD AT THEIR INCLUDING INTO IT CHANNEL Russian patent published in 2010 - IPC F22B35/14 

FIELD: heating.

SUBSTANCE: invention designed for overheating temperature control and can be used at heat power stations. Convectional shaft wall screens, connected by steam generator media to steam generator primary channel enter part or to resuperheating channel enter part via bypass with steam distribution device. Steam overheating temperature control method by steam consumption distributing between the overheating cannels convectional surface and its bypass in the steam generator overheating channel concludes in a way, that steam consumption distribution fulfilled either between convectional shaft walls screens and resuperfeated "cold" steam pipelines, in that case screens included in resuperheated channel until the resuperheated channel convectional surface, or between convectional shaft walls screens and resuperheated channel convectional surface, in that case screens included in resuperheated channel convectional surface bypass.

EFFECT: convectional shaft walls screens operation reliability increase in a start-up regimes, at significant heat radiation inequality and providing effective method of resuperheating temperature control.
