Abstract
Sistema para la mejora energética en un horno rotativo de fusión por oxicombustión para la fabricación de fundición de hierro, de los que utilizan una relación aproximadamente estequiométrica de gas combustible y oxígeno, que se caracteriza porque se dispone a la salida del horno de los gases de la oxicombustión, analizadores que cuantifican la presencia de CO, O{sub,2 y CO{sub,2 en dichos gases, de modo que si se da alguna de las siguientes condiciones de desfase: CO>10% ó O{sub,2 > 5% ó CO{sub,2 <70% y alrededor de los 550ºC, y a medida que aumente la temperatura, se ordena a unos reguladores de las fuentes de alimentación de] horno que aumenten progresivamente el caudal de oxígeno (QO{sub,2 ) mientras se de alguna de las condiciones de desfase, no debiendo ser el caudal de (QO{sub,2 ) superior a cinco veces el caudal de gas de combustión (Qgas): QO{sub,2 /Qgas<5. De aplicación en la fabricación de fundición de hierro.System for energy improvement in a rotary oxy-fuel melting furnace for the manufacture of cast iron, of which use an approximately stoichiometric ratio of fuel gas and oxygen, characterized by the fact that gases from the furnace are disposed at the furnace exit oxy-fuel, analyzers that quantify the presence of CO, O {sub, 2 and CO {sub, 2 in these gases, so that if any of the following lag conditions occurs: CO> 10% or O {sub, 2 > 5% or CO {sub, 2 <70% and around 550ºC, and as the temperature increases, regulators of the furnace power supplies] are ordered to progressively increase the oxygen flow (QO {sub, 2) while some of the phase shift conditions are present, the flow rate of (QO {sub, 2) should not be more than five times the flow rate of combustion gas (Qgas): QO {sub, 2 / Qgas <5. Applicable in the manufacture of cast iron.
