Restoring the natural balance
JSC "DGC" more than 10 years implement projects aimed at reducing the negative impact on the environment
The greatest effect in terms of reducing emissions was provided by the gasification of power plants. With 2007 for 2017 inclusive, Nikolaevskaya CHPP, Khabarovsk CHP-2, 8 boilers of Khabarovsk CHP-1, power unit No. 4 of Khabarovsk CHP-3 were transferred to the blue fuel. The project started by the company in the Khabarovsk Territory more than 10 years ago allowed not only to increase the reliability of the equipment operation, but also to reduce emissions of harmful substances into the atmosphere by 3 times and 4 times - ash and slag waste output at power facilities operation.
Since 2007 up to now, emissions of harmful substances into the atmosphere from Khabarovsk CHPP-1 have decreased by more than 14 thousand tons per year. The output of ash and slag wastes decreased by 4 times: from 263 thousand tons to 85 thousand tons. In addition, gasification solves one of the most urgent issues - the limited resource of ash disposal of Khabarovsk CHP-1.
In the case of Khabarovsk CHPP-2, statistics are such that the plant's atmospheric emissions have decreased by 10 times. In 2007, harmful emissions were more than 2,5 thousand tons per year, and in 2016 this figure was 226 tons per year. Nikolaevskaya CHPP at the same time became more environmentally friendly at 5 times, reducing emissions from 3,4 thousand tons to 684 tons per year.
The gasification of the stations in the Khabarovsk Territory allowed for "ten years" to reduce emissions to the atmosphere by 122,8 thousand tons, the output of ash and slag wastes by 900 thousand tons.
In Primorye, where the transfer of equipment for gas was engaged from 2010 year, the main object for reconstruction was Vladivostokskaya CHPP-2. To date, 10 boiler plants have been gasified (4 is still operating on the coal). For 7 years of the project, the station reduced its emissions more than 10 times: from 49,3 thousand tons to 4 thousand tons per year. In 13 times the output of slag decreased: from 629 thousand tons to 48 thousand tons per year. In addition, 3 boiler plants - Vladivostok HPP-1, Boiler Room Severnaya and The Second River - were transferred to natural gas.
FROM ZOLA TO GREEN
An important part of the ecological program of the DGC is the reclamation of the ash dumps of the stations. The project allows the return of significant areas of former landfills for storage of slag and ash.
To date, in Vladivostok, almost 30 ha of the ash dump located in Gornostai Bay have been reclaimed. Another 50 ha was reclaimed at the ash dumps of Khabarovsk CHP-3.
While the energy sector is putting the territories in order, the city authorities are thinking how to use these spaces. Among the proposals - parks, stadiums, children's and youth sports school, new neighborhoods and more. Some experts believe that these territories can be returned to the city as green areas.
In addition, in the coming year, the energy sector will have a large amount of work to build up and build ash dumps necessary for the safe disposal of waste. This will include the construction and the construction of dams ash dumps at Primorskaya GRES, Artemovskaya CHP, Khabarovsk CHP-1, Birobidzhan CHP.
So, over the past years, work has been under way to reconstruct two "ash dumps" of Artemovskaya CHPP. In order to ensure the future needs of the CHP, a project for the reconstruction of the ash dump No. 1, which is currently completed, is being developed. The project will increase tieredness and in the coming years to resume the storage of ash and slag wastes.
One of the most significant projects is the construction of a new ash dump "Green Beam" of Partizanskaya GRES. This is a vital object, replaced by an old ash dump that has exhausted its capacity. It will ensure a confident and reliable operation of the power plant for the next 50 years. The "Green Beam" is a modern ash dump, in the design of which all requirements in the field of ecology are taken into account. So, for example, in the box and on the slopes of the "blade" a screen is placed from the geomembrane - a special coating that protects the soil from the penetration of harmful substances. And to exclude the dusting of ash, in addition to traditional methods of dust suppression, sprinkler systems are provided, each of which is designed for irrigation in a sector with a radius of up to 70 meters. The construction of the first section has already been completed, now the commissioning and test runs of the equipment of the whole complex are underway.
FOR THE PERSPECTIVE
The "environmental program" of the DGC continues and has a perspective. From recent examples - specialists of Khabarovskaya Generation transferred boiler No. 15 of Khabarovsk CHP-1 to gas. For the station, it became the eighth gasified boiler. According to experts, the reconstruction will allow 15% to reduce emissions of pollutants from the entire mass of emissions of Khabarovsk CHP-1. In 2018, the branch's energy sector will transfer the ninth and last modern boilers of this CHP to gas fuel, thus completing the gasification project for the station. Coal will only boilers of the first stage, built in the 1950-s and not subject to reconstruction.
Another significant project implemented by DGK today is the construction of a chemical and biological treatment and disinfection station for sewage for the Khabarovsk CHP plant-2. The project has already spent more than 12 million rubles from the planned 105 million rubles. The project will significantly reduce the negative impact of the station on the Amur River. Completion of work is planned for 2019 year.
