Abstract
The flameless oxyfuel combustion technology has been proven to be a promising new method to reduce the fuel consumption and pollutants in industrial applications [...]
Highlights
The oxyfuel combustion technology was introduced in the late eighties to target the increasing demand for controlling the CO2 and NOx production in industrial combustion systems
The study was done on a 100 kW test unit and the results showed that oxyfuel produces up to 30% less NOx emissions compared to an identical air-fuel combustion system
The simulation has been done according to the real operational condition of the furnace in the rolling mill, with a 596 kW burner capacity and a lambda value of 1.54
Summary
The oxyfuel combustion technology was introduced in the late eighties to target the increasing demand for controlling the CO2 and NOx production in industrial combustion systems. In this technology, the fuel is combusted in an almost pure oxygen atmosphere instead of using air. This provides the mean for a CO2 sequestration from the flue gases [1] This combustion technology was initially promoted and studied for the usage in coal-fired power plants and coal-combustion applications [2,3]. The International Flame Research Foundation (IFRF) carried out major research in this area, with usage of an oxy-coal combustor with a flue gas recirculation (FGR) system
