Ruukki to Install New PCI System at Raahe Blast Furnace
04/09/2014 - Rautaruukki is to replace the blast furnace oil injection system at its Raahe steel mill with a new pulverized coal injection (PCI) system.
The aim is to improve steelmaking cost efficiency by reducing raw material costs. The total investment will be around € 65 million and will be spread over slightly more than two years. In addition, work is underway on replacing the converters in the steel plant at the Raahe Works in Finalnd.
The PCI system will replace the existing oil injection system, which has been in use in the blast furnaces since 1987. With PCI, finely pulverized coal dust is injected into the blast furnace through the hot blast tuyeres. The coal will replace more expensive injection oil and coke. Injection coal is the most commonly used additional reduction agent in blast furnaces to save coke.
Claudius Peters Projects GmbH, which is part of the Claudius Peters Group, has been selected to supply the injection system. Claudius Peters Group designs and manufactures innovative material handling and processing systems for many industrial sectors, as well as coal pulverization and injection systems for the cement, steel and aluminum industries and for power production Claudius Peters Group GmbH is a wholly owned subsidiary of Langley Holdings plc, a privately owned multi-disciplined UK engineering group.
The new system will be brought into use during the second half of next year. The new technology will have no impact on the workforce. Also the environmental impacts will be minor — carbon dioxide emissions will decrease, whereas dust emissions will increase slightly and also electricity consumption will grow.
The project involves coal storage, handling, drying and pulverizing systems, which will be located in the immediate proximity of the blast furnaces. Construction work associated with the project can take place whilst production is running. The degree of domestic origin of the investment will be around 65% and design, construction and installation work will have a direct impact on employment in Finland of around 430 person-years.
Work is also underway at Ruukki's Raahe Works on replacing the converters in the steel plant. The existing converters are 26 years old and will be replaced by modern, more cost efficient converters. The project is worth about € 22 million and is scheduled for completion by the end of 2015.
