Week 4

Boiler Operation, Combustion, Fuels and Emissions Control & Water Treatment, Corrosion Control and Environmental Protection

  • Explain NOx formation pathways - thermal, fuel-bound and prompt - and match low-NOx burners, overfire air, flue-gas recirculation and selective catalytic reduction to the pathway each addresses.
