NOX reduction in calciner using air staging and raw meal split technology

摘要: Abstract The manufacture of cement is highly energy-intensive and emission-intensive due to the large heat needed for plant. Nitrus Oxide ( N 2 O ) one major greenhouse gas emitted into atmosphere through it. purpose this work reduce NOX emissions inside calciner by using air staging raw meal split technology. Tertiary enables fuel be combusted in two different areas. Three cases are simulated three flow rate tertiary CFD software. also passed zones. In order gain confidence model used, non-premixed coal combustion modeled validated experimental data presented literature. Based on results predicted, performance analysed depth. When quantity upper inlet increasing formation decreasing. By comparing it found that case 70%–30% air-flow lower respectively 362 ppm produced, which less than other cases.
