“…In this work, we applied numerical simulation of kilning aggregates lining. The mathematical model used by us did not take into account heat transfer in the axial and transverse directions with respect to the kiln channel (determined by different structures of the central and peripheral sole parts) as well as heat exchange between the kiln wall and sole through its side face (Utenkov et al, 1991;Tomilin and Chichikalo, 2011;Nikitin et al, 1969). The model of linings of a high-temperature tunnel kiln is presented in Fig.…”

The features of heat and mass transfer inlining of high-temperature tunnel kiln for the burning of refractory materials are revealed by numerical simulation of heat transfer processes. Use of modern computer calculation programs permits to choose optimal constructions of trolley walls and heart lining. This ensures improved hermeticity of workspace and 15-20% reduction of heat loss. We studied the operation of a hightemperature of the unit with a combined system that ensured efficient burning of natural gas as well as regulation of temperature regime in the thermal aggregate workspace. A procedure was advanced to calculate consumption of fuel by gas burners and hot air over burning zone positions of high-temperature tunnel kilns when using a combined system of natural gas burning. The heat work of a tunnel kiln was optimized. This permitted to supply maximal quantity of hot air and natural gas into the initial positions of burning zone of tunnel kiln and to ensure technologically required temperatures of products burning (1780-1800ºС).
