Overview

Computational fluid dynamics analysis uncovers how hydrogen blending and equivalence ratio impact NOx emissions in industrial boilers.

Key Points

  • Increasing hydrogen content elevates flame temperature and NOx emissions, while reducing CO and hydrocarbons.
  • Simulations reveal that an equivalence ratio of 0.8 balances efficiency with emission control, impacting performance.
  • Assessment using computational fluid dynamics showed unique staged-combustion mitigates NOx by 15-20% compared to single designs.
  • Findings suggest optimizing parameters like hydrogen fraction is crucial for efficient combustion in boiler systems.
