07/05/2012 - At the PJSC Ilyich Iron and Steel Works, Metinvest is finishing a great building of the pulverized coal injection unit. An idle run is being practiced at the pulverized coal injection unit and full operational tests should begin this month.
At the PJSC Ilyich Iron and Steel Works Metinvest is finishing a great building of the pulverized coal injection unit. A delivery contract with the Chinese company MinMetals was signed by the combinat’s direction in 2006, but because of the crisis in 2008 its realization was stopped. After joining the group of Metinvest in 2010 the building was recommenced.
The idle run is being practiced at the pulverized coal injection unit at the moment. Basic processes connected with the end of the building and commissioning are being held parallel. In June a step-by-step activation of the power system units was began. After trial run is over an adjustment of equipment in complex with the monitoring instruments and automatics system with the participation of Siemens and MinMetals experts will begin. At the present point in time an adjustment of the automated control systems by means of technological processes at the main auxiliary equipment of the pulverized coal injection unit with all units and systems is carried out from the central supervisory console. In July specialists are intended to proceed to full operation tests of the pulverized coal injection unit.
Taking into account high prices for natural gas and its deficit and the fact that it is needed in great amounts for blast furnace production, the necessity of introduction of the pulverized coal injection technology in the BFs at our enterprise is extremely urgent, underlined Vladimyr Boyko, the general manager of the Ilyich works. The introduction of the pulverized coal injection unit into the power system of the enterprise is planned by the end of 2012. The investment amounts to US$150 million, but the company hopes that it can reduce its use of natural gas in BFs and also shorten elementary discharge of coke for every generated ton of cast iron,.
The project foresees the introduction of dust suppression technology by nitrogen at the casting beds and modernization of the gas supply control system to the air heaters – these systems will be activated at the same time with introduction into operation of the pulverized coal injection unit. The main part of enclosure - direct installation - foresees an airtight circuit of breakage of coal and the supply of pulverized coal into blast furnaces and also the equipping of coal mills, pick-and-place assembly units, bunkers of the closed coal storage with the modern aspiration systems from the leading manufactures from Russia and Poland.
