ROTATING REGENERATIVE AIR-HEATER Russian patent published in 2008 - IPC F23L15/02 

FIELD: energy.

SUBSTANCE: in a branched gas pipes of a regenerative rotating air-heater, consisting of housing with supply and outlet gas and air pipes, upper and lower sector plates and rotor, separated by partition walls into sectors with filler, at a distance (0.5-0.7)d_eq (equivalent diameter of the outlet gas pipe) from the lower sector plate, perpendicular to the outlet gas pipe, there is a choker in the form of a disc with a projection height of (0.10-0.17)d_eq. As a result, air cupping in the air heater is reduced by more than 5%.

EFFECT: increase in efficiency of the regenerative air-heater.
