Integrated Iron and Steel Works Zaporizhstal completed the project and started the industrial tests of basic coal store of pulverized coal injection complex in blast furnace production. The full volume of investments into the PCI project implementation is about UAH 1 billion including basic coal store UAH 350 million.
The modern high technology basic coal storage of PCI complex of JSC Zaporizhstal doesn't have analogies in Ukraine. The capacity of basic coal storage let to transport 1000 tonne of coal per hour or 300 railway cars per day.
The completion of the project of PCI complex, including the erection of basic coal storage gives sizable energy saving effect to the works. There is no need to use more than 300 million cubic meter of natural gas per year in blast furnace technology anymore.
Mr Rostislav Shurma DG of JSC Zaporizhstal said that "Technology of PCI injection at Zaporizhstal is successfully implemented. We completely refused from the use of natural gas in blast furnace practice and decreased the consumption of metallurgical coke from 495 to 376 kilogram during smelting of 1 tonne of iron which permitted us to decrease the prime cost of iron smelting by USD 50 per tonne or by 15 %.”
There is ecological effect from implementation of the project decreasing of coke consumption would permit to the Steel Works to reduce the emissions of greenhouse gases to atmosphere on the order of 300 thousand ton/year, in conversion to ÑÎ2.
Implementation of the PCI project started at Zaporizhstal at the Q1 of 2008, and in October 2011 the unit was put into operation. Total investments from 2008 to the PCI project including the completion of the Basic Coal Store construction in November 2012, was approximately UAH 1 billion. Implementation of PCI unit was repaid during 1.5 year.
It is necessary to notice that 88 new working places are established at the Works as a result of completion of basic coal store construction for PCI complex. In addition, training of employees of the enterprise who should work on new equipment has been carried out.
