The Kohtla-Järve Power Plant (Estonian: Kohtla-Järve soojuselektrijaam) is an oil shale-fired power plant in Kohtla-Järve, Estonia, about 15 km to north-west of the Ahtme Power Plant. It is owned by VKG Soojus, a subsidiary of Viru Keemia Grupp. It consists of Põhja Power Plant and Lõuna Power Plant (stopped operations in 2009).[1]
The Kohtla-Järve Power Plant (Põhja Power Plant) was commissioned in 1949–1967 with designed electrical capacity 48 MW.[2] The first generator of the plant was commissioned in January 1949. This was the first time when the oil shale pulverized-firing combustion technology was implemented for power generation.[3] The first generator had a capacity of 12 MW.[4] At the beginning the plant used Riley Stoker boilers and General Electric generators; however, boilers developed for the pulverized firing of coal and lignite were not fit to work on pulverized oil shale.[4][5]
As of 2005, the power plant had capacity of 39 MW electricity and 534 MW of heat.[6][7] It is equipped by five stream generators and two hot water boilers (Barnaul BKZ-75-39F middle-pressure boilers). Its four turbines are manufactured by Fraser and Chalmers, Kirov Plant, Lang-Ganz, and Bryansk Turbine Works.[8]
In addition, an oil shale gas-fired plant was built next to existing plant. This plant is equipped with Energomash manufactured boilers and Kaluga Turbine Works manufactured turbines.[9]
