At present time, sintering flue gas denitration adopts mainly active carbon (coking) adsorption technology, high investment and operation costs are required. Flue gas denitration technology of SCR (selective catalytic reduction) is applied widely in coal-fired boilers, the technical maturity is credible. Based on the characteristic of sintering flue gas in iron and steel plant, the paper sees that flue gas denitration technology of SCR is applied in sintering flue gas denitration. Through the proper technique optimization and technical innovation, denitration technology of SCR is feasible and applicable when the sintering flue gas is applied.
