Résumé

The present work is a simplified calculation procedure of heat transfer in oil-fired flame tubes. The relations for the distribution of heat liberation and soot concentration along the tube and which are needed in the calculations were based on experimental data obtained on a horizontal, segmented, water-cooled flame tube, under operating conditions close to those occurring in actual cases. The zonal method is applied in calculation of heat by radiation. The main feature of the present calculation procedure is that it takes into consideration the non-uniformity of gas and radiation properties especially the absorption coefficient which is calculated based on the variation of soot concentration and partial pressure of the radiating gases along the flame tube. The comparison between the results of this simplified procedure and the experimental data showed the validity of this procedure in predicting the heat transfer along flame tubes.
