Boiler Basics 101: Common Rental Boilers on the Market

The boiler rental business began over fifty years ago, solving multiple industries’ need for temporary and emergency steam. Nationwide Boiler was at the forefront of the boiler rental industry, starting off with one of the first mobile rental boilers; a 20,000 lb/hr, 300 psig design, O-type package watertube boiler. This boiler was designed for permanent use on a highway-legal open deck trailer, making it a true mobile boiler. This new idea allowed companies to cut capital costs, save time, and be more efficient in their operations. Now, rental boilers are available for small-scale projects to industrial sized applications.

In last month’s edition of Boiler Basics 101, we discussed why rental boilers are a great choice for boiler owners in a variety of industries. To continue the topic, we will now discuss the different types of rental boilers currently on the market.

Trailer-Mounted Boilers

  • - Permanently installed on highway-legal trailers for easy transport by truck
  • - Boilers of various sizes up to 125,000 lb/hr, both saturated and superheated steam
  • - Detachable goosenecks and booster extensions allow for easy removal when space is limited
  • - Not protected from the weather and precautions must be taken for freeze protection (heat tracing and insulation or temporary housing shelters)
  • - Separate feedwater and water treatment systems and other auxiliaries can be provided to support the boiler, as needed

Skid-Mounted Boilers

  • - Shop-assembled package boilers, without any true mobility
  • - Available in capacities up to 250,000 lb/hr
  • - Depending on the size of the boiler, skid-mounted boilers can be transported on a flat-bed trailer, step-deck trailer, or by rail
  • - Cranes and/or forklifts typically required for both loading and offloading
  • - Not protected from the weather and precautions must be taken for freeze protection (heat tracing and insulation or temporary housing shelters)
  • - Separate feedwater and water treatment systems and other auxiliaries can be provided to support the boiler, as needed

Containerized Mobile Boilers

  • - Typically includes a package firetube boiler, installed inside a container and mounted on a chassis for mobility
  • - Ideal for users who need a boiler-only package that is weatherproofed for outdoor operation in the wintertime
  • - Separate feedwater and water treatment systems and other auxiliaries can be provided to support the boiler, as needed

Mobile Boiler Rooms

  • - Complete steam plants, self-contained within enclosed vans, with all equipment required to produce steam:
  •          * Package firetube boiler
  •          * Atmospheric feedwater system
    •          * Water softener
    •          * Chemical injection tank
    •          * Blowdown separator
  • - Typically available in capacities up to 1,000 hp
  • - Weatherproofed and better suited than alternatives for outdoor operation in the wintertime

Mobile Steam Plants

  • - Similar to a mobile boiler room, with all equipment required to produce steam
  • - Equipment is installed on an open, step-deck trailer
  • - Not protected from the weather and precautions must be taken for freeze protection (heat tracing and insulation or temporary housing shelters)

Transportable Steam Plants

    • - Complete steam plant, normally built inside of a standard 20 or 40’ shipping container
    • - Available with either a vertical or a horizontal boiler arrangement depending on requirements
    • - Cranes typically required for both loading and offloading
    • - These systems accommodate less capacity than a mobile boiler room
    • - Popular for overseas and government projects, due to ease of transportation

Each type of rental boiler system explained above has their own unique advantage and may be better fit for one user over another. The requirements of operation, however, are the same: end-users must supply a fuel source (natural gas, #2 oil, propane, or other fuel), electrical power supply, and make-up water. Which type of rental system is best fit for your unique operation?

Nationwide Boiler maintains an inventory inclusive of all types of boilers listed above, ranging in size from 47.5 hp to 200,000 lb/hr. Visit our website to find a complete listing of rental boilers available, and contact a Nationwide Boiler Sales Representative for additional details and pricing. 1-800-227-1966

Discovery ChalleNGe Academy Visits Nationwide Boiler

IMG 9604

Located in Lathrop, CA, the Discovery ChalleNGe Academy is a Community High School run by the California National Guard in partnership with the San Joaquin County Office of Education. Part of the National Guard Youth ChalleNGe Program (NGYCP), the Academy was founded in 1993 to assist students in enhancing life skills, education levels, and employment potential.  This military-style program houses, feeds, and educates 16 to 18-year-old young adults that were unable to complete high school due to varying unfortunate circumstances. The program allows students to earn 65 High School credits while developing leadership, job, and academic skills, while improving self-esteem, pride, and confidence.  


