The 225 MW coal-fired power unit is put into operation at the Cherepetskaya GRES. The main power unit equipment includes a turbine, a generator and a home-produced boiler unit. ENEX (OAO) performed adjustment of this power equipment.
The unique character of the given project involves utilization of advanced technologies. For example, during the construction of a boiler plant for the first time in 25 years a coal-based generating unit is used. Besides, ENEX’S engineers were among the first in Russia to use a desulfurization system. The realized air-assisted ash and slag removal system will help to minimize damage to the environment. The pulverized-coal system with mills is realized for the first time in Russia, it enables to safely burn such explosive fuel as Kuznetsk long-flaming coal. A high-pressure boiler (nominal capacity 630 t/h) was used in implementation of this project. It allows burning coal with minimum NOx emissions.
The power unit was built in order to enhance power supply reliability of consumers living in the Tula, Moscow, Kaluga, Orel, Smolensk, Bryansk and other neighbouring regions.
