Boiler Blog | Nationwide Boiler Inc.

Nationwide Boiler is actively monitoring the COVID-19 pandemic and has enacted a semi-remote protocol to help “flatten the curve”. Please understand that we are still fully operational and able to support the many essential industries that we serve, including our hospitals and medical care facilities / suppliers, food processors, petroleum refineries, pulp and paper plants, manufacturing, and electrical power generation facilities. Rest assured that if an emergency need arises and a rental boiler is required quickly, we will be able to fulfill any request as we would on a typical operating basis.

Our sales, engineering and marketing teams are working remote and are fully accessible via email and phone calls. Our accounting team is working diligently to continue the functions necessary for day-to-day operations, and we have a partial shipping and receiving protocol in place with employees available on stand-by if a piece of equipment needs to get serviced and ready to ship out. At our offices, we have implemented additional measures as recommended by the CDC and the federal government, including a higher focus on cleaning and sanitizing commonly touched surfaces and the practice of social distancing. Lastly, we are restricting all non-essential travel and will carefully review and approve any essential travel to continue providing service and support.

We at Nationwide Boiler realize that this global situation affects many business and individuals, and we are here to provide as much support as possible while practicing the necessary measures to slow the outbreak. Our customers depend on us, and we will not let you down even in these uncertain times. We will continue to monitor the situation and provide updates via our social media channels as they arise.

The burner is the key equipment component for combustion control systems, providing the heat required for a boiler to convert water into steam. Ideally, a burner should achieve the highest degree of combustion efficiency with the lowest possible excess air. In this month’s edition of Boiler Basics 101, we will discuss the importance of burners and how they fit into the overall picture within the boiler system.

An industrial burner provides a basic function with a simple concept: it mixes fuel and air together to create combustion. Burners can be fired on various types of fuel but the most common utilized are natural gas, oil, propane and coal. In recent years, facilities have moved away from the use of coal to a more efficient and cleaner fuel like natural gas.

Regardless of the type of fuel used, the burner must perform five functions:

1. Deliver fuel to the combustion chamber
2. Deliver air to the combustion chamber
3. Mix the fuel and air
4. Ignite and burn the mixture
5. Remove the products of combustion

Complete combustion occurs when all combustible elements and compounds of the fuel are entirely oxidized. However, with complete combustion comes harmful byproducts of combustion, including NOx and CO.

The amount of NOx and CO generated depends greatly on the burner design as well as the fuel fired. Burners with uncontrolled NOx may produce 60 ppm or more. Low NOx burners are the current standard and typically produce NOx of 30 ppm. Ultra-low NOx designs have been developed but are limited to firing on natural gas or propane. These types of burners will reduce NOx emissions to as low as 5 ppm to meet strict environmental requirements that are now common in certain parts of the country. If further NOx reduction is required, Nationwide Boiler’s CataStak™ SCR system can be utilized in conjunction with a low NOx burner.

The right burner design, along with proper combustion controls, will maximize the efficiencies of your boiler system. And as a representative of Webster Combustion, Nationwide Boiler and Pacific Combustion Engineering can help in the proper selection of your new or retrofit burner.

Nationwide Boiler’s 2020 trade show tour officially begins next week, and we will be exhibiting at four separate events in the first quarter of the year. We aim to attend multiple industry focused conferences and tradeshows to showcase the many products and services we have available to each industry, and these upcoming events are ones you won’t want to miss.

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.
