The GLSF Enhanced Jet Flat Flame burner design offers the following advantages:
No flame rollover
Superior heat flux profile
Superior low NOx emissions
Compact design that may be retrofit into existing furnaces
Low initial cost
Low maintenance costs
Superior NOx Emissions
The Zeeco GLSF Enhanced Jet Flat Flame burner uses internal flue gas recirculation to lower NOx emissions. As the primary gas burns, inert products of combustion are generated (see figure below). The secondary gas passes through the primary gas' product of combustion, forming a diluted fuel composition that is burned next to the furnace wall. The secondary gas burns over the region in which the primary gas is burning—resulting in combustion at a reduced peak flame temperature and thermal NOx production.
Since the GLSF design does not have a metal flame stabilization device in the burner's throat, the burner size is relatively small. The advantages of smaller burner external dimensions are:
Easy retrofit - Since the external dimensions of the burner are smaller, it can normally replace conventional NOx and staged-fuel NOx burners with only minor furnace modifications.
Reduced cost - Since the burner is smaller than other ultra-low NOx designs, the cost of material and labor is lower. Zeeco passes these savings on to our customers.
GLSF Enhanced Jett Flat Flame Description
The GLSF design incorporates internal flue gas recirculation to lower NOx emissions and to provide improved heat flux characteristics. In addition, the GLSF Enhanced Jet Flat Flame burner has small external dimensions, making it easy to retrofit into existing furnaces.
