Suitable for use in package, industrial and utility boilers ranging from single to multi-burner wall-fired, Turbo and other boiler types, the ECOjet ultra-low NOx burners (photo) offer ultra-low (below 30 ppm NOx) emissions with little or no fluegas recirculation. Ignition is achieved using a reliable, self-cleaning and low-maintenance Centronics High Energy Direct Spark Ignitor, a burst-mode ignition with flashing indicator that allows operators to observe the ignitor condition during operation. Staged gas design provides extremely stable flames, up to 20-to-1 burner turndown, hot standby and precise furnace warm-up. Ultra low NOx emissions are achieved on most gaseous fuels (natural gas, propane, refinery gas, landfill gas and off gases), and low NOx emissions are achieved on all liquid fuels (No. 2 through No. 6 fuel oil and ultra-heavy fuels, such as pitch and bitumen). — Hamworthy Peabody Combustion Inc., Shelton, Conn.
