What Can our NOx Solutions Do for You?

When a conventional SCR NOx reduction system is not practical due to space requirements, installation logistics or cost efficiencies, we offer a state-of-the-art combination of technologies and engineering for cost-effective in-boiler NOx compliance.

Primary low NOx measures include our portfolio of cutting edge low NOx burners. LNCFS™ for our OEM boilers, and RFSC™ and RoBTAS™ for other manufacturer's boilers, in combination with our overfire air systems reduce NOx levels by up to 50%.

A secondary reduction of up to 30% of NOx can be achieved with an SNCR (selective non-catalytic converter) system. This works by injecting urea or ammonia in the upper part of the furnace. At temperatures of 1500° to 2010°F the NOx is reduced without the need for a catalyst. 

The GE Umbrella-SNCR (U-SNCR) is unique because the urea is sprayed within the furnace with a nozzle that is adjustable in height. The process uses cooled lances which carry flexible hoses arranged in the furnace. There are no boiler size constraints and the technology is easy to control.
