Synterprise’s Ecotube System for NO_x Removal

Synterprise, LLC and ECOMB AB offer the Ecotube System for NO_x reduction and combustion improvement. The Ecotube System consists of two or more retractable lance tubes, located in the boiler furnace above the primary burner zone, for the introduction of high-pressure air as well as ammonia or urea. The very aggressive mixing action created by the Ecotube results in turbulent flow, increased fuel/air mixture residence time, mitigated effects of “reducing atmosphere” corrosion, a more uniform gas flow pattern entering the convection passes, and reduced mass volume solid particle carryover into the convection passes. The water cooled Ecotubes are automatically retracted from the boiler on a regular basis and cleaned to remove layers of soot and other depositions.

Synterprise says NO_x reduction is 60-80 percent, depending upon site conditions and equipment; Ecotube improves boiler efficiency by 1-4 percent; Ecotube can be combined with an SCR system, and installation can be done in 3-4 days. Ecotube also reduces CO and other VOCs and unburned carbon. See www.synterprise.com
