Abstract
A system for transferring heat to an impingement surface includes a first radial jet reattachment combustion nozzle operable to direct a flame toward the impingement surface and comprising a central longitudinal axis. The system also includes a second radial jet reattachment combustion nozzle operable to direct a flame toward the impingement surface and comprising a central longitudinal axis. The first and second nozzles are positioned such that the central longitudinal axes are substantially parallel and spaced apart such that flames directed from the first and second radial jet reattachment combustion nozzles interact with each other.

A system for transferring heat to an impingement surface, comprising:
- a first radial jet reattachment combustion nozzle operable to direct a flame toward the impingement surface and comprising a central longitudinal axis and an air supply pipe having a first inside radius;
- a second radial jet reattachment combustion nozzle and also comprising a central longitudinal axis and an air supply pipe having a second inside radius substantially equal to the first radius;
- and
- the first and second nozzles positioned such that the central longitudinal axes are substantially parallel and spaced apart such that the ratio of the distance between the central longitudinal axes to the first inside radius of the air supply pipe is in the range of about 6 to about 9.
