Abstract
A burner within which there is a jet pump means. High pressure primary combustion air is fed to an inlet in the burner housing and then through the jet pump means. The high pressure air flowing through the jet pump means draws a secondary low pressure, high temperature air into the burner. The jet pump means entrains the secondary air within the primary air to form a combustion air mixture. A fuel means feeds fuel to the burner housing and the combustion air and fuel combine to form a suitable mixture for ignition. A swirler can be located within the means to feed the primary air to the inlet or within the burner itself. By swirling the primary air the flame pattern of the burner can be controlled. The burner of the present invention is particularly adaptable for soaking pits having a tile recuperator and the metallic recuperator disposed within a flue gas passageway.
