Essay

The dissertation focuses on the selection of the major technological and designing parameters that determine operation of compact regenerators for industrial furnaces. Numerical-analytical model of thermal and gas-dynamic processes of compact regenerator operation has been worked out on the basis of Shuman's analytical solution for heat exchange in the fixed bed of material. To study the operation of regenerative ball filling a unit has been made and experimental research has been conducted to investigate the regenerator's work in unstable conditions. The mathematical model has been adapted by comparing computational and experimental temperature values of material, flue gases and air, as well as hydraulic resistance of the filling. Analysis of experimental relations and computational values confirms the adequacy of the mathematical model to real physical processes, taking place in the regenerator. The technique of selecting design and technological parameters of compact filling operation has been work ed out which ensures the most productive work of regenerator in conditions of change in heat capacity of the furnace. Numerical research has also been applied to the work of combined filling that presupposes substitution of metal balls for the corundum ones in its lower part. The influence of the compact regenerator filling shape on the efficiency of its operation has been investigated. The range of ratio between the upper and the lower cross-section of the filling has been determined which allows to reduce the filling resistance without the change in air heating temperature and in the level of combustion products heat regeneration. For the investigated range of regime parameters recommendations have been worked out for selecting the shape of the filling to be a truncated pyramid with the optimum ratio of its bases. By using the obtained methods of selecting design and technological parameters of compact regenerator work a technical project has been made that is concerned with the reconstruction of 4 furnaces by means of regenerative burners installation in the wire-production workshop at Dniepropetrovsk Hardware Plant.
