ULTRA LOW NOx BURNERS
Ultra Low NOx burners provide industrial boiler owners with the ultimate solution to their NOx compliance needs. Each system application is specifically designed to maximize NOx 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 NOx formation. NOx reductions can range from 40% to 60% depending on the fuel type.
HOW FUEL TECH'S ULTRA LOW NOx COAL BURNERS REDUCES NOx EMISSIONS
Fuels being fired range from sub-bituminous through low and high sulfur eastern bituminous coals. NOx 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
