Patent ID: 8475161

Claim:
A burner for heating spaces ( 3 ), in particular enclosed furnace spaces or interiors of jet pipes ( 1 ), comprising: a regenerator arrangement ( 10 ) including regenerators ( 11 - 16 ) for regenerative exhaust gas heat recovery and for heating combustion air utilizing exhaust gas heat, each of said regenerators comprising a regenerator channel ( 17 ) through which alternately an exhaust gas stream and a combustion air stream is established, a fuel supply channel ( 33 ) with a nozzle ( 9 ) for supplying fuel to the spaces ( 3 ), at least one combustion air nozzle ( 7 , 8 ) in communication with the regenerator arrangement ( 10 ) for conducting heated combustion air into the spaces ( 3 ) for oxidation therein of the fuel, and an exhaust gas exit channel ( 27 ) for conducting a partial exhaust gas stream—bypassing the regenerator channel ( 17 )—out of the space ( 3 ) to an exhaust gas discharge device ( 6 ), the regenerators ( 11 - 16 ) being arranged in the exhaust gas exit channel ( 27 ) so that the partial exhaust gas stream, while bypassing the regenerator channels ( 17 ), is in contact with the exterior surfaces of the regenerators ( 11 - 16 ).
