    Nationwide Boiler Inc., representative and stocking distributor of Babcock & Wilcox (B&W) package watertube boilers, recently secured their largest rental project in their fifty-one year history. The company will supply three (3) 200,000 lb/hr, 750 psi design / 750F superheated steam, skid-mounted B&W package watertube boilers for a project at the new Saudi Aramco Jizan Refinery. The boilers were complete, in-stock, and available for quick ship opportunities, purchased as part of Nationwide Boiler’s equipment stocking program. In addition to the boilers, a plant master workstation and one (1) deaerator tank with pumps will be provided for the duration of the rental.

    “We are pleased that Saudi Aramco has entrusted Nationwide Boiler with this large and complex rental boiler project. Having three high capacity watertube boilers complete with immediate availability was key in securing the order, but a significant amount of preparation, multiple discussions to formulate an offering that fit their needs best, and a committed team with “all hands-on deck” is really what sealed the deal. This multifaceted rental will require continued collaboration between our project manager, export logistics and transportation company, and the customer, and we are looking forward to a successful project,” stated William Testa, Nationwide Boiler’s Director of Sales. Nationwide Boiler was assisted in securing this project with the cooperation of their new Middle East representative, Aujan Industrial Solutions, as well as the EPC customer, Redland Industrial Services (Arabia) Ltd.

    The equipment will be utilized for a minimum of one-year during the commissioning of Saudi Aramco’s 106-square-kilometer refinery and terminal in Jizan, Saudi Arabia. The facility is expected to process more than 400,000 barrels-per-day of crude oil for domestic and international customers. It will be entirely self-sufficient, providing power to locally owned manufacturing and service companies. The boilers and associated equipment will load on a Ro-Ro style ship (roll on/roll off) at the port of Houston, with an expected transit time of six weeks before arrival at the Port of Jizan. Shipping of the equipment has commenced, but will be coordinated in a phased process.

    Founded in 1967, Nationwide Boiler Inc. provides industrial rental boilers, new firetube and watertube boilers, and quality used boilers to customers worldwide. The company specializes in low emissions and high efficiency equipment, including the CataStak™ SCR system and EconoStak economizers.

  • Fremont, CA, August 30, 2018

    Nationwide Boiler Inc., the industry’s leading supplier of CataStak™ SCR systems for ultra-low NOx emissions on package boilers, recently supplied the first-ever temporary selective catalytic reduction (SCR) systems utilizing a 32.5% liquid urea solution, commonly known as DEF (diesel exhaust fluid), as the reagent. Although the company has provided urea-based systems for stationary equipment for nearly eight years, this was an industry-first for a temporary rental application. Anhydrous ammonia, a chemical with stringent HAZMAT handling requirements, has been the standard reagent for rentals.

    “This is a big step in our industry,” stated Sean McMenamin, Nationwide Boiler’s Director of Environmental Solutions. “Until now, ammonia was the common reagent utilized for a temporary SCR application. We often found that the strict handling requirements associated with the use of ammonia would hinder our ability to provide an SCR on certain job sites. We have now built an inventory of urea skids and associated ductwork required for these rental systems. This allows us to provide a safe alternative for customers adverse to ammonia handling requirements.”

    The first rental project required two (2) trailer-mounted 99mbtuh saturated steam boilers, while the second project required six (6) trailer-mounted 99mbtuh superheated steam boilers. A ground-mounted CataStak™ SCR system, utilizing urea as the reagent, was supplied for each boiler. In total, Nationwide Boiler provided eight (8) urea-based CataStak SCR systems for the first time in the rental boiler industry, all of which achieved less than 5ppm vd @ 3% O2 NOx outlet levels.

    For over fifty years Nationwide Boiler has provided temporary and permanent boiler system solutions to industrial customers worldwide. The company specializes in ultra-low emissions and high-efficiency equipment, including the CataStak™ SCR system for as low as 2½ ppm NOx. Nationwide Boiler recently introduced the DataStak™ Emissions and Efficiency Monitoring System to provide customers with real-time data typically required for fired equipment applications. The company’s controls division in Washougal, WA, Pacific Combustion Engineering, designs and fabricates the control system supplied with both temporary and permanent SCR equipment.
