The Ins and Outs of Low NOx Burner Retrofits

　　Low NOx burners are often the go-to-strategy in reducing stack emissions based on several different compelling factors.A28Boiler Burner

　　Burners, in direct comparison to “back-end” solutions – Selective Catalytic Reduction (SCR) or Selective Non-Catalytic Reduction (SNCR) − are usually less costly from a total installed cost standpoint, without having to assume the burden of recurring costs derived from reagent injection and catalyst replacement.A28Boiler Burner

　　Low NOx burners have the added advantage of not requiring additional space/ducting requirements that are often associated with SCR.A28Boiler Burner

　　When combined with SCR, low NOx burners reduce the size of the SCR-related equipment (reagent usage, catalyst quantity and ducting size), resulting in one of the most cost-effective NOx solutions.A28Boiler Burner

　　When placed in head-to-head comparison with many existing burner designs, low NOx burners have significant differences – from different fuel/air mixing designs, internal dimensions, pressure drop requirements, flame geometries and control requirements.A28Boiler Burner

　　All of these need to be thoroughly reviewed and vetted when you’re budgeting, selecting and installing new burners.A28Boiler Burner

　　When considering a burner retrofit project you need to look at not only the burner but also far beyond.A28Boiler Burner
