Description Paper from the AFRC 2015 conference titled Ultra Low NOx Conventional and Regenerative Burner Retrofits
Abstract The first section of the paper will focus on cold/hot air burner conversions to Ultra low NOx hot air burners. It will be illustrated that a cold air burner can often be retrofitted to an Ultra Low NOx hot air burner with minimal or no change in NOx emissions, despite the increase in air temperature. In addition, it may be possible to make changes to the burner internals only in order to make the conversion. The paper will illustrate retrofits from hot air to Ultra low NOx hot air burners. To make these changes, furnace manufacturers would require little or no modification to the furnace wall opening to accommodate the new burner.; The second section of the paper will focus on Regenerative burner conversions. Because regenerative burners are fired in pairs, the perception may be that twice as many burners are required to replace existing conventional burners. However, an increase in burner capacity, furnace circulation, and efficiency may allow the actual number of burners to even be reduced. Ultra low NOx regenerative retrofits are also possible using the latest Regenerative CyclopsTM technology. With the regenerative CyclopsTM Burner, NOx emissions are reduced by nearly a half as compared to market leading regenerative burners.
