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

FIELD: power industry.

SUBSTANCE: heat exchange method of gaseous media 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 disperse intermediate 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. Flow of intermediate disperse heat carrier at the outlet of the gas chamber is divided into two flows, each of which is then turned to opposite sides through 180° and directed along the walls of the gas chamber; after the gas flow passes through the intermediate disperse heat carrier, it is directed additionally along external perimetre of the air chamber.

EFFECT: improving operating efficiency of a heat exchanger by reducing heat losses during the working process.
