ServicENERGAS and Tomsk generation have extended a long-term contract for maintenance of fuel gas BCS for GTU of Tomsk CHPP-1

30 January 2019

The structure of Tomsk CHPP-1 comprises gas-turbine power generating unit GTU-16 operating on a cogeneration cycle. Its electrical capacity is 14.7 MW, thermal – 19.5 Gcal / h.

The main equipment of GTU-16 is waste-heat boiler manufactured by the ZiO (Podolsk) and gas turbine unit of type TBM-T130 produced by the Turbomach. This unit is based on turbine of industrial type Titan 130 (Solar Turbines Inc.).

The main fuel for power generating unit is natural gas. The compression and feeding fuel gas to the turbine under required operating pressure of 2.8 MPa are performed by the booster compressor station (BCS), which was supplied by the company ENERGAS.

BCS is composed of two compressor units (CU) of screw type. Block-modular CUs are placed in weatherproof enclosures; they are equipped with life support systems and safety systems. Capacity (gas flow) of CU varies in the range of 200 … 2,400 m3 / h.

In the course of compressor units operation, specialists of LLC ServicENERGAS (part of ENERGAS Group) perform their comprehensive maintenance. In addition, ServicENERGAS supplies a complete set of consumables.

Works are carried out according to the agreed schedule within the framework of long-term service contract with JSC Tomsk generation (formerly Tomsk branch of JSC TGC-11). Currently, this agreement is extended until the end of 2021.

From the date of BCS start, the operating time of units has ranged about 10,000 hours. In early January, the engineers of ServicENERGAS completed the project to upgrade and bring the BCS to modern standards for the production and operation of gas compressor equipment:

- A new screw oil-filled compressors are installed – the main elements of the units;
- Two-tier capacity control systems of CU are improved;
- Maintenance and upgrade of the compressor units’ oil systems were performed;
- Software is updated;
- There were added new set points and protections.

Project implementation has increased fuel gas quality, gas feeding reliability and, as a result, GTU-16 operation efficiency.

REFERENCE. Previously, CHPP-1 was named as Tomsk peak-load boiler station (PBS). In 2012-2013 PBS was reconstructed on investment program of the Tomsk branch of JSC TGC-11. Within frames of project at the PBS there was built new generating facility.

The solemn ceremony of GTU-16 commissioning took place on February 20, 2013. PBS reconstruction has raised issuance thermal power what allowed to transfer boiler station from peak mode to the basic mode of operation. Introduced electric capacity of PBS has increased the capabilities of the Tomsk power grid.

Upon completion of the project, the PBS received the status of a thermal power plant and the name of CHPP-1 – in honor of the first power plant built beyond the Urals back in 1896.

Creation of gas turbine unit was implemented by the JSC Rosengineering. Upgrade of the PBS along with the launch of a new turbine unit at the Tomsk SDPS-2 allowed successfully compensate for the eliminated capacity of the Siberian nuclear power plant, the source of long-distance heat supply for Tomsk.
