Abstract
A two stage rapid mix burner provides apparatus and method which significantly reduce the burner size of a rapid mix burner, and/or the burner pressure drop, while maintaining the rapid mix feature and stability of the basic rapid mix design. The burner can also be easily altered to fit in non-circular geometries, such as a corner or tangential fired boiler. The invention uses a circular basic rapid mix burner located internally of a larger burner which can be non-circular. The inner burner provides the flow of hot gases which stabilizes the outer burner. In effect, the combustion gases produced in the inner burner replace the strong internal recirculation flow generated by the basic RMB as an ignition source for the outer burner flow.
