Abstract

Language:

In the present paper, the investigation of post-reaction gas afterburning generated during metallurgical processes utilizing carbon for the reduction of metal and semi-metal oxides is discussed. The study aims to explore the potential of process waste gases as an alternative energy source either for reuse in the same process or for conversion into other forms. The findings indicate that chemical enthalpy accounts for 93% of the total energy stream of the post-reaction gas, with the remainder attributed to physical enthalpy. The methodology involved meticulous attention to the mixing of fuel and oxidizer, as well as maintaining an appropriate excess combustion air ratio (λa). Various combustion dynamics models were evaluated, ultimately revealing that a two-step mechanism with reaction constants based on the Westbrook-Dryer model yielded the most accurate results. The implications of this research emphasize not only energy conservation but also the environmental benefits of optimizing waste energy utilization in metallurgical operations.
