Ansys Fluent 18.2 software was used to simulate PAO NLMK air tuyere functioning. It was established that 5 degrees hot air feed angle and 22 mm inner nipple diameter for natural gas feeding are rational. It was recom-mended to increase coal dust fuel feed angle till 20 degrees, to decrease dis-tance between natural gas nipple and flange till 30 mm.