With the school year coming to an end and graduation quickly approaching, The Academy set up a trip for a group of students working to complete their high school credits, and Nationwide Boiler was honored to participate. The goal of this field trip was to educate the graduating class on the many different education, trade, and career opportunities available to them once they step out into the real world.

The first stop of the day was San Jose State University, where they toured the campus and the new $130M recreation center. After experiencing lunch like a college student in the Student Union, they headed north to Nationwide’s shop in Fremont. Upon arrival, the students congregated on the patio to hear a warm welcome from President & CEO, Larry Day, and Vice President, Michele Tomas. The group was then taken on a tour of our 26,000 sq. ft. shop, where day-to-day activities include; boiler maintenance, welding, painting, electrical work, fabrication, equipment assembling, and other technical skills.

Nationwide Boiler’s Shop & Service Managers, Andrew Horne and Michael Rosmando, educated the students on the basics of a boiler system, and walked them through the different trade skills and career opportunities available not just here at Nationwide, but from other companies in similar and varying industries. Many of the students were interested in welding, electrical, and accounting careers. Who knows… we may have just met future Nationwide employees!

At Nationwide Boiler, we feel strongly about training and educating our youth so that we are able to successfully sustain our business and industry for future generations, and we are happy to have had the opportunity to be a part of this inspiring program. Thank you to Todd Robinson and the NGYCP for providing young adults with an opportunity that will help them secure their futures.

Happy International Women's Day from Nationwide Boiler!

womens day

At Nationwide Boiler, we are proud that we are able to break the barriers in a male-dominated industry, by employing valuable, hard-working women throughout many departments. We believe that all of the women at Nationwide Boiler make a big impact on who we are and what we stand for as a company. Hear from some of the Women of Nationwide about their pastimes and how they feel they make an impact:  

Michele Tomas - VP Finance
"The tides of the boiler industry are shifting, where more women are being recognized for their valuable contributions to organizations that serve the needs of steam generation. As a leader at Nationwide, I feel empowered to have my voice, as well as others, heard within the organization. Our skills and inputs are not only recognized, but are known and credited as vital inputs to the ongoing success of the company."                                       

Holly Lepo - Quality Control & Facilities Manager
“Because of my years of service and the numerous job positions that I have held, I have had a unique opportunity to see how Nationwide has grown in terms of Women in the workplace. From a time when we had Women only in clerical positions to now when we have many Women in management, accounting, engineering, marketing, and quality control. I have had the honor of working closely with and getting to know most of our Women.  It is wonderful to see how Women have advanced into the Working Women of today.

One of my favorite outside activities is to hop in my RV and venture out with my Women’s group, friends, and family.  Of course, at one time it would be quite unusual to see a Woman driving, maintaining, and setting up an RV by herself!”

Chelsey Ryker - Marketing Manager
“I enjoy being part of the small group of working women in the boiler industry, and I appreciate the many opportunities for growth that I have received at Nationwide. It’s nice to work for a company that promotes a work-life balance, with flexibility that allows me to be a working mother of two. And as a woman that is part of the leadership team, I feel empowered to provide new ideas that will help improve processes and day-to-day activities throughout the company.”

Shalini Kumar - Senior Accountant
“I feel that I have made an impact at Nationwide in many ways since I started working here in January 2018. I have made processes more clean and organized, and I have made many employees in the company feel that I am a “go-to” person. They know that I will definitely try to assist them or guide them to the appropriate person. I always try to be positive and have a smile on my face, in hopes of bringing a smile to others in the company and allowing them feel comfortable approaching me.”

