ABSTRACT

Numerical simulations are performed on complex flows in an industrial boiler. Three-dimensional steady compressible continuity and Navier-Stokes equations are solved along with energy and species equations, with k-ε turbulence model. The separate supply of hydrocarbon fuel and air into a boiler is modeled using two concentric tube flows with swirling velocity of air. The gas radiation heat transfer is considered. Calculations are carried out via a commercial finite-volume code of FLUENT, on a CRAY YMP-4E/464. Numerical results are examined for the dependence of furnace exit gas temperature (FEGT). Emphasis is placed more on actual design implications rather than on numerical procedures, especially FEGT for the design of the heat exchanger at the exit of boiler.
