Nationwide Boiler recently completed boiler installation projects for two California food producers, with both systems undergoing formal compliance source testing for regional emissions standards.
The first project involved installing a 300 HP, 150 psig Hurst firetube boiler equipped with an Oilon ultra-low NOx burner. As part of the installation, Nationwide Boiler supplied a new feedwater system and blowdown separator to increase facility steam capacity. Source testing recorded average NOx emissions of 3.1 ppm and less than 2 ppm CO output (corrected to 3% O2). The system achieved a 3:1 turndown ratio, with modifications underway to reach 4:1.
The second project utilized an in-stock 180,000 lb/hr Babcock & Wilcox (B&W) package watertube boiler paired with a CataStak™ Selective Catalytic Reduction (SCR) system. Following commissioning, source test results at the food facility indicated average emissions of less than 1.5 ppm NOx, sub-1 ppm CO, and sub-3 ppm ammonia slip (corrected to 3% O2). These output levels meet the San Joaquin Valley Air Pollution Control District’s upcoming 2029 requirements. According to Nationwide Boiler, the CataStak system has been installed in more than 250 applications globally.
“These projects highlight our ability to deliver both custom-engineered systems and expedited, in-stock equipment that meet today’s most stringent performance and emissions requirements,” said Jim Lieskovan, Vice President of Sales at Nationwide Boiler. “With solutions like our CataStak SCR and Oilon’s ultra-low NOx burners, we support California’s food industry and customers across the globe with systems that ensure compliance with today’s standards.”
The installations come as industrial facilities in California and other regions across the U.S. navigate increasingly strict state and local air quality regulations for manufacturing equipment.
