Maintenance and Refurbishment of Rental Boilers

As with any heavily utilized piece of equipment, rental boilers often return to our shop in need of service. Not every rental requires major repairs, but every unit goes through a standard inspection and maintenance process before being returned to service. Our skilled technicians perform routine tasks such as gasket and valve replacements, tube brushing, burner tune-ups, and safety control testing to ensure each system meets the high quality standards we’ve set over the years. These preventative and corrective measures address normal wear and tear that naturally occurs over the course of a rental. Having a disciplined approach to maintenance helps us minimize future service calls, ensure performance reliability, and reduce the total cost of ownership for our customers.

In rare cases, a unit may be damaged beyond repair and must be retired from service. However, thanks to our experienced fabrication team and dedicated Quality Control Department, most boilers are restored and returned to service in like-new condition. With proper maintenance, boilers can provide reliable performance for decades.

Why Retube a Boiler?

A complete boiler retube is one of the most effective ways to extend the life of a heavily damaged boiler, particularly in demanding industrial environments. Over time boiler tubes naturally wear down due to constant use, high temperatures, and exposure to impurities in the water. However, the lack of proper maintenance and water treatment can quickly accelerate this, leading to major damage to the internal boiler tubes and creating an immediate need for retube or complete system replacement.

When boiler tubes become corroded or damaged, overall performance, efficiency, and safety can decline, causing costly downtime or even system failure. Retubing restores the boiler’s internal components, significantly improving efficiency and returning the system to like-new condition.

A Commitment to Reliability, Sustainability, and Performance

At Nationwide Boiler, we take pride in our ability to perform quality service and maintenance on our rental fleet, as well as refurbish and repurpose equipment whenever the need arises. Retubing not only extends the useful life of our boilers but also plays a key role in our sustainability efforts. Instead of scrapping boilers that still have a solid pressure vessel and frame, we focus on restoring their core components. This approach reduces waste, conserves resources, and helps us maintain a high-quality, cost-effective rental fleet.

Our commitment to maintaining a high-performance rental boiler fleet ensures that our customers receive dependable, code-compliant, and cost-effective steam solutions every time. Whether you need a short-term rental for a few weeks or a long-term solution for several months, Nationwide Boiler has the equipment, expertise, and service to keep your operations running smoothly.

This blog post was originally published in June 2021 and has been updated to reflect the latest advancements in boiler maintenance, sustainability practices, and the continued expansion and modernization of Nationwide Boiler’s rental fleet.

Boilers are important components in many industrial settings and ensuring their longevity and efficiency requires proper maintenance, even during out-of-service periods. To prevent corrosion and other forms of damage when a boiler is offline, it is important to protect both the fireside and waterside of the boiler. There are two methods in achieving this – the dry method and the wet method.

Dry Storage

When a boiler is expected to be out of operation for an extended period of time and needs to be ready for service quickly, dry storage is advised. The dry storage method for industrial boilers involves draining, thoroughly cleaning, drying, and sealing the boiler to prevent moisture and air entry during extended periods of inactivity.

NOTE: If you are placing your boiler in storage for less than one month, follow steps 1 and 2 only. Be sure to follow your company guidelines and, at a minimum, label it as an oxygen-free atmosphere.

The following general procedure is advised for placing a unit into dry storage:

1. Shut down and secure the boiler. Once the pressure decreases to 20 psig, drain the boiler and header valves under air. Once the pressure is reduced to 0, open the drums to allow air to circulate and facilitate the drying of all internal surfaces.

2. If the unit is cold and filled with water, drain it under air, blow out non-drainable tubes with compressed air, and use external heat sources to aid in drying internal surfaces. Install non-porous trays with moisture absorbent (preferably silica gel) into the drums, ensuring they don't touch the drum's metal surface. Use at least one pound of absorbent per 1,000 pounds per hour of steam capacity.

3. Attach nitrogen to the steam drum vent, close all other vents, and pressurize the boiler to reach 10-15 psig with nitrogen, adjusting the amount based on the unit's volume.

4. With the boiler and superheater pressurized, alternately open all drains to purge air until the pressure drops to zero, repeating as needed to minimize oxygen levels.

