Development of Industrial Low NOx Burner

BURNER TECHNOLOGY FOR SINGLE DIGIT NOx EMISSIONS IN BOILER APPLICATIONS

The local air quality districts in the Los Angeles area were the first to implement restrictions to require that NOx emissions on natural gas fired boilers be reduced to single digit levels. Now additional states are being required to develop State Implementation Plans (SIPs) to address bringing into compliance the areas that do not meet the ozone standards set forth in the Clean Air Act Amendm...

Low NOx Combustion Technology for Minimizing NOx

A noble low NOx combustion technology, based on partial oxidation combustion concept in a fuel rich combustion zone, is successfully applied in this research. The burner is designed such that a portion of fuel is heated and pre-vaporized in the furnace then injected into a fuel rich combustion zone so that a partial oxidation reaction occurs. The effects of equivalence ratio, thermal load, and ...

Simulation of Nitrogen Emissions in a Low Swirl Burner

We present simulations of a laboratory-scale low swirl burner fueled with hydrogen at atmospheric pressure. The study uses detailed chemistry and transport including a submechanism for computing nitrogen emissions. The simulation shows how the cellular burning structures characteristic of lean premixed hydrogen combustion lead to enhancements in the NOx emissions from these flames. Analysis of ...

Interaction of turblence and chemistry in a low-swirl burner

New combustion systems based on ultra-lean premixed combustion have the potential for dramatically reducing pollutant emissions in transportation systems, heat, and stationary power generation. However, lean premixed flames are highly susceptible to fluiddynamical combustion instabilities, making robust and reliable systems difficult to design. Lowswirl burners are emerging as an important tech...
