Enhancement of the energy efficiency of electric steelmaking processes by means of natural gas conversion with the exhaust gases of an arc furnace
Journal Title: Проблеми загальної енергетики - Year 2017, Vol 0, Issue 1
Abstract
We have developed a new scheme of the electric steelmaking process with thermochemical recuperation, i.e., natural gas conversion with the exhaust gases of an arc furnace for scrap preheating. Thermodynamic calculations show that this scheme provides an increase in the thermal efficiency of the furnace by 5–6%, fuel economy by 21%, and a decrease in CO2 emission to the atmosphere by 9.8%.
