Description
Summary:The stove of a blast furnace is one of its most important elements, helping to make the furnace more efficient by preheating the blast. Blast-furnace stoves operate as a unit in order to provide a continuous supply of hot blast to the furnace, this being done by alternating the stoves between cycles in which they heat the blast and cycles in which their checkerwork is heated. Fixed cycles are often used due to the difficulty of operating stoves in cycles of different durations. However, this practice inevitably leads to fuel losses and destabilizes the temperature of the blast. This article presents a model of heat transfer that the authors have developed for a blast-furnace stove. An alternating cycle for heating the blast with a group of stoves is analyzed and methods are proposed for solving problems concerning operating cycles with the use of a three-stove or four-stove group.
