Heating networks

In order to ensure reliable coverage of existing and future loads in the area of Vitebsk adjacent to the Vitebsk CHPP, the project “Heating main from the Vitebsk CHPP to the Luchesa microdistrict” with a loopback with the Southern Heating Main in the TK-19L area and with the Central Heating Main in the TK-11Ts area in Vitebsk" provided for the construction of a new section of the heating main overground and underground for transporting network water from the Vitebsk CHPP to the Luchesa microdistrict (2ø700, 2ø600 with a length of 5.25 km) with the crossing of the Western Dvina River along the spans of the existing KIMovsky automobile bridge. The intersection of the embankments of the railway track to the city of Orsha and the reserve roadbed of the Vitebsk-Medvedka section was carried out above ground on high supports with a two-span crossing on trusses, spans 41 + 41 m. Construction of stages 1 and 2 was carried out in 2010-2011.

In 2010, the project “Main heating network for heat supply of residential micro-districts “Kiselevichy” and “Zapadny” under construction in Bobruisk” was developed. At the same time, the area of Bobruisk CHPP-2 is expanding and includes the area of the Kiselevichi boiler house, which is being taken out of operation, taking into account the heat load of the future development - 70 Gcal/h. The project provides for the construction of a heating main 2ø500 from TK 1108 to the Kiselevichi boiler house, above-ground and underground with a total length of 3.5 km, as well as the construction of a booster pumping station in the 3rd stage of construction. Phases 1 and 2 of construction have been completed. The intersection of the Bobruisk-Miradino railway in the area of the Kiselevichi stopping point is provided above ground on high supports with a pipe crossing in two sleeves with a diameter of 1620x12, a span of 45 m. The height of the pipe crossing above the head of the railway track is 12.4 m, taking into account the electrification of the railway section. To maintain the existing hydraulic mode in which consumers of the Kiselevichi boiler house operate, a control unit with a direct-acting pressure regulator is provided. Construction of stages 1 and 2 was carried out in 2011-2012.

In 1974, the implementation of a heat supply system of Minsk with a population of more than 1 million residents began at the suburban thermal power plant (currently Minsk CHPP-4). The project provided for the use of existing city boiler houses for operation in peak mode in conjunction with Minsk CHPP-4, the use of an increased temperature schedule for network water (180-70 ° C) in transit pipelines with a diameter of 1200 and 1400 mm. The estimated heat supply from thermal power plants and boiler houses is 2000 Gcal/h. For the work performed, the team of RUE "Belnipienergoprom" in 1983 was awarded the prize of the Council of Ministers of the USSR "For the design and construction of a heating complex in the city of Minsk." Currently, the complex includes Minsk CHPP-4 (1035 MW, 1519 Gcal/h), five peak boiler houses: Kharkovskaya (310 Gcal/h), Zapadnaya (190 Gcal/h), Orlovskaya (195 Gcal/h), Kurasovshchina (225 Gcal/h), Masyukovshchina (245 Gcal/h) and 62.2 km of heating networks with a diameter of 1400 - 800 mm.

In 2000, the project “Heat supply from the Mozyr CHPP to the city” was implemented. Main heating networks". The project provided for the construction of an overhead heating main 2Du800 mm, 17 km long, in a two-pipe design on separate supports with the intersection of highways and tram tracks along bridge crossings.

In 2001, the heating networks department developed a project for the construction of a new heating main 2Du600 mm from the district boiler house to the city of Soligorsk, with a length of 3.0 km from pre-insulated pipes. The heating main partially fell into the zone of influence of mining workings, which was taken into account during the design. To compensate for temperature expansions, the method of preheating pipes before backfilling with soil and starting compensators were used for the first time in practice. The project was implemented in 2002.

