HEAT EXCHANGE METHOD OF GASEOUS MEDIA Russian patent published in 2013 - IPC F28C3/12 F23L15/02 F28D13/00 

FIELD: power industry.

SUBSTANCE: heat exchange method of gaseous media, for example for hot gas and air, is proposed, by means of a regenerative heat exchanger with fluidised bed, which includes gas and air chambers with grids for parallel passage of heat exchanging media and in-series movement of intermediate disperse heat carrier. Grids are installed in inclined direction; axes of holes in them are directed towards grid ascending side; filling pipes are perforated and located in cavities of the chambers. Hot gas flow is passed through an intermediate disperse heat carrier with further movement of the obtained heated fluidised bed of heat carrier from the gas chamber to the air chamber with further passing through the above air layer. The flow at the gas chamber outlet is divided into two flows, each of which is then turned to opposite sides through 180° and directed along walls of the gas chamber, and additionally directed along external perimeter of the air chamber. Surfaces of the grids are provided with longitudinal ribs; height of the rib is chosen approximately equal to thickness of fluidised bed of intermediate disperse heat carrier.

EFFECT: increasing heat exchanger operating efficiency.
