This work presents an analysis of the dynamic behaviour of a HRSG (heat recovery steam generator) during start‐up. A calculation program based on a quasi‐steady method is constructed. A typical high‐pressure HRSG is designed conceptually and analysis is performed to examine the influence of the gas inlet condition of the HRSG on its start‐up behaviour. Effects of the gas turbine operation mode and the gas bypass are analysed. In addition, the water level control during start‐up, which is one of the most important facts in the real plant operation, is simulated. Through a parametric calculation, the effect of the control parameters on the start‐up behaviour is analysed and examples of optimum control are demonstrated. Copyright © 2000 John Wiley & Sons, Ltd.
