Case Study: a large U.S. chemical production company achieves EPA compliance with Day & Zimmermann boiler conversion services

Large U.S. Chemical Production Plant Chooses D&Z to Convert Industrial Boilers

A large U.S. chemical production company needed to convert its coal-fired industrial boilers to meet EPA guidelines under a very tight schedule, while maintaining operations at its North American sites. The company turned to Day & Zimmermann for engineering, procurement, and construction support, leveraging a long-standing 30-year relationship.

Day & Zimmermann converted two existing 220,000 lbs/hr, 900 psi superheated coal-fired industrial boilers to operate on natural gas and No. 2 fuel oil, and installed new air quality control equipment including an SCR, economizer, and ammonia injection grid. By planning carefully and coordinating with equipment vendors, Day & Zimmermann safely shaved four days off the schedule, delivered significant cost savings, and completed the work with zero OSHA or human performance issues, leading to similar projects at four other U.S. locations.
