CataStak™ SCR – Best Option for System Upgrades
In February of this year, the Boiler MACT rule was published in the Federal Register, causing the Environmental Protection Agency (EPA) to propose new regulations calling for system upgrades on boilers and auxiliary equipment in many plants. The costs associated with these upgrades can reach up to $35 billion according to the EPA, but because the costs will be specific to each individual plant, no one will know the real costs until the boiler equipment is evaluated to comply with new and future regulations. Boiler operators are hesitant to spend the money due to the uncertainty of regulations, but eventually something will need to be done.
There are resources available, and the U.S. boiler and combustion equipment industry is readily able to meet the demand for these system upgrades. Randy Rawson, President of the American Boiler Manufacturer’s Association (ABMA), said, “We have the workforce resources to meet the needs of our customers, as long as our customers don’t push compliance go the last minute.”
The largest air districts in California have passed rules that require NOx compliance as low as 5 ppm by the year 2015. Few burner manufacturers have been successful with developing new ultra low NOx (ULN) burner technology that easily and safely performs at 9 - 7 ppm NOx. Many users that have tried ULN burners suffer the consequences of high FGR or excess air rates that compromise not only efficiency, but also the operational limits of boiler equipment, resulting in limited turndown capabilities, flame pulsations and unstable operation.
Today, selective catalytic reduction (SCR) technology has taken over as the best available control technology for complying with ultra low NOx emission requirements. Nationwide Boiler, having invested in SCR technology for our rental fleet over the last ten years, has both the experience as an user and a supplier of the CataStak™ SCR system. Our SCR systems have met or exceeded emission requirements for over one hundred boilers, steam generators and gas turbines installations.
The Nationwide Boiler CataStak™ SCR system is proven to decrease emissions, increase energy efficiency, reduce fan horsepower and provide greenhouse gas / carbon reductions. Typical users can save significant energy costs by reducing flue gas recirculation which substantially reduces fan horsepower (HP) and when compared with a typical 9 ppm burner, fan HP can be reduced by as much as half.
If you are concerned or have questions about how your facility is planning to comply with local air quality regulations, send am email to firstname.lastname@example.org and together we can come up with a solution that can perform as low as 2.5 ppm NOx and pass any current air regulation with the lowest carbon footprint.