In 2011-2012 were developed 2 projects : “Construction of the heating main Gomel CHPP-1-ul. Sevastopolskaya in Gomel" and "Transition of the heating main across the Sozh River using the structures of the steel-reinforced concrete structure of the existing road bridge across the Sozh River in Gomel." The projects solved the important national economic problem of supplying heat to the Novobelitsa micro-district under construction from the Gomel CHPP-1, which provided for the construction of a 2Du500 overhead and underground heating main with a total length of 2.7 km. The crossing of the heating main across the Sozh River was carried out using the steel-reinforced concrete structures of the existing road bridge on the Frunze street. The construction of the heating main was carried out in 2012-2013.

For reliable heat of beyond river Neman part of the city when the heat demand growth due to housing development and decommissioning of small boiler stations main pipeline М-14 2Du700мм mm was designed and constructed with pipelines laying across the river Neman in the structures of existing of "Rumlevskiy " bridge. At the final stage of construction is heating main 2Du500 mm (with upload pumping station), which loops around M-4 and M-14 . In the future, it is planned to construct the third heating main of beyond river Neman part of the city due to the increase of heat load of the Yuzhniy District ( up to100 120Gkal / h).

In 2014, RUE “Belnipienergoprom” developed the project “Development of the South-Western residential area No. 5 in Brest. Main heat supply networks.” The project provided for the construction of a 2Du500 mm main network, 4 km long, connecting zones of the Southern District Boiler House and the Brest CHPP and providing heat supply to the South-Western residential area of Brest from the Brest CHPPt. A special feature of this project is the solution to the problem of constructing an underground heating main from pre-insulated pipes in the flooded areas of the Mukhovets River floodplain and the construction of overpasses through two existing and one promising riverbed of the Mukhovets and Zatoka rivers. The heating main construction project was implemented on December 30, 2015.

In 2009, RUE "Belnipienergoprom" developed the project "Construction of a heating main from the Kaliningrad CHPP-2 to the Southern part of Kaliningrad" with heat supply from the Kaliningrad CHPP-2 to the Yuzhniy district of Kaliningrad in the amount of 297 Gcal/h. The project provides: construction of a heating main primary circuit 1Dup800 mm + 2Duo700 mm, 9.3 km long in an above-ground version, including road punctures and the construction of metal trusses for crossing railway tracks, in the section from the Kaliningrad CHPP-2 to the HPS heat pump station; construction of secondary circuit pipelines sections with a diameter of 2Du700 mm from the heating station to connection points to the city’s heating networks, with a length of 2.0 km; construction of a heat pump station, including laying of external power supply cables from the Yuzhnaya substation and the Molokozavodskaya substation, with a length of 7.0 km. The project was implemented on October 21, 2010, when the first stage of the heating main from Kaliningrad CHPP-2 was launched. Construction of the heating main is the largest investment project in terms of capital investments in the Kaliningrad heat and power industry in recent years and the first project of the “Kaliningrad CHPP-2 branch of OJSC INTER RAO UES” in the sphere of heating networks development of the region.

In 2011, the issue of heat supply to the Kazimirovka microdistrict from the Mogilev CHPP-1 was resolved - the projects “Main heating network from pavilion No. 2 on the Khimikov street to VV 8a-7 on the B. Biruli street for heat supply to the residential areas “Sputnik”, “Kazimirovka” in the city of Mogilev” (2ø700, 2ø600 with a length of 2.51 km), “Main heating network from the air connection 8A-7 on the Byalynitsky-Birulya street to the residential area "Kazimirovka" in Mogilev" (including a booster pumping station)" (1ø700 + 2ø500 with a length of 3.4 km (1st stage built - 2ø500, 3.4 km, heat load up to 59.7 Gcal/ h) and “Construction of a booster pumping station for heat supply to the residential area “Kazimirovka” in Mogilev” (PNS - 1150 m3/h). At the same time, two boiler houses were taken out of operation with the installation of a booster (mixing) pumping station on the territory of the OEZ boiler house station that ensures changes in coolant parameters during the heating period. Construction of the facilities was carried out in 2012-2015.
