As stack emission regulations become more and more demanding, plant facilities will often seek the lowest possible emissions to meet or exceed the newest standards. There are two options currently available to lower NOx emissions: front-end burner technology and back-end selective catalytic reduction (SCR) technology. 

Nationwide Boiler’s CataStak™ SCR system was originally tested and utilized in our boiler rental fleet, and is now offered for both rent and for sale to lower NOx on many different types of fired equipment. 

What is a CataStak™ SCR?

Nationwide Boiler developed the CataStak™, a low-temperature SCR system capable of reducing post combustion NOx emissions by as much as 95%. The CataStak SCR system consists of a single-reactor housing with low temperature catalyst and an ammonia (aqueous or anhydrous) or urea (diesel exhaust fluid) injection skid. 

How Does it Work?

The CataStak SCR system is typically located between the flue gas exhaust and the economizer. As the flue gases exit the boiler, they are routed through the ammonia injection grid to the SCR housing with DeNOx catalyst. As the gases exit the housing, the NOx is released as nitrogen and water. 

One unique feature of our CataStak SCR system is that the catalyst that we supply facilitates the reaction of NOx and ammonia, allowing the reaction to occur at a lower temperature.

Why Choose a CataStak™ SCR System?

Three key advantages of the CataStak SCR system include easy field retrofit, low operating cost, and minimum operator intervention. When installing the SCR system, there is no need to change out burner controls or the fan, providing a simple installation and a major cost savings. Additional cost savings and increased efficiency are seen due to better turndown, lower O2, and reduced motor horsepower without FGR. Lastly, the CataStak can operate independently causing less boiler trips and less interference with plant operations.

With our CataStak SCR system, Nationwide Boiler can guarantee results as low as 2½ ppm NOx @ 3% O2, which is well below all current state implementation plan levels. Being able to achieve 2½ ppm NOx will give your plant peace of mind for any future changes to emissions regulations. The CataStak delivers exceptional performance, reliability, and compliance assurance. 

With over eighteen years of experience, a 100% success rate and over 120 installations, we have more experience and satisfied customers than any other competitor for boiler SCR systems. In addition to selling the system, Nationwide Boiler is an active user of the CataStak on our rental fleet for ultra low NOx boiler requirements.

The CataStak SCR system is available as an add-on for existing and new package boilers, gas-fired turbines, refinery heaters, and for other demanding combustion applications. Contact us today to learn how you can decrease your facility’s operating costs and lower your carbon footprint with a CataStak SCR system.

Eastern US Business Manager Jim Barbeau is currently in Pittsburgh, PA representing Nationwide Boiler at CIBO’s Boiler Operations, Maintenance & Performance Conference.

This year marks 35 years for the Council of Industrial Boiler Owners (CIBO) bringing industry professionals together to discuss the latest industry trends and learn about improved technologies for improving operations, sustainability, efficiency and overall plant performance. With forums organized for specific groupings, this year's show agenda allows for maximum interaction between participants with similar equipment and concerns. 

As a proud member of CIBO, Nationwide Boiler is an operator, owner and supplier of boiler equipment worldwide. Check out our booth at the show today and tomorrow to see our wide variety of options available for your temporary and permanent steam needs.

What Is an Economizer?

Economizers are mechanical devices intended to reduce energy consumption or perform a useful function such as preheating a fluid. In basic terms, an economizer is a heat exchanger. The orientation of an economizer can be vertical, horizontal, or cylindrical depending on boiler size and space available, and it is fitted directly to the boiler near the flue gas outlet.

How does it Work?

In a boiler system, an economizer captures the heat of the flue gas and transfers it to the feed water. The process is simple. As the flue gas exits the boiler, it enters an economizer with finned tubes. The finned tubes absorb the heat and raises the temperature of the boiler feed water, lowering the needed energy input.

Why Add an Economizer?

Adding an economizer will increase boiler efficiency by 10-12%. In addition, the reduced amount of energy required for heating results in reduced fuel consumption and cost.

Nationwide Boiler’s EconoStak Economizers

A Nationwide Boiler EconoStak consists of the economizer and all of the associated piping and structural supports required for very efficient and safe operation. It is a fabricated assembly of finned tubing that uses hot stack gases to heat the boiler feed water. The EconoStak economizer reduces stack emissions and thermal pollution, as well as provides fuel cost savings. It can be can be utilized with one of Nationwide’s trailer-mounted rental boilers, or can be purchased with a new or reconditioned boiler.

Join us this Thursday for Nationwide Boiler's first ever webinar, hosted by Director of Sales, Bill Testa, and Latin America Business Manager, Jaime Cubillos. 

In this informative webinar, Bill and Jaime will review key considerations for industrial, commercial, and utility plants in Mexico that are highly dependent on reliable steam supply. Topics presented will include:

  • Critical planning stages for incorporation of a temporary steam plant
  • Delivery lead-time measured in days for rapid response
  • Specific plant requirements and site considerations for tie-in of a rental boiler
  • Provisions for balance of steam plant equipment such as economizers, deaerators, feed pumps, blowdown separators, water softeners, gas regulators, etc.
  • What is required for feedwater treatment
  • What guarantees should be expected from a rental boiler supplier
  • Boiler rental risk mitigation and management

Rapid industrialization and growing energy demand in Mexico requires consistent and reliable steam supply for production processes, heating, and power generation.Industrial boilers at energy facilities are expected to provide an uninterrupted supply of steam, often on a 24/7 basis. Loss of steam translates to lost production or lower efficiency of facilities dependent on steam for heating. Steam interruptions can also result in forced outages or shutdowns for which plants must have contingency plans in place.

Energy facilities that require a reliable steam supply must consider alternatives to mitigate steam interruptions through an emergency preparedness plan. Mobile or temporary steam plants, trailer-mounted watertube boilers, and package boilers provided on a rental, lease-buy or purchase arrangement represent a low cost and quickly deployable solution to maximize plant reliability & availability.

Nationwide Boiler Inc. has a large inventory of temporary rental boilers available for immediate shipment worldwide. Our rental fleet consists of mobile boiler rooms from 47.5 hp to 1,000 hp, trailer-mounted boilers from 30,000 lb/hr to 125,000 lb/hr, and other boiler related equipment. In addition, we currently have Package Babcock & Wilcox Watertube Boilers from 75,000 lb/hr to 200,000 lb/hr located in Monterrey, Mexico. These boilers are in stock inventory and available for immediate purchase and delivery. 

Register for the webinar today to learn more about what Nationwide Boiler can offer to the Mexico boiler market.
