摘要

The dominant source of CO_2 emissions from the steel industry and in particular for integrated cycle is the reduction processes [1], however, the contribution from heating processes is far from to be negligible considering that each piece of steel is on average heated twice on its journey through the production chain. Having this in mind the R&D project "CO_2 reduction in reheating furnace" or CO2RED started in 2006 with the financial grant from the Research Fund for Coal and Steel (RFCS) of the European Community and with the goals: (1) to investigate the capability of new technology, such as regenerative and oxy-fuel combustion system based on flameless oxidation to allow a step change in environmental impact of steel reheating furnaces reducing at the same time the CO_2 and NO_x emissions in comparison with conventional furnaces equipped with central recuperator and flame burners; (2) to give recommendation to the steel industry for the best practice to install and operate with high reliability the new combustion systems in big size reheating furnaces for different types of gaseous fuels; (3) to analyse the effect of new combustion systems on the product quality.
