Abstract
In a high efficiency regenerator burner for heating spaces, the exhaust gas generated by the burner is provided which is conducted alternately through different regenerator cartridges and a partial stream of the exhaust gas is conducted under the control of an orifice plate through a bypass space in which the regenerator cartridges are disposed. A control structure is disposed in a burner head for controlling the exhaust gas bypass flow volume and also to control the main exhaust gas flow as well as the combustion air flow through the regenerator cartridges.
Claims12
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).
