Proprietary LPA Filtration – NoNOx Components™

IGS designs, engineers, manufactures the longest lasting large particle ash (LPA) filtration systems in the world. Typical filtration screens protecting catalysts within SCR systems have proven to be short-lived and unreliable, resulting in frequent clogging of catalyst with LPA (or “popcorn ash”), decreasing NOx reduction performance. In contrast, IGS’s NoNOx Components™ patent-pending systems have been in service for years in some of the most aggressively run SCR systems in the world, having maximized catalyst maintenance cycles, reduced the likelihood of unplanned downtime, and significantly reduced the lifetime cost of SCR systems.

The NoNOx Components™ system features an optimized, custom-fit screen and support system design and proprietary erosion-resistant materials that outperform any other commercially available LPA screen system. Additionally, IGS’s in-house engineering, flow modeling, and system design experience provide SCR systems designers and owners the opportunity to maximize their systems’ open area ratio (OAR), decrease pressure drop, conserve fan power consumption, and improve ash collection. With over 50 successful installations, the NoNOx Components™ system represents a complete, cost-effective turnkey procurement package for utilities and architectural and engineering firms in the U.S. and around the world.
