Oil-fired boilers play important roles in chemical industry and power plant, the main purpose is to provide heat energy. Fuel burning, the heat transfer for flue gas to boiler, pressure in boiler and control of fuel flow rate will influence stability of operation and may cause pressure over the allowable range. Therefore, simulating real boiler by computer program can help engineers more familiar with boiler, and decrease the frequency of accident consequentially. This research developed a dynamic simulation program of natural circulation water-tube boiler. Developing program with solving the mass balance, energy balance, heat balance of firing, arranging the thermodynamic property of saturated state, and then construct them into a series of subroutine models. Visual Basic 2005 was used to develop the program. The pressure controller was used to control fuel flow rate. From the result, the program can simulate the response of boiler output variables under disturbances.
