Advantages of Renting a Mobile Boiler Room

Temporary steam will be necessary at some point in the lifetime of a boiler, so boiler owners should be prepared and know what rental boiler options are out there. Let’s review one of the most convenient rental boiler types available on the market today: The Mobile Boiler Room.

Mobile Boiler Rooms come in a wide range of sizes, typically ranging from 50 to 1,000 hp with design pressures of up to 290 psig. They are completely pre-piped and wired and incorporate all necessary auxiliary equipment for a functioning mobile steam plant. This typically includes a feedwater system, duplex water softener, chemical feed system, blowdown separator, and motor control center. Some units are dual-fuel fired, while others are natural gas only to achieve ultra-low NOx emissions compliance. In addition, Nationwide Boiler maintains multiple units that are pre-permitted for use in the SCAQMD to help simplify the air permitting process for our customers.

Mobile Boiler Rooms are often utilized in heavy commercial and industrial applications for added capacity or for supplemental steam. Some of the main advantages to this type of system include:

   - A Mobile Boiler Room is permanently mounted to a highway-legal trailer, so there is no time lost locating a suitable trailer
     for transportation.
   - Being permanently mounted to a trailer also avoids the need for cranes for loading and un-loading, saving both time and money.
   - Mobile Boiler Rooms are completely enclosed and fully weatherproof – no need for temporary enclosures.
   - No expensive and time-consuming foundations are necessary. Only a reasonably level surface is required.
   - All the necessary auxiliary equipment is included, pre-piped and wired. This saves valuable field time and expense.
   - Customers only connect the steam, fuel, water, and electricity drains, everything else is assembled and ready to go.

A Mobile Boiler Room is the closest you can get to a “plug-and-play” rental boiler system. They provide a packaged temporary steam plant that can be up and running in hours if an emergency need arises.  In fact, units have been installed and operational in just eight hours after arrival.

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.

Innovative Leaders: Virtual FAT Testing

Nationwide Boiler is known as being an innovative leader in the rental boiler industry. Over fifty years ago we pioneered the mounting of a 24,000 lb/hr package watertube boiler to a highway-legal trailer, and followed with many other firsts including the world’s largest trailer-mounted saturated and superheated steam boilers (125,000 lb/hr and 110,000 lb/hr, respectively).

In this age of digital technology and pandemic isolation requirements, Nationwide Boiler’s control division, Pacific Combustion Engineering, realized the need for virtual factory acceptance testing (FAT). An FAT is an essential element of the testing and acceptance of new critical control systems. The main goal of this test is to prove and certify performance built for a specific application and ensure all design requirements are attained.

Pacific Combustion’s new test gear consists of a 19” HMI that replaces toggle switches, indicating lights, potentiometers, and analog gauges. A PLC drives relays and consists of contacts that can be configured for the voltage that is required for input simulation. Outputs are displayed via selectable 120vac and 24vdc terminals. Analog 4-20ma inputs are selectable as either loop or self-powered.

During the virtual FAT, a web portal is accessible by the client through an audio/video link to the testing, and the client can actually operate the test rig HMI screen from their location. Links are also furnished to the burner management / combustion control system PLC and HMI.

This is a truly unique innovation at a time where travel can be difficult, providing an alternative to the traditional FAT and allowing business to continue even in heightened times like a global pandemic.

For more details on our virtual FATs, be sure to check out our upcoming feature in Process Heating Magazine. We will post the direct link as soon as it's available. And be sure to give Pacific Combustion Engineering a call to assist with your next control system upgrade. 360-335-1443

Preventing Freeze Damage This Winter

It's that time of year again for our annual freeze protection reminders. As you know, winter can bring extremely cold weather conditions, especially in Canada, the Northeast, Midwest, and Upper Midwest. To reiterate what we have been saying for years, here are a few things to consider to protect your rental boiler and auxiliary equipment (deaerators, water softeners, etc.) from damage due to freezing temperatures this winter.

1. If you are renting a trailer or skid-mounted firetube or watertube boiler and installing the unit outdoors, these systems are completely exposed to the environment. User's should consider enclosing the front and/or the rear end of the boiler, or build a temporary enclosure around the entire system. An external heating source should also be used. 

2. Install the proper heat tracing (steam or electric) and insulation on all main lines and piping components, regardless of whether the boiler (or auxiliary equipment) is in operation or sitting as stand-by. This should include the following lines: 
      - Sensing lines for all transmitters
      - Primary and auxiliary low-water cut-offs
      - Water column and connected piping
      - Bottom blowdown and surface blow-off piping, depending on the length of the piping runs. These valves should also be left open.
