JUMBO BURNER Russian patent published in 2009 - IPC F23D14/20 

FIELD: heating.

SUBSTANCE: jumbo burner contains casing with co-axial installed pipe and channel for condensation drainage. At the section of pipe, installed in casing, there are implemented openings, in inlet part of pipe it is installed separator, implemented, for instance in the form of screw. Section of pipe, derived over the limits of casing is implemented in the form of convergent-divergent channel. Cavity of channel, from one side, is opened into annular gap between casing and pipe, from the other - is connected to cavity of convergent-divergent channel, and channel is implemented in the form of tube, installed outside the casing, herewith one end of tube is installed in casing, and from the other - is located in area of butt of profiled convergent-divergent channel. Channel can be implemented in the form of several tubes, installed outside the casing, with even angular pitch, and ends of tubes can be installed by helical curve, herewith direction of helical curve of ends of tubes inversely to direction of helical curve of screw.

EFFECT: more full separation of condensate from condensate-bearing gas, maximum possible combustion efficiency of gas with reduced content of injurous additives in combustion materials.
