"However, with the new regulations on the horizon and the inability of conventional Low-NOx burners to meet the new emissions criteria cost effectively," Rutkowski said, "many operators are being forced to consider SCR. We believe that the market will be at an inflection point over the next two to five years that makes the timing of our innovation especially good."
"In the longer term," Colannino added, "we believe that our Duplex burner architecture may be able to reduce NOx to levels that are not attainable using conventional technology. We are already close to exceeding even the most aggressive environmental standards for NOx control in the world, and we are continuing to push this number even lower. Moreover we are achieving these results without the costly compromises in fuel efficiency that have historically plagued Low-NOx designs."
According to the Company, the Duplex burner architecture may enable significantly reduced flame length (by as much as 80%) improving flame pattern, while dramatically reducing NOx emissions. The Duplex architecture may be highly extensible and could have significant implications across a broad range of commercial applications that utilize a variety of burner sizes and types. Key features of the duplex architecture include:
•Ultra low NOx emissions - 5PPM demonstrated with a target of 2PPM or lower.
•Short flame - allows for maximum utilization of available heater capacity enabling increased process throughput for high-value applications such as refinery heaters. Short flames are not possible with currently available technology without increasing NOx. The loss of heater capacity can represent an annual cost of tens of millions of dollars annually at an average refinery.
•No External FGR - Currently available Low- Ultra-Low NOx burners often require recirculation of up to 35-40% of flue gas. Reheating this gas is inefficient. This loss in energy efficiency is compounded by the requirement to provide power for large fans to recirculate the gas.
•Low O2 (excess air) of 2-3% - Currently available LNBs and ULNBs often require significant increases in excess air (in extreme cases up to as much as 8 to 10%). This imposes a penalty to energy efficiency as the cool inlet air continuously dilutes furnace gas.
•High turndown ratio - Unlike currently available LNBs and ULNBs, the Duplex burner architecture may support very high operating ranges allowing for maximum energy efficiency under variable operating conditions and requirements.
