Kametstal plant of Metinvest mining and metallurgical group, established at Dneprovsky Iron and Steel Works (DMK, Kamenskoye, Dnepropetrovsk region), implements energy-efficient project to reduce electricity consumption during blast furnace gas transportation.
According to the press release, a project to replace the blower (gas blower) is being successfully implemented at Gas Booster Station (GBS) No. 6 – as part of the mill’s cooperation with YASNO Efficiency.
The new single-stage blower (gas blower) will make it possible to significantly save electric energy in the technological process of blast furnace gas transportation of the required parameters of productivity and pressure for the rolling process.
At present, one of four gas blowers is constantly in operation at GPS-6 to ensure production of the rolling mill, which transports blast furnace gas to the heating furnaces of the pipe-forming mill. The rated power of the gas blower is 850 kW, the necessary parameters are adjusted manually, which reduces the stability of maintaining the required productivity and pressure of blast furnace gas in the gas pipeline, as well as at the same time the consumption of electricity is 650 kWh on average.
The specialists implemented solutions for installation of a new energy-efficient modern blower using the maximum amount of available technological equipment. Now specialists of the contracting organization are carrying out works on dismantling of the existing gas blower, relocation of existing communications, reconstruction of electrical premises with installation of new equipment on the existing industrial site.
The blower will be powered directly to the power supply cell in the substation room, and a new cable line will be laid from the substation to the GPS-6 room. Gas blower capacity and pressure regulation will be ensured by the installed guide apparatus and a 0.4 kV frequency converter. The control systems are individually designed on the basis of Siemens controller for automatic operation in the specified capacity range.
“Average power consumption taking into account the efficiency of the electric motor and control system of the new gas blower is approximately 200 kWh, which is three times less than the current power consumption, as well as it is the stability of parameters and improvement of working conditions of apparatusmen. Implementation of such energy-efficient solutions allows to achieve tangible energy savings and significantly reduce the company’s expenses on energy costs, which is especially important in the difficult times of martial law in the country,” the press release explains.
“Kametstal” was created on the basis of PJSC “Dneprovsky Coke and Chemical Plant” (DCCP) and CEC of PJSC “Dneprovsky Iron and Steel Works” (DMK).
According to the report of Metinvest Group’s parent company for 2020, Metinvest B.V. (Netherlands) owned 100% of DKHZ shares.
