Innovation in the Rental Boiler Industry

Nationwide Boiler has been on the forefront of innovation in our industry since 1967. Our founder, Dick Bliss, pioneered the mounting of a 20,000 lb/hr package watertube boiler onto a highway-legal trailer signaling the start of an entirely new business on the West Coast.

The rising of truly mobile rental boilers provided time and cost savings for those in need of temporary steam, as well as a reliable, purpose-built option for rent. Prior to this development, temporary steam supply was sourced from steam locomotives or “jury-rigging” obsolete boilers that had been scrapped. None of these early systems were efficient or easy to get to a job site.

Throughout the years we have continually upgraded and enhanced our offerings and have been a leading innovator in our industry. We were the first rental boiler company to convert our entire fleet to low NOx levels of 30 ppm back in 1995, and in 1999 we demonstrated the first SCR system for ultra-low NOx performance on a package boiler. Just two years later, we began offering our CataStak™ SCR system which has now been installed in over 200 applications.

Today, our product offerings include many one-of-a-kind systems, including the world’s largest mobile saturated and superheated steam boilers. Take a look at the list below for a complete overview of the products unique to our company.

40-75,000 lb/hr Trailer-Mounted, High-Pressure Saturated Steam Boilers
110,000 lb/hr Trailer-Mounted Superheated Steam Boiler (World’s Largest)
125,000 lb/hr Trailer-Mounted Saturated Steam Boiler (World’s Largest)
225,000 lb/hr Skid-Mounted, High-Pressure Rental Deaerators
Complete Mobile Feedwater Vans
Urea- and Ammonia-Based CataStak™ SCR Rental Units
DataStak™ Emissions & Efficiency Monitoring System

Nationwide Boiler is a well-established company that provides reliable, purpose-built rental boiler equipment and a great deal more. As a manufacturer’s representative, we supply new and reconditioned fuel-fired boilers, electric boilers, boiler burners and economizers for sale, and we have boiler systems in-stock and available for immediate requirements. In addition, our proven CataStak™ SCR system is available for ultra-low NOx solutions, and we build custom, PLC-based control systems and fuel skids at our UL-certified fabrication facility in Washougal, WA.

CataStak SCR System Exceeds NOx Guarantee

Nationwide Environmental Solutions is a division of Nationwide Boiler, formed over a decade ago to provide emissions and efficiency solutions to our wide range of customers. In today's day and age, protecting the environment and reducing the production of greenhouse gases is more important than ever, which is why we are so proud to have a product that exceeds expectations time and time again. 

Most recently, we teamed up with MDH Boiler Serviced to supply a food processing facility in Southern California with a new burner and CataStak SCR system retrofit for their existing 475 hp firetube boiler. With lower than typical exhaust temperatures for an SCR application, a more robust system was designed to ensure adequate performance. We are happy to report that the system not only met the guarantee of 5 ppm NOx, but actually exceeded expectations and tested at just 1 ppm NOx and 1 ppm ammonia slip! Exciting news for the team, solidifying future orders that will support the end-user efforts in reducing their company's overall greenhouse gas emissions. Check out our latest press release for the full story.

If your facility is under an air district mandate to reduce the NOx and/or CO output from your boiler or other fired equipment, give us a call at 1-800-227-1966 to learn how we can help.

Boiler Basics 101: Evolution of the CataStak

With air emission regulations constantly changing, Nationwide Boiler has had to adopt new ways to keep up with more stringent standards. For instance, in 1995, Nationwide became the first rental boiler company to convert their fleet of watertube boilers to low NOx levels of 30 ppm. The company’s method of choice to reduce NOx emissions further led to the creation of the CataStak™, which was developed in the late 90s and since then has proven to reduce NOx emissions by as much as 99%. In addition, it can be supplied for new equipment or as a retrofit on an existing system. What were the early days of the CataStak like? What steps did it take to get to where it is now? Let’s find out in this edition of Boiler Basics 101.

It all began when Nationwide Boiler chose Selective Catalytic Reduction, or SCR technology, to be their solution to NOx compliance. They determined that SCR was the best alternative due to its reliability, ease of operation, high efficiency, and its ability to reduce emissions to single digit NOx levels. In 1999, Nationwide Boiler became the first rental boiler company to conduct an SCR field demonstration on a package watertube boiler and followed by utilizing the system heavily in their rental fleet. The enormous success of rental SCR systems suggested to company management that a market existed for a field-retrofit system for package boilers - later to be branded and trademarked in 2001 as the CataStak™ SCR System.

Fast forward to the year 2004, Nationwide began offering the CataStak for new and existing package watertube boilers to meet sub 9 ppm NOx levels. After witnessing its continual growth, Nationwide Boiler introduced a new business unit, Nationwide Environmental Solutions (NES). NES was formed with a focus on lowering overall industrial greenhouse gas emissions and increasing the operational efficiency of fired equipment. This allowed Nationwide to continually raise the bar in providing reliable solutions to meet market demand.

Nationwide later developed the urea-based CataStak as a solution for customers adverse to the stringent handling requirements of ammonia. The system utilizes common diesel exhaust fluid (DEF), a safe and readily available 32.5% liquid urea solution. It was first demonstrated on a package firetube boiler in 2011 and has since been expanded to be utilized on watertube boilers and other fired equipment. Initially, the system was offered only for permanent applications but in 2018, Nationwide became the first rental boiler supplier to provide urea-based SCR systems on a boiler rental project. The company now has a fleet of urea-based SCR systems to support the rental market.

The CataStak has come a long way and has now been installed in over 180 applications. These installations range from temporary to permanent package boilers, fired heaters, gas turbines, and heat recovery steam generators. With all of these accomplishments, the CataStak has become the standard for compliance assurance, reliability and product quality. CataStak SCR systems lead the industry with the best track record in terms of performance, and source test results often exceed current local, regional and national emissions requirements.

6 Tips for Improved Efficiency & Reduced NOx Emissions

75,000pph Rental Boiler with Urea-Based SCR System for Single Digit NOx

Nationwide Boiler's Director of Environmental Solutions, Sean McMenamin, provided content for this month's issue of Process Heating Magazine. The topic of discussion this time around is reducing NOx emissions and improving overall boiler efficiency.

Sean has provided six tips to ensure the highest possible thermal efficiency, and lowest possible NOx output. This includes:

1. Reducing Stack Gas Temperature to Increase Efficiency
2. Managing Excess Air Levels for Optimum Performance
3. Utilizing Flue Gas Recirculation (FGR) to Reduce NOx Emissions
4. Selective Catalytic Reduction for Ultra-Low NOx Performance
5. Combining Economizers & SCR Systems for Emissions & Efficiency Gains
6. Monitoring Emissions & Efficiency Performance

For additional details related to these tips and tricks for reducing NOx and increasing efficiency, check out the full article in Process Heating's September 2018 issue!
