Benefits of a Skid-Mounted Boiler

Compact Footprint
Because skid-mounted boilers do not require a trailer chassis, wheels, or additional housing, they maximize boiler capacity while minimizing space requirements. This streamlined design makes them ideal for facilities with limited installation space, allowing higher steam output in a smaller footprint.

Cost-Effective for Long-Term Projects
Skid-mounted boilers are often the most economical option for extended rental periods. While crane, rigging, and transportation costs may be required during installation and removal, these expenses can be offset by lower rental rates compared to trailer-mounted units. For long-term outages, plant expansions, or temporary capacity needs, skid-mounted boilers can provide significant overall cost savings.

Flexible Installation Options
The compact design allows skid-mounted boilers to be positioned in locations where trailer-mounted systems may not fit, helping facilities optimize site layouts and maintain operational efficiency.



Project Spotlight - Dynegy Moss Landing, LLC (Formerly Duke Energy & PG&E)

One of the largest fossil fuel-based electric power generating facilities in the U.S. is operated at Moss Landing, California. Two oil-fired boilers provide steam to two steam turbines which, in turn, drive two 750 megawatt generators. When a system is taken offline for maintenance, superheat steam is required during the system restart.

Occasionally, both boilers that provide steam to the two turbines at the Moss Landing facility must be taken offline at the same time.  When this occurs, an auxiliary steam supply capable of providing 700°F steam is needed to pre-heat the system and draw a vacuum on the condensers.  Because of the strict environmental standards, emissions produced by any boiler used for this purpose must not exceed 25 ppm NOx and 50 ppm CO.

A 55,000 lb/hr, 700°F steam skid-mounted package boiler rental was available in stock at Nationwide Boiler's Fremont, California facility.  Although this boiler had sufficient capacity and met the steam temperature and pressure requirements, it did not meet the current NOx and CO emission limits of the Monterey Bay area at the time. The boiler was retrofitted with a new low NOx burner. After installing the new burner, the boiler was fully tested at the Nationwide Boiler test facility.

Because of the salt-air environment and since plans called for using this boiler only twice each year on average, special protection was provided. This protection consists of all NEMA 4X electrical enclosures and panels, Sealtite conduit, special priming and exterior paint, and a dry nitrogen blanket system that maintains a positive pressure of 10 inches of water inside the boiler. The protective inert-gas environment is used whenever plans call for a boiler to be out of service for an extended period.

Nationwide Boiler delivered the complete, fully tested boiler system with the low NOx burner. The boiler was installed with the support of Nationwide Boiler technicians and was available for service whenever needed to support start-up procedures. Actual emissions fell well below the required limits. Third-party source tests confirmed levels of 15 ppm NOx and 10 ppm CO at full-load conditions.


 
Skid-Mounted Boiler FAQs 
What is a skid-mounted rental boiler?
A skid-mounted rental boiler is an industrial steam boiler mounted on a structural steel skid rather than inside a trailer. These boiler rentals are designed for transportation to customer sites and are commonly used when facilities require higher steam capacities, customized installations, or long-term temporary steam generation. Skid-mounted rental boilers are a flexible solution for planned outages, plant expansions, and emergency steam requirements.

When should I choose a skid-mounted boiler rental instead of a mobile boiler room?
Skid-mounted boilers are often selected when a facility requires greater steam output, integration with existing plant systems, or a customized installation. Compared to trailer-mounted units, these rental boilers can provide greater flexibility for long-term projects, facility upgrades, and applications where site access or space limitations require an alternative boiler rental solution.

Are skid-mounted boiler rentals available for emergency projects?
Yes. Skid-mounted boilers can be deployed to support emergency outages, boiler failures, unexpected increases in steam demand, and critical plant operations. Nationwide Boiler provides fast-response boiler rentals, along with transportation coordination, installation support, and startup assistance to help facilities restore steam production as quickly as possible.

What industries use skid-mounted boiler rentals?
Skid-mounted boiler rental systems are used across a wide range of industries, including refineries, petrochemical plants, food and beverage processing facilities, chemical manufacturers, pulp and paper mills, power generation stations, hospitals, universities, and industrial manufacturing operations. These boiler rental solutions help facilities maintain reliable steam generation during outages, maintenance projects, and capacity expansions.

Can emissions controls be provided with a skid-mounted boiler rental?
Yes. Many boiler rentals can be equipped with low NOx or ultra-low NOx combustion systems to meet local air quality regulations and project-specific emissions requirements. Nationwide Boiler offers rental boiler solutions designed to help customers meet both operational and environmental objectives.

Can skid-mounted boilers be integrated with existing plant equipment?
Yes. Skid-mounted boiler systems are frequently incorporated into existing steam plants and can be connected to deaerators, feedwater systems, economizers, and other plant equipment as required by the application.
