How to heat the east
Without the development of energy infrastructure, the economic growth of the Far East is impossible
Yakutsk and the entire central part of Yakutia, which are isolated from the unified national electric grid, are now powered by the Yakutskaya GRES, built more than 40 years ago, and the low-power Yakutskaya CHP. The city is developing, and by 2020, according to experts' forecasts, the electric load of the central energy region of the republic due to the development of new industries will increase by 70%. In this regard, great hopes are pinned on GRES-2 - it will help replace the outdated capacities of the existing Yakutskaya GRES and create a reserve of power supply to consumers. The structures will be located on two separate sites: the main one - on Mount Chochur-Muran near Yakutsk, and the secondary site - at the foot of the mountain. Completion of the construction of the 1st stage, which was laid in 2012, is scheduled for 2015.
According to official data, the electric power of the 1 line of the Yakutsk SDPP-2 will be 193 MW, the installed heat capacity is 469 Gcal / h. The total capacity of two station queues will be 338,6 MW, 569 Gcal / hour. According to Deputy Prime Minister of the Government of Yakutia Pavel Marynichov, the state district power station-2 will solve "issues of reliability of power supply of the city".
“I mean not only the electrical load, but also the output of thermal power. The existing GRES is a station that has already seriously developed its resource, and, of course, a new energy source is something that is very, very necessary for the city and the central energy district, ”he said.
P.Marinychev explained that the GRES-2 will give prospects for further development of the republic's economy, because any new production necessarily needs electric energy. As an example, he led a transport and logistics center in the village of Nizhny Bestyah.
Another set of expectations from the new station is the improvement of ecology in the city. “I would like to especially note - look at the children standing above Yakutsk!”, - S. Tolstoguzov, General Director of JSC RAO Energy Systems of the East, pointed towards the city buildings. He promised that when the GRES-2 was built, some of the city's boiler houses operating on liquid fuel would be decommissioned and the city would “breathe” much easier. The Yakut GRES-2 will operate on natural gas from the Srednevilyuisky gas-condensate field. The use of highly efficient equipment will reduce the amount of harmful emissions into the atmosphere, exerting minimal impact on the environment.
"This construction is provided by the sources of financing, the object is to be handed over in 2015 year. In fact, there is no doubt. Probably, we do not, and builders do not, "commented G.Danchikov.
The construction of GRES-2 will create additional jobs in the city. The state will be formed mainly at the expense of local personnel. “We are not saying that we will bring specialists from other regions here,” said S. Tolstoguz. - Our employees are being released at the Yakutskaya TPP. We have a good school of Yakut power engineers. Basically, they (jobs - Prim.red.) Will be formed at the expense of local staff. "
As explained by the director of Blagoveshchensk CHP, Andrei Sazanov, the heat deficit in the city is 20%. "The operating CHP serves 80% of consumers in Blagoveshchensk," he said.
There is no talk about connecting new residential areas. “We mainly connect social facilities - schools, kindergartens, housing for floods,” continued A.Sazanov. According to him, with the commissioning at the end of 2015 of the 2 phase of the Blagoveshchensk CHP, commercial neighborhoods will be connected - “Severny”, “Ignatievskaya manor” - a promising housing under construction for young families.
The 2 stage of the Blagoveshchensk CHP is the expansion of the capacity of the existing station. An important feature of the construction site is that it is promised to embed new equipment into an existing building in a crucial production process without stopping it.
After the completion of the construction of the 2nd stage of the Blagoveshchenskaya CHPP, the staffing table will increase by 72 people. Only local personnel will be involved in the work. After the modernization, the electric capacity of the heat and power facility will increase by 120 MW and will amount to 400 MW. Thermal power will increase by 188 Gcal / h, reaching 1005 Gcal / h. Annual heat production will reach 464 million kW / h, and electricity supply - 427 million kW / h. The main fuel for generating heat and electricity at the CHPP will be coal from the Yerkovetsky Amur deposit.
To reduce emissions of harmful substances, a number of engineering and technological solutions are provided - high-tech, step-by-step burning of fuel and re-use of gases. The exhaust pipes will be equipped with sound attenuators.
The ash in the flue gases will be captured according to the standard scheme - in the electrostatic precipitators an electric field is created that attracts solid particles. At the same time, 98,6% of ash particles are trapped. Heavier wastes - slag - will be transported through the pneumatic duct to the channel of hydro-ash removal and pumped to the ash dump for storage. In the long term, these wastes can be used in construction, for example, for the production of various concretes.
If the pace of development of the city remains the same, then through 4-5 years, CHP will again exhaust its resource. Therefore, the leadership of the CHP and the region is already thinking about alternative fuels, which, quite possibly, will be gas.
Vostochnaya TPP is a new facility for heat and power generation, being built in Vladivostok by RusHydro. Although the scale of the power facility being built on the site of the existing boiler house is inferior to projects in Blagoveshchensk and Yakutsk, today it is a key project of RAO ES of the East in the south of Primorsky Krai.
Last week, the first gas turbine unit (GTU) was installed at the Vostochnaya CHP plant in Vladivostok. In total, such installations with the capacity of 46,5 MW will be three.
"Today, here we put the first turbine on the base, all this is done on the basis of the old boiler house 1960-ies. The complexity of the project is that we must combine new construction with existing equipment, "continued E.Dod. He stressed that "the facility is extremely important for residents. Its construction will not lead to an increase in the tariff, but will improve the ecological situation and the noise load. "
The new power plant will become a high-tech and environmentally friendly energy facility. The equipment will meet the most modern samples for generating sources. The use of gas as the main fuel will help reduce the emission of harmful substances at the new station in 3-4 times below the maximum permissible concentrations.
“This is a major step towards the development of the entire Far East. The region cannot develop without energy, therefore we, along with RusHydro, create conditions for business development in the Far East, ”said the Deputy Chairman of the Government of the Russian Federation, the Plenipotentiary of the President in the Far Eastern Federal District, Yury Trutnev
The general director of the holding "RAO ES of the East" S. Tolstoguzov noted that it is planned to "build two more such large power plants that will be able to take over and distribute the heat load of the city."
Start the station in the work planned in 2015 year. Thus, Vladivostok will meet the heating season next year with the Vostochnaya CHPP.
