Cleaver-Brooks ProFire SBR-30 low-NOx, dual-fuel burner series is capable of less than 30 ppm NOx emissions without flue gas recirculation (FGR). It features a unique firing head design to achieve controlled combustion, leading to low emissions with 3% O2, low-NOx, low CO emissions, and up to 10:1 turndown on natural gas. These features pushed this series of burners to the top of our list, as our panel of engineering judges selected it as the 2021 Commercial Comfort Product of the Year award winner in the Heating Equipment category.
“There are numerous benefits created through the elimination of FGR,” said Kevin Pheney, vice president, burner systems, Cleaver-Brooks. “Elimination of the need for FGR in high-stack-temperature steam boilers will reduce energy efficiency by 0.5%-1.5%, extending the turndown and minimizing on-off cycling. FGR pipes are massive and space-consuming, and they generate extensive energy loss in the boiler room. All of this can be eliminated with the SBR-30 non-FGR solution, also extending turndown up to 10:1 on natural gas applications.”
