This paper reports an investigation of Computational Fluid Dynamics (CFD) on the influence of injection momentum rate of premixed air and fuel on the timeless Moderate or Intense Low oxygen Dilution (MILD) combustion in a recuperative furnace. Details of the furnace flow velocity, temperature, O(2), CO(2), and NO(2) concentrations are provided Results obtained suggest that the flue gas recirculation plays a vital role in establishing the premixed MILD combustion It is also revealed that there is a critical momentum rate of the fuel-air mixture below which MILD combustion does not occur Moreover, the momentum rate appears to have less significant influence on conventional global combustion than on MILD combustionhttp://gateway.webofknowledge...
