The combustion zone in a process heater can be treated as an agglomeration or series of confined jet-flame systems that emanate from burner tiles and expand to an allocated fire box crosssectional area. Possible failure of the tubes containing the process fluid due to local over heating requires the ability to predict detailed radiative heat flux and temperature distribution from the knowledge of the inlet and boundary condition and the system geometry. An analytical model has been developed which is capable of determining the heat transferred by radiation. The variation of the dimensionless heat flux number with varying firebox to burner area ration, length to clearance ratio and a dimensionless distance along the combustion zone is studied. A C-program is developed which displays these results for various single-side-gas-fired tubes in floor-fired box furnace geometry. Results were also displayed for the variation of heat flux along the length of the vertical tube carrying the process fluid for single side fired tubes in a two-burner floor-fired box. The results of the analytical model developed are in good agreement with the published data.
