Three-dimensional Dynamic Simulator for Blast Furnace
Three-dimensional dynamic mathematical model which is constructed as a simulator of an actual blast furnace is developed based on the mass, momentum and energy conservation in the furnace. In this paper, following things are investigated.<br>(1) The wholesome of this mathematical model is clarified checking the total mass and energy conservation.<br>(2) Then, comparison with simulated and measured results for steady state is done for actual operating conditions in order to clarify the validity of this simulator.<br>(3) Dynamic behavior of the blast furnace such as the blown-in/off operations which are most hardly estimated is simulated by this model.<br>(4) The effects of the shape of a blast furnace on the operating results such as total pressure loss, fuel rate and so on are investigated by this model.
