Meeting Peak Season Demand with Rental Boiler Equipment

Tomato season is here, and we already have a 70,000 lb/hr, 400 psi design trailer-mounted rental boiler on location at one of our customer sites to support peak season steam demand. This boiler is rented annually in the Central Valley of California for three to four months during the tomato processor’s short but critical production season. To meet the requirement of 5 ppm NOx, the boiler is supplied with an ultra-low NOx CataStak SCR System. This solution allows the facility to operate their own boilers without overworking them, while complying with local air regulations and satisfying seasonal demand.

Some years ago, the company identified a bottleneck in its evaporation system that hindered peak production capacities. The bottleneck was easily resolved; however, it would take more steam to fully realize the increase in production. Although the existing boilers were capable of running the newly found evaporation capacity, the increased production required the existing boilers to operate at 100% output continuously, leaving no room for margin and no buffer against any process anomalies. After evaluating the cost of investing in a new boiler, the detrimental effects of operating the existing boilers at 100 percent output, and the process vulnerabilities of having no excess steam capacity, the decision was made to rent a supplementary steam boiler on an annual basis.  

Many industries face periods of increased process steam requirements and to satisfy demand, steam can be supplemented with a temporary rental boiler. This practical solution allows facilities to maximize the resources needed to meet current, short-term and long-term steam needs. A short-term or long-term rental solution can save time, conserve capital, minimize risk and maximize available resources.

Nationwide Boiler Steamlines Newsletter: Available Now!

Nationwide Boiler's first Steamlines Newsletter of 2021 is out and available for viewing! Read up on the latest happenings at Nationwide, industry news, technical tips, and more, including... 

A SOLUTION TO STEAM SUPPLIER OUTAGES
Nationwide has nearly 55 years of experience responding to emergency needs, and there is no doubt that we are able and ready to dispatch equipment in a moments notice. What may come as a surprise to some is that unplanned and emergency rentals make up a smaller portion of our business than planned outages. And at times, rental boilers are used for process steam when the outage is planned by the steam supplier next door.

REMOTE WORK: IS IT THE FUTURE?
Since the pandemic forced many companies (including NBI) to move to a temporary remote work model, some corporations like Google, Dropbox, Facebook, and Salesforce are going all in with remote work as a permanent way of business. But is remote work for everyone, and is it the future? Hear from our President & CEO, Larry Day, for his take on the matter.

GETTING TO KNOW OUR STORAGE YARDS
Nationwide Boiler has a purpose built rental fleet featuring firetube and watertube boilers, mobile steam plants, and boiler auxiliary equipment. Partnering with multiple distinguished companies in our industry for the storage & maintenance of this equipment allows us to offer a quick and cost effective solution when a temporary steam need arises.

CALIFORNIA EMISSION RULE UPDATES
More changes are upon us here in California, and at Nationwide Boiler we make it a priority to stay abreast of AQMD emission rulings that will affect our customer base. The three areas of focus at this point are the South Coast AQMD, San Joaquin Valley APCD, and San Diego APCD.

REP SPOTLIGHT: COMBUSTION SYSTEMS, INC.
With headquarters in Indianapolis, IN, Combustion Systems, Inc. (CSI) is the exclusive Nationwide Boiler representative covering the territories of Indiana, Illinois, and most of Wisconsin. Check out this edition of our representative spotlight to learn more.

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.

The Cost of Renting a Boiler

The rental boiler industry is unique and operates nowhere near the e-commerce business model; you may find it near impossible to find and compare pricing online. With that said, how can a user understand the potential cost of renting a boiler in the preliminary stages of their project, before they are ready to start reaching out and gathering information and pricing from vendors?

To get you started on the journey, these six major costs categories should be considered when looking at renting a boiler.

Equipment. Your process, as well as the steam capacity requirement, will often dictate which type of boiler is best fit for your operation. A watertube boiler, often best for larger capacity needs, will run at a higher cost than a firetube. If additional equipment is required like a deaerating boiler feedwater system, water softener, or SCR system for reduced emissions, additional costs will be realized.

You can save on costs if you are able to connect to existing auxiliaries, however, that is not always an option. A mobile boiler room, which includes a firetube boiler installed with a feedwater system, water softener, and blowdown separator, is a convenient option for customers needing an entire steam plant. Because it is a complete, pre-piped and wired system, the cost would be higher than that of a boiler-only option.

Freight. Often coordinated and re-billed by the rental boiler supplier, this will be a separate cost billed after each time the equipment moves (from the storage facility to your site, and then back to the storage facility). Costs will vary based on number of shipments required and how far the boiler must travel. Some companies, like Nationwide Boiler, have multiple maintenance yards to help facilitate quick and lower-cost shipments.
 
Installation. This is a piece of the process that is typically coordinated by the end-user and with a third-party supplier. Installation costs can vary greatly depending on the size of a project. The cost to install a mobile boiler room for a temporary project, as close as you can get to a “plug and play” system, would likely be much lower than the cost to install a large watertube boiler. Watertube boilers are more commonly installed in industrial applications along with economizers, SCR systems, and ductwork – heavy equipment that requires forklifts and/or cranes for installation.
 
Start-up. Most often, your rental boiler vendor will supply a technician for start-up with costs billed on a time and material basis. It’s important to ensure that the equipment is completely ready for start-up with all utilities piped and available, to reduce extra time costs. You will also want to consider any time required for site-specific safety training.
 
Utilities. Obviously, the utilities are the responsibility of the end-user, however, it is an expense that should not be overlooked. You will incur costs associated with the fuel, water, and electricity required to produce steam. Rental economizers and blowdown heat recovery systems can be utilized to help reduce these costs.
 
Water Treatment. This is an extremely important part of maintaining a rental boiler, and if not done properly can lead to extreme costs for equipment repairs. The cost of contracting with a water treatment supplier will be much less than what it would be to replace or repair damaged rental boiler equipment.
 

Ultimately, reaching out to your supplier of choice and obtaining a detailed proposal will be the best way to understand all costs involved with renting a temporary steam plant. Call or email your trusted Nationwide Boiler sales representative for a detailed cost proposal at 800-227-1966 or info@nationwideboiler.com.
