Reftinskaya GRES
Reftinskiy town, which is home to 18,000 people, is situated 2.5 km from the GRES, which produces 20,000 million KWh annually.
Reftinskaya GRES uses coal supplied from Ekibastuz that has calorific power of 3800–4100 cal/kg, ash content for moisture-free fuel of 40–43% and humidity of 6–9%.
On 3d July, 1963 the group of the formers landed in the suburbs of Asbest and, getting through the taiga jungle, went to research the ground for the building of electric power station that ought to become the leader of the ural energy providers.
The collective of the institute has been developing from the implementation of the electrification plan and projected all electro stations of the Great Ural, accumulated big experience.
After the series of control and testing of boiler and turbine, the first unit was plugged in on 24 December 1970.and immediately started to work fully operational.
And on 22 December 1980 in the occasion of the GRES building termination and achievement of the final planned production capacity of 3800 MW, the mass meeting took place, where the first secretary of the Sverdlovsk regional committee C.P.S.U.
So the conception of reconstruction and development of automated control system of country electric power stations, which was cultivated in Sverdlovenergo, started to be realized.
Fundamentally new, unprecedented on coal-dust units technology made work place of machinist more comfortable (panels were replaced by 8 monitors) and supplied personnel with the great quantity of information.
The plan of fuel supply includes car dumper, belt conveyor system, which are situated in underground galleries and aerial flyovers, units of pouring, crushing case.
As a result of cooperative work between scientists of UrS RAS's botanical garden, Institute of plants and animals ecology, Sykholozhskii forestry and powermen of Reftinskaya GRES on recultivation (i.e. reproduction of natural resources) of ash dump on the place, where waste was thrown down, pines of 3 metres grow.
[8] September 29, 2015 – Enel Russia has today inaugurated the Dry Ash Removal System at Reftinskaya GRES one of its most significant environmental projects – and the only one of its kind in the Russian power generation sector.
For the first time in Russia, the traditional hydraulic treatment of the ash produced by a coal plant as a waste material, has been replaced by the new, dry method of transportation and storage.
This new method will allow increase industrial use of ash: as long as it remains dry, it can be used in road construction, building materials, agriculture etc.
DARS potentially allows the shipping to clients of all of the ash produced by the power plant, namely up to five million tonnes per year.
The DARS project of Reftinskaya GRES was carried out within the framework of the Environmental Agreement that was signed by Enel Russia and the Government of the Sverdlovsk Region at the INNOPROM industrial exhibition in 2011.
[9] Earlier in 2015 Enel Russia announced the completion of the 99.9%-efficient fabric filters at three out of ten power units of Reftinskaya GRES, which are also part of the Environmental Agreement.
The fish protection device mode of operation is based on creation of a water-and-air screen in front of deep water intakes of the power plant.
On May, 13 Enel Russia inaugurated the modernized 500 MW Unit 7 at the Reftinskaya GRES coal-fired plant after a large-scale environmental retrofitting.
[11] On July, 11 within the framework of «INNOPROM-2015» International Industry Trade Fair Enel Russia announced that two more power units – No.
At each of the retrofitted 300 MW power units 14,600 ash-catching bags that achieve the best filtration of the flue gases have been installed replacing the obsolete electrostatic precipitators, which implied dismantling of roughly 3,000 tons of metal works.
At Unit 5, the modernization works included installation of low-emission burners, which would allow to significantly reduce NOx emissions.
[12] Late in 2017 power unit No.1 of Reftinskaya GRES was equipped with a new gas treatment system which helps the modern electrostatic precipitators prevent emission of 13k ton of ashes/ year into the atmosphere.
In order to ensure the optimal exhaust gas treatment, the modern Russian electrostatic precipitators were installed which have high-frequency power devices and a new control system.
It allows increasing the efficiency of ash particle trapping, online controlling of voltage and electrode purge frequency, thus ensuring the equipment reliability.
