Compressor station of fuel gas for the gas turbine unit of Tomsk CHPP-1 is brought to modern standards of operation

22 June 2020



The structure of Tomsk CHPP-1 of JSC Tomsk Generation 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) from 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 each CU varies in the range of 200 … 2,400 m3 / h.

At the operation site, the major repair and upgrade of CU No. 1 were performed:

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



Works were completed with own and integrated tests. CU No. 1 has operated in normal mode, without any complaints.

In 2019, a scope of similar activities was held here at compressor unit No. 2. Thus, for today the BCS of fuel gas is brought to modern standards for the production and operation of gas compressor equipment.

The project was carried out by specialists of the ServicENERGAS (part of ENERGAS Group). Its 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. In 2012-2013 PBS was reconstructed on investment program of the Tomsk branch of JSC TGC-11 (now JSC Tomsk Generation). 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 SDPP-2 allowed successfully compensate for the eliminated capacity of the Siberian nuclear power plant, the source of long-distance heat supply for Tomsk.
