ABSTRACT:
A burner for use in a heat regeneration system for a combustion furnace. The burner includes a burner shell having two internal chambers, wherein the first chamber is disposed on the flame axis of the burner, and the second chamber surrounds the radial perimeter of the first chamber. A gas permeable, annular regenerative bed separates the first and second chambers such that gas flow between the first and second chambers must travel through the regenerative bed in a direction which is generally radial with respect to the flame axis. The burner has "flue" and "fire" modes of operation. Valving elements are included for supplying combustion air to the second chamber under pressure when the burner is in the fire mode, and for exhausting products of combustion (POC) from the second chamber when the burner is in the flue mode. In the disclosed embodiment, the burner valving elements are annular and integral with the burner body. A fuel tube with a novel nozzle supplies fuel around the flame axis for mixing with the combustion air to support combustion when the burner is in the fire mode. An integral annular eductor is included for sucking the POC out of the second chamber when the burner is operating in the flue mode, whereby pressure within the furnace or radiant tube is maintained slightly positive or negative.