5. The unit should now be stored with a nitrogen pressure of 5-10 psig in the steam drum. To maintain this pressure, ensure all connections and valves are sealed or tightly closed, and check the gas pressure daily for proper protection.

6. Boiler inspections are recommended every 3 months to ensure no corrosion is occurring and to replenish the absorbent as needed. During these inspections, air will enter the unit so you will need to repeat steps 3 and 4 to expel the air.

Wet Method

Wet storage prevents corrosion by keeping the boiler fully submerged with the right chemicals. Volatile chemicals are recommended to avoid increasing dissolved solids in the water.

The following general procedure is advised for placing a unit into wet storage:

1. Fill the boiler with deaerated, demineralized water treated with 200 ppm hydrazine and enough ammonia to reach a pH of 10.

2. Pre-mixing chemicals with water is recommended, using the blend-fill method to ensure uniform distribution in the boiler. Simply adding chemicals through the drum manhead may not adequately disperse them unless the boiler is heated to induce circulation.

3. Fill the unit with treated, demineralized water up to the normal centerline of the steam drum, then stop the filling process.

4. Refill the superheater with treated demineralized water until the steam drum level rises. Keep filling until water starts to flow from the steam drum vents. Once the filling is complete, make sure all connections are securely sealed.

5. Attach a low-pressure nitrogen source to the steam drum to maintain 5 to 10 psig and prevent air from entering the unit during storage.

6. When the boiler is ready for use, drain the superheater and the boiler drum to the normal start-up water level and resume operation.

7. Analyze the treated demineralized water weekly and add chemicals as needed through the chemical feed line to maintain recommended levels. Water samples can be collected from the continuous blowdown line or a suitable drain.

8. A boiler should not be stored wet if there is any risk of temperatures dropping to freezing, unless adequate heating is provided. Adequate heating will prevent water from freezing and avoid damage to the pressure parts.

Protection of External Surfaces:

Protection of external surfaces is also necessary during periods of extended downtime. Fireside corrosion in idle boilers can cause damage to components due to sulfuric acid from flue dust and ash. To mitigate this, remove deposits using air blasting, washing, scraping, or brushing, and neutralize any residual acid with alkaline water until the water is fully neutralized. Once flushing is complete, fill the boiler with treated water and fire it with low sulfur fuel to ensure complete drying.

Auxiliary heaters and blowers may be needed during storage to keep the metal temperature above the dew point and prevent freezing, especially with wet storage in cold conditions. Additionally, protect machined surfaces with preservative coatings and ensure there are no fuel leaks by disconnecting all oil and gas connections.

The choice between dry and wet storage depends on different factors. Although wet storage is often preferred, factors such as water quality, weather conditions, storage duration, and heat availability may make dry storage a more practical option. Be sensible when considering the conditions and needs of your boiler and choose the best storage method to ensure your equipment remains in excellent condition and is ready for use when needed.

Last month Nationwide Boiler hosted our 43^rd Annual Charity Golf Tournament at the renowned Pebble Beach Golf Links and it was another great success! Drawing in participants from across the nation, the event gathered a diverse and enthusiastic crowd ready to support two great causes.

The tournament kicked off with a practice round and a scramble competition at Poppy Hills Golf Course, where the golfers enjoyed pleasant sunshine throughout the day. As evening approached, golfers and guests gathered for a welcome reception to enjoy drinks and appetizers, socialize, and purchase tickets for the highly anticipated raffle for 1 oz. of gold. Our tournament round took place the following morning at Pebble Beach Golf Links followed by a Hawaiian Luau themed awards banquet and buffet dinner later in the evening.

At the awards banquet, guests donned floral Hawaiian attire with real orchid leis while enjoying live island music by the Ho ‘Omana Trio. Guests also participated in online and live auction events as well as our unique Deck of Cards Raffle.  Don Thiry was our big winner that night, taking home the raffle prize of 1 oz. of gold in addition to having the winning card for the Deck of Cards Raffle! However, in a surprising twist of events, he sold his winning card for $200 and the remaining $800 prize was generously donated back to the charities. These acts highlight the sportsmanship and goodwill that make our tournament special.

