The subject of this tender for tendering unit (VE) 3.4 is planning and construction work for the installation and commissioning of two steam turbine sets, consisting of a backpressure steam turbine and a condensation steam turbine with associated generators and transmissions, including their ancillary systems.

The backpressure steam turbine is dimensioned for the steam volume of a combustion and steam generator plant for low-calorie fuels, and the condensation steam turbine is dimensioned to the steam volume of a combustion and steam generator plant for high-calorie substitute fuels.

Two independent steam turbine sets are to be built.

The steam turbine sets are supplied with live steam (40 bar (a), 400° C. at the turbine inlet) via the water/steam circuit VE 3.6. The amount of live steam corresponds to the steam production of the respectively assigned steam generator. Steam (3.4 bar (a)) can be extracted from the steam turbines for use in process technology via regulated withdrawals. The exhaust steam from the condensation steam turbine (0.1 bar (a)) is taken over by VE 3.5 all year round and condensed in the vacuum air condenser.

The exhaust steam from the backpressure steam turbine (1.2 bar (a)) is taken over by VE 3.5 and, depending on

Condensed operating procedure for thermal use in a backpressure heating condenser or for heat dissipation in the backpressure air condenser.

A recooling circuit is available via VE 3.6 for cooling the steam turbine sets. The

Steam turbine sets are located within the turbine hall on the turbine level, set up on

base frame. A turbine tower crane is arranged below the turbine hall ceiling for the maintenance and repair of the steam turbine sets.
