T1 Simulation of Turbulent Combustion and Heat Transfer in High Temperature Furnaces JF International Journal of Fluid Mechanics Research JO FMR YR 1998 FD 1998-06-01 VO 25 IS 1-3 SP 255 OP 265 AB A complete simulation model of the combustion chamber of high temperature gas fired furnaces has been developed. It describes the turbulent flow, combustion, heat transfer and NO formation in the flame. For the radiant heat transfer spectral effects have been included. It could be shown that increasing the roof refractory emissivity from 0.4 to 1 increases the energy efficiency with 2 to 5%. The effect of local turbulent fluctuations on radiative fluxes has been found to be important only in the initial part of the flame, fluxes increased by about 27% maximum. NO formation strongly depends on gas-air mixing. Model results could be compared with existing semi-technical scale experimental data.
