At the 2-th stage of Blagoveshchenskaya CHP, installation of the main equipment
The main power equipment began to arrive at the construction site of Blagoveshchenskaya CHPP (the customer-developer of the second stage of the facility of the same name, subsidiaries and dependent companies of JSC RusHydro, which is in the trust management of RAO Energy Systems of the East). To date, the following have been received: a deaerator, a steam turbine condenser, an economizer; on the way there are supports for the metal structures of the cooling tower and the screen surfaces of the boiler unit.
The beginning of the installation of the main equipment on the site marks the transition of construction to the decisive phase. The second stage of Blagoveschenskaya CHPP is the first of four thermal projects of RusHydro in the Far East, where it was possible to start these works. Part of the equipment is already installed in the main building of the station. In particular, a deaerator is installed, which is responsible for removing oxygen from the feed water to reduce corrosion of the equipment, the lifting operation took about 30 hours. Equipment weighing 20 tons with special equipment was lifted into the bunker compartment to a height of 26 meters. For this purpose, the fencing of the temporary end of the main building of the station and the wall panels were dismantled, an additional overpass was constructed. In the works on lifting the deaerator, more than 30 people were involved. The work on assembling the boiler is continuing, the frame units are mounted and installed. Installed about 300 tons of metal structures. In the turbine shop, the installation of armored frameworks and formwork of columns of the upper structure of the turbine unit base is being carried out. At the construction site of the cooling tower, concrete work was performed on the bases for the foundations of the cooling tower shell, and the backfilling of the excavation was carried out. The works on the crane and railway construction have been completed, the turbine oil emergency drainage tank is being installed.
Every day more than 250 people and 30 units of equipment work on construction sites. Works are conducted in two shifts. At the end of September, the factory acceptance tests of the already completed turbogenerator were successfully completed, and the production of a steam turbine is being completed. They will be delivered to the site at the beginning of 2015. Supply of a block transformer and an auxiliary transformer is scheduled for May 2015.
After the construction of the 2nd stage, the installed electric capacity of the station will increase by 120 MW and will amount to 400 MW, thermal capacity - by 188 Gcal / h, up to 1005 Gcal / h. The annual output will reach 464 million kWh, and the annual electricity supply will amount to 427,0 million kWh. The fuel for the station will be coal from the Erkovetskiy open pit (Amur Region). Completion of construction is scheduled for the end of 2015. The construction of the second stage of the Blagoveshchenskaya CHPP out of 50 billion rubles allocated for new power facilities in the Far East accounted for 6,3 billion. The total cost of the project is 8,2 billion, the remaining 1,9 billion are investments of the RusHydro Group.
