Industrial Burners for Energy Efficiency & Low NOx Emissions | Stiefel

Stiefel’s burner atomizers have been designed to enhance fuel atomization in a wide variety of applications. For oil burners, our pressure-swirl atomizers containing tungsten carbide inserts are capable of fine misting (≤30μm) even at heavy fuel oil (HFO) temperatures, lowering the unburned carbon content found in ash from 12% to 4% in a power plant case study. Venturi principles are employed in gas atomizers for turbulent mixing with air; this also resulted in a 35% reduction in NOx emissions for premix burners. In biomass systems, our twin-fluid atomizers overcome problems with highly abrasive self-cleaning nozzles that process pellets (≤2mm) for waste-to-energy plants. All atomizers are verified with flow testing tools within 1% and are compatible with dual fuel burners allowing automatic fuel switching.
