One-of-a-Kind Mobile Boiler Room Ready for Service


Nationwide Boiler Inc. and Superior Boiler Works have announced completion of the “world’s first 1,000-hp mobile room”. The one-of-a-kind equipment is now ready for service, the companies said in a press release late last week.

The ASME Section I firetube boiler, ASME spray deaerator, and ASME blowdown separator were manufactured by Superior Boiler Works in Hutchinson, Kansas and required more than a year of custom engineering, planning, and production time.

“The collaboration entailed significant upfront engineering work between the two companies to ensure maximum use of allowable space and operating efficiencies,” said Doug Wright, Superior Boiler’s CEO.

The system is designed at 290 psig, with capabilities for operating pressures ranging from 100 to 260 psig, exceeding other operating pressures available in the marketplace today, Nationwide said. The system is capable of firing natural gas, propane gas, or #2 oil.

A custom 53-foot, four-axle container houses the 1,000-hp boiler and low-NOx, high-efficiency Power Flame burner package, in addition to an ASME spray deaerator and triplex feedwater pumps, ASME blowdown separator, chemical feed system, and oil pump. Nationwide’s standard motor control center panel, with a Honeywell RM7800 burner management system, is also included in the system. Additionally, the system includes an annunciator and a Siemens 353 PID loop controller for parallel positioning combustion control.

The boiler offers an added advantage to customers in Texas. With a heat input of less than 40 million BTUs, no air permit will be required for operation during typical rental use.

“With this product we have pushed the envelope on both size and operating capabilities for a mobile rental unit,” said Larry Day, President & CEO of Nationwide Boiler Inc.

The system will be stored in Kansas for fast delivery throughout the United States.
