Abstract
The authors have established the aim of mathematical modeling of gas dynamics and steady-state heat transfer in layer shaft furnaces, in which the gas stream moves to a complex system of curved channels of variable curvature and cross-sectional area. The problem of the development of complex mathematical models of layer metallurgical furnaces and units is to obtain the equations of gas flow in the moving bed, linking average speeds at space between pieces (true speed), its actual pressure and temperature, as from these values depends the intensity of physical and chemical transformations. The solution to this problem is performed using a parallel between the passage of the gas in the bed and the movement of a hypothetical fl uid, which occupies the entire volume of the device, including the amount of lump materials.
