Nationwide Boiler Inc., the previous pioneer of the world’s largest trailer-mounted mobile boiler, has now begun production on a new “World’s Largest Mobile Boiler.” The previous unit was a 120,000 lb/hr, 400 psi design saturated steam boiler, which was an active part of Nationwide Boiler’s rental fleet for the last ten years before being recently sold to a brewery in the Southeast. This newest boiler will surpass the previous capacity for the largest trailer-mounted mobile boiler ever built, representing another new industry first by Nationwide Boiler Inc.

The new 125,000 lb/hr low NOx O type boiler is being built by Babcock & Wilcox and will be mounted on a custom 6 axle low boy trailer. Designed at 750 psig, the boiler will provide a wide range of operating pressures for saturated steam applications from 250 psig to 675 psig. The boiler will be equipped with a low NOx natural gas / future oil burner, FD fan and TEFC motor with VFD, fully metered combustion controls, a NEMA 4X panel, EconoStak economizer, stub stack and all flues, ducts and valving. An optional CataStak SCR is available for down to 2.5 ppm NOx requirements. The boiler system is scheduled to be ready for service this fall and will be available for shipment worldwide.
