Abstract
Experimental investigations have been conducted to promote turbulent thermal mixing of hot gas and cold airflow in a simulated sintering gas preheating unit. Six perforated pipes with different inclined jet angles were tested in the experiments. A comparison between numerical simulation and experimental results was provided for more accurate analysis. The results showed enhanced mixing between jets and crossflow for the inclined injection pattern. Moreover, the results revealed that the inclined angle performed an important role in jet penetration and hot gas dilution. Mixing performance was analyzed by measuring velocity, temperature, and concentration fields. Moreover, the root mean square deviation coefficient was employed to quantitatively evaluate the three types of distribution fields. The jet hole configuration of 120° achieved the best mixing performance. In the measuring plane located at 4.25 times the distance of the main flow duct hydraulic diameter from the perforated pipe, the mixing non-uniformity of temperature, velocity, and CO concentration were 0.10, 0.07, and 0.15, respectively.
