Highly efficient combined-cycle power generating unit CCGT-225 has been operating since October 2012. The designed electric capacity of the CCGT is 225 MW (actual 227.4 MW); the thermal capacity is 110 Gcal / h. The basis of power unit consists of two PG6111FA gas turbine units produced by GE, SST PAC 600 steam-turbine unit of Siemens, and two waste-heat boilers.

Fuel feeding to the PG6111FA turbines is carried out by ENERGAS system which comprises gas treatment station and gas booster station consisting of three compressor units (CU). The specialists of the ServicENERGAS Company (part of ENERGAS Group) carry out overhaul of CU-1 and CU-3.



The set of work comprises the following activities:

1. Installation of new screw oil-filled compressors – the main elements of the CU.

2. Local repair and restoration works.

3. Replacement of consumables including gas filters of 1st and 2nd purification stages and oil filters.

4. Oil replacement. The CU oil system will use ester synthetic oil of the new generation ESTSYN CE, which is specially created for units made based on screw compressors.

5. Pressure testing – checking all assemblies and connections for tightness.

6. Start-up and adjustment works.

7. Range of individual and integrated testing of repaired equipment.



REFERENCE:

Syzran CHPP of the Samara branch of T Plus provides electricity and heat supply to industrial consumers and population of Syzran city and Syzran District. The commissioning of new capacities in 2012 made it possible to supply heat to the Central District of Syzran that improved the city's ecology by decommissioning more than 50 small inefficient boiler houses. CCGT-225 is one of the most efficient and technologically advanced facilities of a new generating in the Middle Volga.
