GE to Optimize Croatia’s Sole Coal Plant

By Editors of Power Engineering

GE’s Power Services announced it will modernize Hrvatska Elektroprivreda d.d.’s power plant in Plomin, Croatia, which is the only coal-fired power plant in the country.

GE’s retrofits—the first of this kind executed in the country—will help improve the plant’s heat rate, increase its power output, lower its operational and maintenance costs and extend the operating life of the steam turbine.

The retrofit service is part of GE's new Fleet360 platform of total plant solutions to service GE and cross-fleet components for utility and industrial plant operators worldwide. GE will upgrade a D2Y252 A steam turbine with 3D blades. After the retrofit of the 210-megawatt steam turbines, the plant’s output should increase, and the efficiency should be improved by up to 3.6 percent by reducing specific heat consumption.

The power plant upgrade will include a major overhaul of the high-pressure and intermediate-pressure parts of the steam turbines with a replacement of capital parts. The retrofit of the low-pressure part of the steam turbine will also feature the use of GE’s 3D blades, a new rotor, blade carriers, an inner casing and other spare parts. Additionally, the lifetime of the steam turbines will be extended for an approximate additional 200,000 operating hours.

The steam turbine retrofit is expected to start in May 2017, with the rest of the upgraded equipment scheduled for July 2017.
