A thermal-hydraulic analysis program that can be applied to the complex flow network consisting of tubes and headers in the furnace water wall of fired boilers has been developed. This program can evaluate the flow distribution in the tubes at both steady and transient states. Heat flux distribution in the furnace, which determines each tube's heat absorption, is given by the threedimensional combustion analysis. By using this program, detailed information about the water flowing in the tube, such as temperature, quality, mass flux, etc. is obtained and the temperature of the furnace water wall is calculated. This program is applicable to most operating conditions including slagging, soot blowing and water filling at boiler start up. Both steady and transient states analyses show satisfactory agreement with measured values. This program has already been used to design fired boilers, and good performance has been obtained.
