BCS of fuel gas for the combined cycle gas turbine unit of Minsk CHPP-2 successfully underwent factory tests before shipment
24 October 2020
In the course of testing of booster compressor station (BCS), the operability of compressor, process, measuring, analytical, and electrical equipment has been checked. The local ACS, oil system, valves actuation, integrity of cable lines, and leak-tightness of all assemblies and joints of the BCS were tested.
Preparation is underway for station delivery to the Minsk CHPP-2 operation site. The process unit is supplied with a high degree of prefabrication (98%) and a maximum integration of the components on a single frame what significantly reduces the duration of the mounting works and pre-start activities.
The launch of new screw type BCS will increase the capabilities of the existing gas treatment system consisting of three SJCM reciprocating units and modernize the gas supply scheme for turbines of the CCGT-65 combined cycle gas turbine unit.
The BCS capacity (16,400 m3 / h) is 100% of the maximum fuel consumption for two SGT-600 gas turbines, which guarantees complete backup of reciprocating compressors. BCS will provide stable design gas values in terms of delivery pressure (2.481…2.581 MPa) and temperature (up to +50°C).
Implementation of the project will increase the reliability of CCGT-65 fuel supply and ensure uninterrupted operation of the combined-cycle power generating units at all modes and under any climatic conditions. All the work on commissioning the BCS will be fulfilled by the specialists of ServicENERGAS (part of the ENERGAS Group).
