Substitution of Coke and Energy Saving in Blast Furnaces. Part 1. Characteristics of Technology and Uneven Processes―Cognition, Calculation, Forecast
Blast melting is one of the few industrial technologies that preserve the essence and significance by all technical revolutions. This phenomenon exists due to certain properties of the system that ensures exponentially increasing the productivity and linearly lowering the coke rate, that seeks to 200-250 kg/thm. The solution of problems of blast-furnace smelting involves the solution of two analytical tasks: study of the relationship of real parameters and characteristics of the blast melting; forecast of expected parameters and processes on preset parameters of work of the blast melting.
The first task is solved on the basis of balance equations of conservation of mass and energy, the second-based on the method of numerical modeling of processes in radial annular cross-sections along the height of the furnace: multi-zone model of heat-and mass transfer; physico-chemical transformations and mechanics of material and gases. During the numerical and analytical investigation it was shown that the peripheral part of the blast furnace is characterized by the minimum process of direct reduction and also shown that the uniform distribution of burden load provides the minimum fuel consumption.
