HEAT TRANSFER METHOD Russian patent published in 2010 - IPC F22B1/06 

FIELD: heating systems.

SUBSTANCE: heat transfer method, mainly in vertical once-through steam generator in the area of liquid-steam boundary line consists in the fact that there formed is evaporation section along path of heated liquid by supplying heat to heat exchange tubes throughout the length of the latter; heat is supplied to heated liquid close to saturation point when throttling it through double-channel throttle installed in path of each heat exchange tube thus creating static water level in steam generator. Heat exchange tubes are provided with reducers; at that, thickening is made in each tube between reducers, and to that thickening the above throttle is put.

EFFECT: increasing heat transfer from heating liquid to heated one.
