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.)

At Nationwide Boiler, we are known for our relationship with B&W as a partner and stocking distributor. The FM-120-124 B&W D-Type Package Watertube Boiler, also known as our “World Boiler”, is always in stock and has been sold to six of the seven continents in the world. In recent years, we have ramped up our stock boiler program to also include new Superior firetube boilers in a variety of configurations.

To start off, we added two specialized, factory integrated packages. These 47.5 hp and 119 hp skid-mounted package boilers are pre-piped and wired and include a duplex feedwater system and blowdown separator with after-cooler. The 47.5 hp boilers are pre-certified for use in the most stringent California air districts, while the 119 hp packages are PEER compatible for both the SCAQMD and SJVAPCD jurisdictions. Our 475 hp, 150 psi design Superior skid-mounted firetube boiler, equipped with a Webster 7ppm NOx burner, is also ideal for customers in the most stringent areas of California. All three of these systems are currently available from our shop in Fremont, CA. 

To round out our stock inventory of pacakge firetube boilers, we now have the following brand new Superior boilers available for quick ship and immediate needs: 

• 200 hp, 200 psig Skid-Mounted Firetube Boiler
• 300 hp, 250 psig Skid-Mounted Firetube Boiler
• 350 hp, 250 psig Skid-Mounted Firetube Boiler
• 700 hp, 250 psig Skid-Mounted Firetube Boiler
• 800 hp, 250 psig Skid-Mounted Firetube Boiler

These stock boilers are pre-built with the burner left purposely un-mounted to allow for greater flexibility in matching the unique fuel, emissions, and combustion needs of each customer. The burner can be quickly mounted prior to delivery or installed at the site, based on customer preference. The boilers are designed for indoor and outdoor applications, with most currently being stored at the manufacturing facility in Hutchison, KS. All units are now available for immediate shipment upon customer request.

We also have our very first, zero emissions electric boiler now available for rent or for sale. This boiler, built to provide 50 hp steam at a design pressure of 150 psig, is another one of our factory integrated units, with feedwater system and blowdown separator pre-piped and wired as a skid-package.

In addition to the new boilers that we purchase specifically for our stocking program, our fleet of rental boilers and auxiliary equipment range in size and in age. We are always open to providing a solution from our rental fleet as well, if the opportunity arises. Be sure to check out or complete inventory of boilers available for sale to find a unit that fits your unique needs. 

Please give us a call at 800-227-1966 if you have an immediate boiler need that can be fulfilled from our stock of brand new boilers, reconditioned boilers, or equipment from our rental fleet.

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.

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.
