As industries worldwide look for sustainable energy solutions, Hydrogen (H2) is emerging as a promising alternative to traditional fossil fuels. At John Zink, we’re leading the charge in innovating combustion technologies that meet the evolving needs of our clients. One area of focus is converting tangentially fired boilers from natural gas to hydrogen. This process offers exciting possibilities but comes with its own set of challenges.

As leaders and organizations strive to reduce carbon emissions, the use of hydrogen as a fuel source continues to surface as a compelling alternative. Process heating through hydrogen combustion isn’t necessarily novel. The refining and petrochemical industries have leveraged the heating content in byproducts (many of those rich in hydrogen) to maximize unit efficiency, reduce the consumption of purchased fuel, and eliminate the release of unburned hydrocarbons to the atmosphere. While the carbon free nature to hydrogen offers a seemingly simple path to carbon free emissions, transitioning to hydrogen presents several challenges that, if unmitigated, will negatively impact the viability of products and services critical to our daily lives.

John Zink executed a successful conversion for Puerto Rico Electric Power Authority (PREPA), transforming two 410 MWe tangentially fired boilers at the South Coast Generating Station. The conversion involved equipping unit #5 and #6 boilers with advanced gas burners, safety valves, and pressure-regulating skids. This allowed PREPA to flexibly switch between natural gas and fuel oil firing, achieving fuel cost reduction and adherence to regulations. The conversion preserved existing oil-firing capabilities and optimized boiler performance, resulting in substantial operational benefits for PREPA.

We assisted a major oil refinery in reducing NOx emissions on three 550,000 lb/hr tangentially fired boilers while considering retrofit cost, timeline, and equipment compatibility. The retrofit successfully achieved target emissions, received an award for exceptional performance, and showcased our expertise in optimizing industrial combustion systems.
