Process for starting a gas and steam turbine plant

摘要

The method involves supplying a waste heat of a working medium to a steam system for production of steam driven by a steam turbine (20). A gas turbine (2) is started before the steam turbine is started. The steam turbine is started during presence of the steam in the steam system and is stressed by the steam. The steam system is adjusted during starting process in such a manner that steam temperature rises with small gradients.
