Technology Overview
In recent years, combustion system owners and operators have relied on Selective Catalytic Reduction (SCR) as well as Low NOx burners (LNB) and Ultra-Low NOx burners (ULNB) to reduce emissions. Unfortunately, each of these options introduce operational and financial challenges. For example, SCR’s are highly capital intensive, sometimes costing many millions of dollars in acquisition, infrastructure and operational costs to accommodate and support the needed systems. As for ULNB and LNB’s such systems use long flame length to cool flame temperatures to combat NOx formation. Such long flames can impinge upon the surface of the process tubes degrading performance and requiring additional maintenance and production interruptions.
ClearSign’s Duplex Technology solves all these problems, dropping NOx emissions to unprecedented low levels while increasing fuel efficiency and process throughput, ushering in a new era of economically advantageous environmental compliance.
Duplex eliminates potential flame impingement.Duplex essentially turns a single large and unruly flame into thousands of tiny, more easily controlled flames. Duplex burner architecture controls and reduces flame length and offers a number of potential improvements to operations, including:
- Reduced operating costs: no external flue gas recirculation, no high O2 levels and/or no selective catalytic reduction.
- Increased thermal capacity: heaters may be fired at higher rates to optimize total plant output.
- More complete mixing: a more balanced fuel/air blend to virtually eliminate NOx-forming species.
- Reduced maintenance costs: less de-coking, lower failure rates and longer lifetimes.
