 Zeeco GLSF Free-Jet burners are used for applications where the lowest NOx emissions or Next Generation Ultra Low NOx burners are required. These burners are designed to be very compact for easy retrofit and low emissions. In general, these burners are smaller than most staged fuel type burners and other Next Generation burners while providing much lower NOx emissions. In general, these burners are used for applications where NOx emissions in the 15 ppmv to 30 ppmv range are required, depending upon the operating conditions. This type of burner can be provided with bottom air entry or side air entry configurations. The burner can be used in natural or forced draft type applications and typically each burner is provided with an individual plenum. The standard burner is designed to achieve a noise level of 85 dBa, but if required, much lower noise levels can be achieved by designing with alternative materials. Typically, these burners are designed to achieve a 5:1 turndown or greater. The Free-Jet series of burners has set the industry standard that other companies try to match. This revolutionary burner design is protected by U.S. Patent # 6,499,990.

 Zeeco GLSF Free Jet hearth burners may be utilized when extremely low NOx emission levels are required for a flat flame type burner. The burners can be designed to fire against the furnace wall and/or free-standing, where the burner is mounted in a location where the burner is fired in the open away from the wall. By maximizing the amount of inert products of combustion with the fuel gas, amazing ultra low emissions can be achieved in an extremely small footprint. In general, these burners are used for applications where NOx emissions in the 15 ppmv to 30 ppmv range are required, depending upon the operating conditions. This type of burner can be provided with bottom air entry or side air entry configurations. The burners can be used in natural or forced draft type applications and typically each burner is provided with an individual plenum. The standard burner is designed to achieve a noise level of 85 dBa, but if required, much lower noise levels can be achieved by designing with alternative materials. Typically, these burners are designed to achieve a 5:1 turndown or greater. This revolutionary burner design is protected by U.S. Patent # 6,499,990.

 Zeeco GLSF Min Emissions burners are used where low & ultra-low NOx emissions are required. This is our most popular burners designed to be very compact for easy retrofit and low emissions. In general, these burners are smaller than most staged fuel type burners while providing much lower NOx emissions. Min Emission burners are used in applications where NOx emissions in the 25 ppmv to 40 ppmv range are required, depending upon the operating conditions. The Min Emission burner can be provided with bottom air entry or side air entry configurations. The burners can be used in natural or forced draft type applications. Typically each burner is provided with an individual plenum, but there are also versions available for mounting in a common plenum. The standard burner is designed to achieve a noise level of 85 dBa, but if required, much lower noise levels can be achieved by designing with alternative materials. These burners are designed to achieve a 5:1 turndown or greater. This innovative burner design is protected by U.S. Patent # 6,394,792.

GLSF Min Emissions / Enhanced Jet Flat flame burners are used
for ethylene cracking applications. Our most popular burner
for hearth fired applications. This flat flame burner is offered
in both gas only and combination oil and gas configurations.
The combination oil and gas version is referred to as the Model
CLSF. These burners utilize our proven low emission technology
for superior performance verses conventional and previous generation
Low NOx burners. These burners were designed to achieve incredibly
low NOx emissions while providing better heat flux; and most
importantly, well defined flames that do not roll back into
the tubes. These burners are used for applications where NOx
emissions in the 35 ppmv to 70 ppmv range are required for high
temperature applications, depending upon the operating conditions.
This type of burner can be provided with bottom air entry or
side air entry configurations. The burners can be used in natural
or forced draft type applications. Typically each burner is
provided with an individual plenum, but there are also versions
available for mounting in a common plenum. The standard burner
is designed to achieve a noise level of 85 dBa, but if required,
much lower noise levels can be achieved by designing with alternative
materials. Typically, these burners are designed to achieve
a 8:1 turndown or greater.

 Zeeco GB Series burners are used for conventional NOx emissions type applications where low cost, good flame quality and great turndown is required. Depending upon the actual operating conditions, these burners typically are used for applications where the NOx emissions can be approximately 100 ppmv or greater. This type of burner can be provided with bottom air entry or side air entry configurations. The burners can be used in natural or forced draft type applications. Typically each burner is provided with an individual plenum, but there are also versions available for mounting in a common plenum. The standard burner is designed to achieve a noise level of 85 dBa, but if required, much lower noise levels can be achieved by designing with alternative materials. Typically, these burners are designed to achieve a turndown greater than 5:1.

 Zeeco has a full range of burners for cracking furnaces including our RW series low emission pre-mixed radiant wall burner. The Zeeco low emission RW series burner utilizes an advanced venturi design, a customized gas tip and secondary fuel gas injection to achieve very low NOx emissions. It does this without creating flame interaction or flame flashback problems. Additionally, Zeeco offers a forced-draft version of the RWSF burner. These burners mix the fuel and combusion air at the tip. The burners can operate under pre-heated or ambient air.
