Meeting Peak Season Demand with Rental Boiler Equipment

Tomato season is here, and we already have a 70,000 lb/hr, 400 psi design trailer-mounted rental boiler on location at one of our customer sites to support peak season steam demand. This boiler is rented annually in the Central Valley of California for three to four months during the tomato processor’s short but critical production season. To meet the requirement of 5 ppm NOx, the boiler is supplied with an ultra-low NOx CataStak SCR System. This solution allows the facility to operate their own boilers without overworking them, while complying with local air regulations and satisfying seasonal demand.

Some years ago, the company identified a bottleneck in its evaporation system that hindered peak production capacities. The bottleneck was easily resolved; however, it would take more steam to fully realize the increase in production. Although the existing boilers were capable of running the newly found evaporation capacity, the increased production required the existing boilers to operate at 100% output continuously, leaving no room for margin and no buffer against any process anomalies. After evaluating the cost of investing in a new boiler, the detrimental effects of operating the existing boilers at 100 percent output, and the process vulnerabilities of having no excess steam capacity, the decision was made to rent a supplementary steam boiler on an annual basis.  

Many industries face periods of increased process steam requirements and to satisfy demand, steam can be supplemented with a temporary rental boiler. This practical solution allows facilities to maximize the resources needed to meet current, short-term and long-term steam needs. A short-term or long-term rental solution can save time, conserve capital, minimize risk and maximize available resources.

Check out our past article from Today’s Boiler Magazine to learn more about how temporary boilers can support seasonal steam demand, and contact us today if a rental boiler may be the solution to your peak season needs!

Decarbonization: What Does it Mean for the Rental Boiler Industry?

Decarbonization relates to the reduction or ultimately the extinction of greenhouse gas emissions released into the atmosphere. According to the EPA, Carbon Monoxide (CO2) makes up the vast majority of greenhouse gases released during the combustion of fossil fuels. In addition to CO2, smaller amounts of methane (CH4) and nitrous oxide (N2O) are also emitted during the combustion process. With majority of rental boilers being natural gas or oil fired, what does this mean for the future of rental boilers?

With over fifty years in the industry, Nationwide Boiler has excelled through similar hurdles. In 1995, we became the first and only rental boiler company to convert our entire fleet of watertube boilers to low NOx levels of 30 ppm. In 2001, we started actively utilizing our CataStak™ SCR system on package watertube rental boilers for ultra low NOx compliance, and in 2011 we developed the product further announcing the ammonia-free / urea-based CataStak™ SCR. These and other initiatives were accomplished with sustainability and environmental improvements in mind.

While our CataStak™ and EconoStak fuel efficiency products help the environment by reducing tons of greenhouse gas emissions, we realize the need to consider an alternate non-fossil fuel with the potential to replace the “transitional” fuel of natural gas. Luckily there are some alternate energy solutions available today, including bio-fuels, hydrogen-fired, solar, hydro, and electric.

Keeping up with the Compliance's

As much as we sometimes wish they would just go away, compliance regulations are here to stay.  Overall, regulations are put into place by local governing agencies for the health and safety of the public, environment and plant operations.  These are all items which we agree must be top priority. However, the most difficult part of regulations is interpreting, comprehending, and staying current with new rules, revisions, and updates.  Combine that with the fact that the applicability of regulations can also be daunting -- things just get harder and harder.  

When it comes to NOx compliance, Nationwide Boiler has you covered.  We have helped hundreds if not thousands of customers meet both local and national NOx compliance regulations ever since the Clean Air Act passed in the 1980’s.   Our boiler rental fleet is equipped with the most advanced burners the industry has to offer and our new and reconditioned boilers all include energy efficiency upgrade options and CataStak™ SCR System component add-ons, proven to reduce NOx to levels as low as 5 ppm.

Our most recent compliance success story is a project we recently completed with NRG Energy Center San Francisco.  Nationwide Boiler provided a single Ammonia-Free CataStak™ SCR System for two 55,000 lb/hr natural gas-fired boilers that were required to operate at 9 ppm NOx levels as governed by the Bay Area Air Quality Management District (BAAQMD).

Read more about this project and how it demonstrated a simple method of reducing greenhouse gas emissions without the use of a standard ammonia-based SCR in the fall edition of Today’s Boiler.

If you need help keeping up with compliance's, call us today at 510-490-7100.  We can help.

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.
