Abstract
A flow momentum enhancing device having an airfoil shape is used in a new or refurbished burner to increase the momentum of the burner combustion air stream and create a reduced pressure region which pulls inert products of combustion into the combustion process. The inert products of combustion mix with the burner air and/or fuel streams to lower the peak flame temperature of the burner and provide reduced NOx production.
