The ZEECO® GB staged air/staged fuel burner is designed with a staged fuel gas tip and a staged air annulus, which utilizes only one gas tip and provides lower NOx emissions than conventional raw gas designs. With greater flame stability, the burner provides consistent heat distribution and reduces maintenance costs. This staged air method is designed to offer turndown of 10:1 or greater, which is a drastic improvement over other low NOx designs.
GB Staged Air Burner
Technology
The GB burner utilizes one tip to produce the primary combustion zone and the secondary combustion zone, which produces inert products of combustion that are induced into the staged fuel gas ejected straight up from the center of the gas tip. These products are then induced into the staged fuel gas ejected straight up from the center of the gas tip. Used in conjunction with staged air, a true staged fuel and staged air effect is achieved. The use of one tip allows for lower NOx production, vastly increased flame stability, and much greater turndown.
