Burner assembly for delivery of specified heat flux profiles in two dimensions
A burner is provided which includes a plurality of burner subunits that each share a single air supply, a single fuel supply and a single control system. Each burner subunit has a plurality of air orifices and a plurality of fuel orifices of sufficient quantity and of a cross-sectional area to control a transverse heat flux profile of the burner. The burner subunits are spaced with respect to one another to control a longitudinal heat flux profile of the burner. The single air supply and said single fuel are adapted to provide an air-fuel mix that ensures the transverse and the longitudinal heat flux profiles are maintained at different fuel and air input rates. A burner of similar design using premixed air and fuel is also disclosed.
