Air Pollution Control - Low NOx Burners

AIR POLLUTION CONTROL Low NOx Burners (brochure)

Ultra Low NO_x burners provide industrial and utility boiler owners with the ultimate solution to their NO_x compliance needs. Each system application is specifically designed to maximize NO_x reduction without sacrificing combustion performance or unit operation. Computational Fluid Dynamics (CFD) combustion modeling is used to validate the design prior to fabrication of equipment. Lean combustion zones are created for deep staging. These zones inhibit the formation of NO from fuel bound nitrogen in coal and oil fired burners. In gas burners the peak flame temperature is reduced to limit thermal NO_x formation. NO_x reductions can range from 40%-60% depending on the fuel type.

How Fuel Tech's Ultra Low NO_x Coal Burners Reduces NO_x Emissions

Fuels being fired range from sub-bituminous through low- and high-sulfur eastern bituminous coals. NO_x reductions exceeding 50% from baseline levels can be achieved across the load range with minimal increases in unburned carbon.

Features include:

Ease of operation
Patent pending five (5) zone burner
Balanced perimeter airflow
Homogeneous coal flow
"Clean release" coal nozzle
Accurate secondary airflow measurement

Mechanical Attributes:

Ceramic Lined Inlet Elbow
Ultra Low NO_x Swirler
Ultra Low NO_x Coal Nozzle
Insulated Front Plate
Ceramic Lined Coal Barrel with 309 SS tip
Venturi Low NO_x Register Assembly with Flow Control
Ceramic Lined or AR400 Coal Distribution Disk
