Brief Description of Main Solutions

   Instead of the two turbine plants of 6 MW capacity each, which have expired their service life, there have been installed two turbine plants of 30 MW capacity each including the backpressure steam turbine and the electric generator.

There has been fulfilled the turbine generator sets foundations reconstruction with the anti-vibration top plate having been installed.

There has been fulfilled the reconstruction of the electric engineering equipment of the power output and the auxiliary needs system.

There has been implemented the new PACS (Process Automatic Control System) for the newly installed steam-turbine generator sets together with the recovery boiler.

There has been fulfilled the required reconstruction of the engineering systems.
