PROCEDIMIENTO DE INYECCION DE CANTIDADES DOSIFICADAS DE MA- TERIAS PULVERULENTAS E INSTALACION CORRESPONDIENTE

摘要

A fuel stream comprising a combustible pulverized material entrained in a carrier gas is formed and subsequently injected into a blast furnace with the hot blast air without any detrimental effect on the hot air blast and with minimum energy consumption. The volume flow rate and pressure of the carrier gas are controlled as functions of the furnace pressure and the pulverized material feed rate is simultaneously controlled as a function of the carrier gas pressure drop.
