The GTU-TPP's commissioning has increased the capabilities of Yelabuga power grid
3 January 2019In the Yelabuga city (Republic of Tatarstan), at the site of a local Heat Network Company, the new power plant was put into operation.
The modern power generating facility is created on the basis of gas turbine technologies. GTU-TPP has electrical capacity of about 20 MW and thermal capacity of 28 Gcal / h. The designer is Tatbelenergoproekt LLC. Construction was conducted by the holding company IED-holding (investor of Yelabuga Heat Network Company).
The main equipment of GTU-TPP consists of four gas turbine units Solar of type Taurus 60 GS with a unit capacity of 5.6 MW and four hot-water waste-heat boilers. The fuel for turbines is natural gas.
Thanks to effective technology, the cost price of produced heat will significantly decrease what will allow to restrain the growth of tariffs. Besides, the facility's commissioning has increased the capabilities of Yelabuga power grid and reliability of power supply to consumers.
In composition of power plant there is operates ENERGAS gas treatment system (GTS) which provides designed parameters of gas on purity, temperature, and pressure and flow rate. GTS comprises a gas treatment unit (packaged gas purification unit – PGPU) and a booster compressor station.
The main elements of the PGPU are a gas purification system consisting of three filtration lines and a drainage module, and a two-line gas metering unit. Additional equipment is a continuous chromatograph (calorimeter) and a dew point measurer with sampling devices.
In accordance with the project PGPU is performed the following functions:
- Gas purification from solid particles and droplet moisture to the turbine manufacturer's design requirements;
- Collection of trapped liquid in a drainage tank with subsequent transfer to a mobile vessel or special transport;
- Gas flow measurement;
- Determination and recording of gas composition and its changes;
- Determination of calorific value;
- Dew point measurement.
The capacity of the comprehensive gas treatment system is 8,240 m3 / h. All units are automated; local ACSs are integrated into the APCS of the thermal power plant. Equipment version – container; block-modules are equipped with safety and life support systems.
Step-by-step commissioning of this system has been carried out by the company ServicENERGAS which is part of ENERGAS Group. Technicians have performed erection supervision, start-up and adjustment works, individual testing, and operability verification of BCS and PGPU in conjunction with generating equipment of the GTU-TPP, as well as training of the operating personnel of customer.
