✦ Synopsis
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 in#uence of the gas inlet condition of the HRSG on its start-up behaviour. E!ects 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 e!ect of the control parameters on the start-up behaviour is analysed and examples of optimum control are demonstrated.