Sandy Nevels - Shop Admin
“I feel that I make an impact working at Nationwide by always be willing to do whatever it takes to get my tasks done quickly and efficiently.

I enjoy being part of a team and I am always willing to help out my co-workers when needed. People often come to me with questions about certain work topics and I direct them to the proper person to which they can get the answer, or I volunteer myself to assist. You can say I’m helpful and a go-to person. Although I am Holly’s admin,  I also enjoy assisting the shop, service, and other departments throughout the company when needed.

When I’m out of the office for an extended period of time, I am told that I was missed and that people are glad that I’m back, which makes me feel valued. I always come to work with a positive mindset and try to make each day the best it can be.”

Ruthy Brand - Office Admin
“I like volunteering, cooking, travelling, and spending time with my family and friends. In fact, this coming Saturday, I am volunteering for my second year with California Dental Association (CDA).  Twice a year they provide free dental works for Northern California and Southern California residents.”

The women at Nationwide Boiler truly are remarkable and appreciated every day. Celebrate International Women’s Day and don’t forget to tell the women around you how much you appreciate them.

Why Rent a Mobile Boiler Room?

There are many different types of boiler options available in the rental market. Trailer-mounted boilers, skid-mounted boilers, transportable steam plants, and of course, mobile boiler rooms.

Mobile boiler rooms are highway-legal, transportable trailer-mounted vans or containers, designed and customized to house the components of a “mini” steam plant. This includes all of the necessary equipment with the proper hook-ups to supply a given amount of steam for most any application. Major equipment typically contained within a complete mobile boiler room includes a low NOx boiler, feedwater system, duplex water softener, chemical feed system, blowdown tank, and all valving and controls required for complete steam room operation. Typical mobile boiler rooms operate on natural gas, #2 oil, or propane, and range in size from 47.5 hp to 1,000 hp with design pressures from 150 to 290 psi.

What makes a mobile boiler room advantageous for end-users is that they require no special foundations, are fully enclosed, and can sustain inclement weather conditions without the use of costly weather protection. In addition, mobile boiler rooms are aesthetically pleasing in both industrial and commercial settings.

Nationwide Boiler has provided thousands of customers with high quality mobile boiler rooms that have not only met high steam demands, but have also required quick delivery, rapid start-up, and ease of operation. In most instances, a mobile boiler room requires one knowledgeable operator with proper training on boiler control safety and feedwater quality control. Industries that utilize mobile boiler rooms range from hospitals, food processors, pulp and paper plants, colleges and universities, and light manufacturing, just to name a few.

When deciding if renting a mobile boiler room is best for you, the following factors must be determined:

Boiler Steam Capacity. Since mobile boiler rooms are designed to fit into a highway-legal, trailer-mounted container or van, the boiler design must be considered. Nationwide Boiler’s 1,000 hp mobile boiler room tests the limits in design and capacity by utilizing a 53’ long, 4-axle trailer. This unit can produce 34,500 lbs/hr of steam and can operate up to 270 psi. If additional steam capacity is required, multiple units can be considered. As an alternative, a large trailer-mounted watertube boiler with separate mobile feedwater van can be rented.


Location.
Mobile boiler rooms are fully enclosed units and can be transported to any facility as long as proper electrical and utility hookups are available. Mobile boiler rooms are more operational and more secure than skid-mounted systems. This enables mobile boiler rooms to be utilized in public locations with decreased operational noise disturbances and possible tampering of exposed boiler equipment.

Ease of Operation. Mobile boiler rooms are designed to be fully operational steam plants, without the need of a full-time boiler control team. As long as daily boiler and feedwater quality logs are kept, and required maintenance is performed, then costly teams of operators can be avoided.

The evolution of mobile boiler rooms continues to expand and Nationwide Boiler is committed to supplying the right equipment for your needs. Contact a Nationwide sales representative today to determine if a mobile boiler room is the right choice for you.
