Reconstruction of the boiler house "PivnGZK No. 2" with the installation of a solar power plant (SPP) and storage tanks at the address: 50000, Ukraine, Dnipropetrovsk region, Kryvyi Rih, Volodymyr Cherkasov Street, 31K
The working project, as an energy saving measure, envisages the installation of a cogeneration gas piston unit (CPU) of the AVUS 500plus type - a complete set of equipment for the combined production of electricity and heat by burning natural gas. The cogeneration unit (CPU) is designed to meet the boiler house's needs for electricity, both in emergency mode when the external power supply disappears, and in normal operation. This facility is a complex of engineering structures for generating thermal energy from a boiler room and transmitting it to the end consumer. The AVUS 500plus gas-piston cogeneration plant is a finished product supplied by the manufacturer in a fully equipped form with all technological, construction and fire protection systems. This project does not develop the internal systems and equipment of the CHP. It is planned to connect the CHP to the gas, heat and electricity supply networks. The nominal electrical capacity of the CHP is 600 kW, voltage class 0.4 kV, frequency 50 Hz. The total thermal capacity of the CHP is 639 kW. Volumetric flow rate of natural gas is 139.1 m3/h.The containerized CHP is installed outside on the site within the territory of the boiler house. Communication outlets – through the walls of the container. Flue gas is discharged into a complete flue pipe, 10.5 m high. Natural gas is used to produce electricity and heat, which is supplied to the CHP via a designed pipeline from the existing gas pipeline with a regulator installed to reduce the pressure to the calculated one. Thermal energy is utilized during CHP operation by heating the coolant of the return pipeline of the boiler house's heat network through a heat exchange module.This working project provides for the reconstruction of the RP-6kV electrical networks of the boiler house "PivnGZK No. 2":- replacement of 16 RP-6kV TP-7 6/0.4kV KSO cells with 14 MVC cells. with vacuum circuit breakers with a rated current of 1250A;- replacement of panels Shcho-90 TP-7 6/0.4kV - 11 pcs. with 18 pcs. PowerLine-1000 panels (low-voltage complete device) with automatic circuit breakers with electronicdisconnector;- for the needs of RP-6kV, installation of a self-service switchboard (ShVP-RP with ATS) individually manufactured is provided.
A transformer substation building has been designed for installation of power transformers. The degree of fire resistance of the building – II.
The cogeneration unit (CHP) is designed to meet the boiler house's electricity needs, both in emergency mode when the external power supply disappears, and in normal operation.To increase the useful effect of the CHP operation, it is planned to use the thermal energy released from the CHP to heat the return network water.CHP characteristics:Nominal electric power 600 kW, voltage class 0.4 kV, frequency 50 Hz;Total thermal power 639 kW.Equipment composition:1. The container-type external cogeneration unit is installed on the street, on the side of axis A of the existing boiler house, on one foundation plate with a cooler.2. The MT-639 type heating module is installed on the street, on the A axis of the existing boiler house.
Ensuring reliable and energy-efficient heat supply to consumers using modern technologies;reducing natural gas consumption by introducing cogeneration of heat and electricity;optimizing costs for fuel and energy resources and reducing operating costs;reducing the negative impact on the environment by reducing emissions of greenhouse gases and harmful substances;increasing energy independence and reducing the load on city electricity networks;creating a modern, reliable and sustainable heat supply system that meets the requirements of energy saving and sustainable development.
