This study investigates the impact of the design of a heat recovery steam generator (HRSG) on its dynamic behaviour under the boundary condition of a gas turbine start-up. For that purpose, a validated HRSG model with three pressure stages and reheater section is modified by replacing the...

The share of renewable energies in electricity and heat supply besides the conventional energy resources gains more importance. Accordingly, the efficiency and flexibility of modern thermal power plants should be further improved. To design such a system, it is necessary to generate detailed...

In this study, an entire simulation model is developed to investigate the influence of fast gas turbine start-up (within 20 min) on the dynamic behavior of a Benson heat recovery steam generator. The model includes a new high pressure feedwater control concept that considers a large number of...
