Combustion Engineering — Stoichiometry, Thermochemistry & Emissions
Thermodynamics
PhD-level combustion science: stoichiometric and non-stoichiometric fuel-air ratios, Orsat and NDIR flue-gas analysis, first-law adiabatic flame temperature calculation using sensible enthalpy integration, chemical equilibrium at high temperature, and extended Zeldovich NOx kinetics with implications for burner design and emissions compliance.
Learning Objectives
- Write and balance complete and incomplete combustion reactions for hydrocarbon and oxygenated fuels
- Compute stoichiometric air-fuel ratio (AFR), equivalence ratio φ, and excess air percentage λ for any fuel
- Calculate adiabatic flame temperature for premixed flames by equating reactant and product enthalpies
- Apply the extended Zeldovich mechanism to estimate thermal NOx formation rate and its exponential dependence on T_ad
- Design flue-gas recirculation (FGR) strategies and low-NOx burner configurations based on kinetic principles
