IGS Environmental specializes in comprehensive cleaning solutions. We supply Large Particle Ash (LPA) Screens, Turning Vanes, Air Cannons, and Secondary Screens to a variety of industries and applications. By combining these products to work in unison, we are able to provide customized solutions with unmatched warranty protection.
Large Particle Ash (LPA) Filtration Systems
IGS designs, engineers, and 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 and 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 made with 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 worldwide.
Secondary Large Particle Ash (LPA) Filtration
Secondary LPA Screens are custom-designed separation systems that sit on top of catalyst modules. They provide superior catalyst protection, better air filtration, and enhanced cleaning performance of online cleaning devices. Unlike wire mesh, their smooth surface enables Air Cannons to clean at greater distance and increase the performance of Sonic Horns in eliminating more buildup. The Secondary Screen system is another IGS patent-pending technology. Many coal-fired SCRs are now installing Secondary Screens as original equipment to protect the operation and health of catalyst beds.
Turning Vanes provide a front-line defense against buildup by distributing flow evenly. They are required for many for many applications across several industries. All IGS Turning Vanes are custom-designed with CFD modeling and specifically installed to work in harmony with other cleaning devices. Our Custom Air Cannon Header enables us to keep Turning Vanes clean, even when access is limited.
IGS Blue Air Cannons are blast aerators consisting of a compressed air reservoir with a unique quick opening valve that releases stored air in a sudden, high energy blast. This blast is directed through a discharge pipe to aerate and remove material buildup, and restore process flow.
In an IGS Blue Air Cannon, the air in the reservoir or tank passes directly into the discharge pipe without bends or obstruction in the air. This is important because the quicker the air discharges, the greater the velocity and force of the blast and the greater the amount of material affected.
When used in combination, multiple Blue Air Cannons can restore flow to hundreds, thousands, or millions of cubic feet of process flow. The air cannons can be activated manually, by stand alone controllers or distributed control systems, controlling the firing time interval and sequence of one or more air cannons.
IGS offers two lines of air cannons. The BAC series for general use, and the BAC H.O.T. series for high temperature applications.
IGS Environmental offers a variety of Field Services, such as: turn-key installation service, installation supervision, site inspections, and product management programs. Our Filed Services ensure the equipment is installed, maintained and replaced properly. Customers who employ our equipment and Field Services are eligible for unmatched warranty protection.
When customers contract IGS to provide our solutions for cleaning systems, IGS ensures them with an aggressive warranty protection plan known as the IGS Clean Guarantee. It guarantees a standard of cleanliness and provides compensation if that standard is not met. This protection plane underscores our confidence in our specialized and comprehensive cleaning solutions.
