Analýza důsledků injektáže uhlovodíkových paliv na základě energetické bilance vysoké pece

Abstract

Application of the material and heat balance for the analysis of the impact of alternative fuel injection into the tuyeres of the blast furnaces. There is an briefly overview given afterwards. Theoretically the lowest possible specific consumption of coke based on thermodynamic equilibriums of the reduction processes was set from the balance of the bottom zone. There were calculated expected and real consumption of the coke on its basis, also degree of reduction, coefficients of substitution for the coke and other indicators for the various fuels. New innovated graphic way of the evaluation of heat and reduction work of the furnace was designed. The effect of increased content of hydrogen in the furnance was analysed from the thermodynamic aspect.
