The 250MW turbines of modern double body concept designed for higher input steam parameters replaced the original steam turbines of 2x210MW of foreign make. The concept of turbines also allows steam offtake for industrial heating purposes, in this case for a heat supply to Chomutov, Jirkov and Klasterec nad Ohri. Thanks to its efficiency which is well reflected in a drop of specific fuel consumption, they also contributed to reduction of environmental load of the power plant for the entire region. According to the power plant operator, ČEZ a.s., improvement of emission parameters reaches 60% on average.
“Successful implementation of this project is an important piece of reference that will help our company strengthen its position in world markets”, says project manager Daniel Doubrava.
The Prunéřov power plants are the largest coal-fired power station in the Czech Republic, and the upgraded power plant Prunéřov II is thus the youngest coal-fired power plant operated by ČEZ. Prunéřov I power plant with Škoda steam turbines of 6 x 110MW was put into operation between 1967 and 1968. At the beginning of 1990s, its four blocks underwent extensive renovations carried out again by Doosan Škoda Power.
