Combined cycle installation and method for starting up a combined cycle installation

摘要

The method involves pausing the operation of a steam turbine system (2), and using the residual heat of a waste-heat recovery steam generator (16) and the heat originating from the turbine system before pausing the operation of turbine system. The residual heat and the heat generated before pause operation of the turbine system is used prior to a supply of thermal energy from an internal combustion engine (4) to the steam generator for generating steam, which is used to start up a steam turbine (6).
