Abstract (en)
[origin: EP2592241A1] The method involves increasing injectivity of a steam turbine and lowering pressure in a waste heat steam generator to utilize storage reserves in the waste heat steam generator to increase steam generation such that heat energy is quickly supplied to the waste heat steam generator. A power characteristic of a gas and steam turbine system due to increasing of the injectivity of the steam turbine and decreasing of the pressure in the waste heat steam generator is made greater or equal to existing or present power of a stationary operation.
