Reconstruction of the CPS of Blocks 1 to 4 of the Maritsa East 2 TPP
Under our contract with the Maritsa East 2 TPP for conformity assessment of the investment project, construction supervision and engineering pursuant to the FIDIC conditions for design projects, construction, procurement and commissioning (The Yellow Book) of the Reconstruction of the CPS of Blocks 1 to 4 of the Maritsa East 2 TPP project, in conjunction with our duties, we performed the following:
The Maritsa East 2 TPP is the largest Thermal Power Plant in Bulgaria. It is one of the three Power Plants in the Maritsa East Complex which is situated in the south west part of the country. The Plant is located 280 km away from Sofia, and 60 km away from Stara Zagora. It is built on an area of 512 ha in land of Radetski village. East of it is the Ovtscharitsca Dam. The TPP 2 has a total installed output capacity of 1465 MW, and it comprises eight Units, each complete with a desulphurisation equipment. The TPP works with local lignite coal mined in the Maritsa East's mines.
The Agreement for Reconstruction of the Cooling Pump Station (CPS)at Units 1 to 4 of the Maritsa East 2 TPP, was a contract for engineering, equipment supply, construction and commissioning (EPC), at a fixed contract price, under the FIDIC requirements (The Yellow Book). The Project was funded by the Kozloduy EBRD fund.
Technical water feeding to Units 1 to 4 of the Maritsa East 2 TPP is ensured by CPS 1 which is in operation since 1966. The pump station is located on the shore of the Ovtscharitsca Dam and has six axial pumps installed. Each pump is with a capacity of 19,800 m3/h and pressure of 10.3 water column. The six cooling pumps feed water Units 1 to 4.
Тhe cooling pumps were replaced by pumps with better efficiency and greater performance. The cooling pumps are vertical, axial, manufactured by FlowServe, Spain. The pump replacement is related to a reconstruction of the suction chambers, the systems for cleaning the water from mechanical impurities, as well as the pressure pipelines up to their connection to the pressure cooling collectors. Along with that, a new SCADA/DCS system was implemented.