In addition to the fun and fundraising activities of the banquet that evening, Nationwide Boiler’s President and CEO, Larry Day, announced the winners of the tournament. Matt Whittington of Hurst Boiler took home the Callaway Flight Championship, Mitch Frank of HTS took home the Handicap Flight Championship, and Geoff Wilkinson Jr. of GT Wilkinson Companies took home the Low Gross Championship. Nationwide Boiler’s Jack Valentine took home the award for Closest to the Pin, and, for the first time in the history of this tournament, Longest Drive was awarded to a women golfer, Emily Forth of Tulsa Heaters Midstream.

With the aim of benefiting two impactful causes, Make-A-Wish® Greater Bay Area and ABMA’s Randy Rawson Scholarship Fund, the tournament was a resounding success with a total amount raised exceeding $63,000! This achievement was made possible by the support of roughly 100 attendees and the generous contributions of nearly 60 sponsors and donors. Nationwide Boiler is proud to continue raising funds for these two great organizations, and we extend heartfelt gratitude to everyone who supported the event this year.

Make-A-Wish® Greater Bay Area is all about making dreams come true for children facing critical illnesses, giving them unforgettable experiences and much-needed hope.  This chapter serves 17 counties in Northern California and has granted over 9,500 wishes to date, providing approximately 350 life-changing wishes each year.

We look forward to another incredible tournament next year!

National Safety Month, observed each June, is an annual campaign that is dedicated to raising awareness about the leading cause of preventable injuries and deaths. Sponsored by the National Safety Council (NSC), this month-long event is focused on enhancing safety in homes, workplaces, and communities through education and advocacy. By emphasizing proactive measures and fostering a culture of safety, National Safety Month aims to protect lives and promote well-being across the nation.

In alignment with the NCS’s approach, Nationwide Boiler will also be dedicating each week of June to a specific safety topic and strives to share this information to a wider audience. Last week we focused on ergonomics in the workplace.

Ensure Proper Posture: Maintaining correct posture is crucial for safeguarding your back. Many individuals tend to slouch or hunch over their desks while working without realizing it. While seated, maintain a natural slight arch with your back, ensuring your head and shoulders remain erect. If necessary, customize your chair to have relaxed elbows, comfortable hand placement on the table or desk, knees bent at a 90-degree angle, and feet flat on the floor.

Establish An Ergonomic Workplace: The work environment significantly influences your comfort and musculoskeletal well-being. It is important to remember not to adapt your body to the workplace, but to tailor your workspace to accommodate your body. Make sure your computer screen is positioned at eye level to eliminate the need for leaning forward. Invest in ergonomic office equipment engineered to offer back support and encourage correct posture.

Incorporate Regular Breaks: Make sure to take regular breaks during your workday to boost productivity and overall well-being. Set aside a few minutes every hour to get up and do some light stretching exercises. You can start by placing your hands on your lower back and gently arching backward to relieve tension. Additionally, consider taking short walks to the break room, another spot in your remote workspace, or around the office to break up your sitting time.

Work In A Comfortable Position: Whenever possible, position your work materials at waist height to reduce strain. Arrange your workspace to keep essential items easily accessible and within reach. Another option is using adjustable furniture and workstations to accommodate varying needs and preferences for a comfortable working posture.

Prioritize Safe Lifting: To prevent strain on your back, refrain from bending or twisting when lifting objects. Instead, bend your knees and keep your back straight when lifting items from the floor to ensure safe handling. It is important to seek assistance when handling heavier loads or utilize lifting aids to reduce strain and minimize the risk of injuries.

Selection Of Tools: Go for tools equipped with ergonomically designed handles that feel comfortable to hold, thus reducing strain during extended use. Selecting the appropriate tool for each task not only boosts efficiency but also lowers the chances of experiencing repetitive strain injuries and discomfort.

As we wrap up our focus on ergonomics, we emphasize the importance of caring for your body by creating a comfortable workspace for long-term health and productivity. Nationwide Boiler prioritizes the safety of our employees and will continue to share valuable insights to foster a safe culture. Celebrate National Safety month with us and stay tuned for another safety topic next week!
