In the paper are presented the possibility of using axial and radial diffusion burner in rotary furnace. Both types of burners allow secondary air combustion, combustion quality measure is the ratio of primary and secondary flame. Experimental comparison of both types of burners has been performed with the high-revolution rotary furnace. On this basis, benefits have been identified and their use possibilities.

The contemporary shaft furnaces for the production of sintered magnesia have a very good performance. However, there are still significant possibilities of their improvement. Thermodynamic, hydrodynamic and rheological processes don't run optimally. The purpose of the research was to determine the reasons and realization of optimization measures. One of the significant requirements was to process materials with lower granularity (20 -40 mm). The improvement was focused on the charging system modification, burner system modification, coke utilization in the central part of the furnace, sinter heat utilization, increasing the insulation. Their verification was reached at the operational conditions. The result was conceptually new pilot shaft furnace, determined for the further research. The basic features of the new shaft furnace are distributed burners improving combustion of the secondary air flowing through the central part of the furnace. By this approach significant improvement of the temperature homogeneity through the furnace cross section is achieved.
