The Power Flame Type EVO Combustion Burner has an innovative design with “Patent Pending” staged/premix combustion technology to maximize operating efficiency and reduce NOx emissions on natural gas firing below 30 PPM without the use of flue gas recirculation (FGR). Designed to fire a range of gaseous fuels and light oil, the EVO burner utilizes a unique firing head design that provides stable combustion over a 6:1 turndown. The combination of operating at 3% excess oxygen and sub 30 PPM NOx revolutionizes the burner market. Currently available from 40 to 1500 BHP, the EVO will fire on a wide range of boilers and heat exchangers.
