The analysis of scientific publications containing information about the equipment and methods of modeling the process of pulverized fuel combustion is carried out. The basic requirements for ensuring the reliability of research results are formulated. The conclusion is made about the possibility and expediency of using installations of the type "vertical tubular furnace" to find ways to increase the completeness of pulverized coal combustion in the blast furnaces raceway. Emphasis is placed on the importance of ensuring a uniform supply of fuel to the reaction zone, a time-stable ratio of fuel and oxidant, qualitative technical analysis of the source fuel, as well as the residue after its combustion. Based on a comparative analysis of methods for determining the completeness of burnout of pulverized fuel used in such studies, a convenient formula for its calculations is proposed.
