Iron or sintering process with reduced emissions of toxic gases

摘要

A method of sintering iron ore comprises the sequential steps of producing a sinter feedstock by substantially homogeneously mixing inter alia iron ore with 0.01 to 0.09% by weight of a solid compound which releases ammonia on thermal decomposition, depositing said feedstock onto a moving grate and combusting the same to produce sintered products rich in iron. Hereby the generation of toxic combustion by-products of the sinter process, i.e. dioxins and furans, may be suppressed. <IMAGE>
