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.

Enhancing BMS Safety with the use of PLC-based Controls

Combustion equipment safety is essential for the daily operation of facilities and safety of plant personnel. Safety protocols and mechanisms in industrial plants have improved drastically in the last century, but incidents still occur far too frequently. Because boiler systems are inherently dangerous, safety must be factored into the design of not just the boiler, but also the burner, combustion control, and the overall operation of the system.


The burner management system (BMS) is just one of many safety devices built into a boiler system, designed to control the combustion process from beginning to end in a safe and reliable manner. It monitors high and low gas pressure, the combustion air fan, combustion air, and water levels, in addition to monitoring safety devices and controlling the sequence of lighting the burner. If any issues arise related to pressure or water level, it will initiate closure of the shut-off valves. To automate these processes, PLC-based controls are often used as a BMS. PLC based BMS gives you much more flexibility, the ability to use analog input signals as limits, limit voting and the versatility to have almost unlimited safety limits.


A Programmable Logic Controller (PLC) is a robust computer utilized for industrial automation. Although a PLC doesn’t physically look like a typical computer, it incorporates the very same technology seen in computers and smart devices that we use every day. The PLC receives information from connected sensors or input devices, processes the data, and triggers outputs based on pre-programmed parameters. It consists of a power supply, a CPU (central processing unit), input and output cards, and communication cards. A programming device (often a laptop computer) is utilized for writing programs into the PLC and HMI (human machine interface) which provides a visual model of the system as a whole.


Compared to traditional technologies, a PLC-based system is easier to troubleshoot, more reliable, more cost-effective, and much more versatile. In addition, PLC-based controls provide added levels of safety for the burner management system and overall operation of your boiler. PLCs are built in compliance with NFPA 85 and SIL2 requirements at minimum and can be configured to meet SIL3 standards as well. Therefore, we are seeing boiler control panels being built or updated to PLC-based systems more than ever.


Pacific Combustion Engineering has extensive knowledge and experience in the design, build, and programming of PLC-based combustion control systems. If you are in the market for an upgrade or brand-new panel that incorporates PLC, give us a call and we will design a system that fits your unique process needs.

New 110,000 lb/hr Superheat Boiler Provides Increased Steam Capacity

With short summers and weather as unpredictable as it is charming, much of Newfoundland and Labrador relies on NARL Refining’s ability to provide warmth and clean fuel. We were able to assist with the refinery’s needs by providing them with one of our new in-stock 110,000 lb/hr trailer-mounted superheat boilers. The 750 psig design watertube boiler was manufactured by Babcock & Wilcox, who recommended Nationwide Boiler for the job per our stock boiler program.

To learn more about the boiler sale and how we were able to accommodate the customer’s need for an immediately available unit, read our latest case study. (PDF will download in a new window.)

Representing New Product Lines

Nationwide Boiler and Pacific Combustion Engineering have been busy this holiday season, adding additional brands to our current list of reputable manufacturers that we represent.

For the states of California and Nevada, Nationwide Boiler has signed on to represent E-Tech Heat Recovery Systems. For the states of Washington, Oregon, and part of Idaho, Pacific Combustion Engineering has signed on to represent Superior Boiler, Webster Combustion, and E-Tech Heat Recovery Systems. Part of Montana is also included with the E-Tech representative agreement.

First off with the Superior Boiler line, we are able to offer customers with high quality Scotch Marine firetube boilers ranging in size from 10 hp to 2,500 hp. Webster Burner builds high tech and cost effective multi fuel burners for commercial and industrial type boilers. Lastly, E-Tech Heat Recovery Systems fabricates fuel efficient solutions that also reduce exhaust pollutants. Products include a variety of economizers, steam generators, waste heat boilers, and more.

Each of these industrial equipment manufacturers have a long standing, reliable product that we as a company are confident standing behind. We are excited to begin the new year with these companies and look forward to a prosperous 2018!
