The circulating fluidised bed boiler from Valmet will be installed and operational within three years. The fluidised bed boiler burns coal more efficiently than the current coal fired boilers and has a guaranteed efficiency of more than 92%, while producing very low emissions. It is equipped with facilities for desulphurisation and reduction of nitrogen oxides emissions. All coal-fired boilers at the Ostrava power plant are being either replaced or overhauled. While the turnkey boiler project will be realised by Valmet, the desulphurisation and the de-nitrification facilities will be delivered by a number of Czech companies.
ArcelorMittal Ostrava is to build a new boiler as part of a USD 150M modernisation programme for the steelmaker’s power plant. Through its subsidiary ArcelorMittal Energy, a contract has been signed with Finland’s Valmet to install a fluidised bed boiler worth USD 74M, replacing four coal-fired boilers. The new boiler, which is more energy-efficient, will significantly reduce emissions of sulphur dioxide, nitrogen oxides and dust.
Along with the site’s ongoing desulphurisation programme and its project to reduce nitrogen oxides, the new boiler is a part of the overall modernisation of Ostrava’s power plant. These investments will help reduce the company´s environmental footprint and ensure its power plant will comply with the European emission limits before they come into effect.
