Ammonia co-firing is one of the few decarbonization routes that reuses a pulverized-coal boiler already in service rather than replacing it. However, changing the fuel of a burner in operation involves three conflicting constraints.
Inefficient combustion: uneven fuel distribution increases energy consumption and operating cost. Emissions: improper NH₃ co-firing generates additional NOx, cancelling the environmental benefit the project aims for. Safety: flashback and blowout threaten continuous operation of the unit.
All three emerge only once the burner is installed and firing, while trials on real equipment are slow and risky; the problem therefore has to be solved by simulation first.
The deliverable is a criteria set plus a tool that sweeps options: the second and the tenth question about a different burner configuration are answered within the same framework. A plant weighing a decarbonization roadmap thus gains a long-term evaluation capability.
Send the boiler and existing burner data — CFDWAYS will advise what simulation can establish about co-firing ratio, injection configuration and the effect on NOx before any intervention on the equipment.
