CONTROL ARRANGEMENT FOR STEAM SUPPLY AND METHOD OF SUPPLYING OVERLOAD STEAM INTO A STEAM TURBINE

摘要

The invention relates to a control arrangement (1) for supplying steam of a steam turbine (11) with a main flow path (2) for steam. The main flow path (2) has a flow cross-section (12) which can be adjusted by at least one control valve (4). A secondary flow path (3) can be connected in a fluidic manner via the control valve (4) to the main flow path (2). The invention also relates to a method for introducing overload steam into a steam turbine (11), in which in a control valve (4) part of the fresh steam flow (19) is diverted and is supplied to a turbine stage (18) downstream of a control stage (18a).
