Techno-Environmental Analyses and Optimization of a Utility Boiler Based on Real Data

A numerical simulation for analysis and optimization of the performance NOx production was applied to a natural gas fuel boiler in South Pars Gas Complex. For this purpose, nine actual environmental operational parameters were measured recorded every two hours then averaged daily year. Using thermodynamic laws, important such as body exhaust flue losses, well thermal efficiency exergy efficiencies combustor boiler, calculated each day. The results show that, owing changes conditions, varied from 83% 87% 27% 32%, respectively, during In addition, by optimizing excess air percentage, could be increased 1.5% 3%, most days
