EGR 시스템을 적용한 린-리치 연소시스템의 공해물질 배출 특성 연구

초록

Lean-rich combustion system was composed both fuel-lean and fuel-rich flame at once. Each of fuel-lean and fuel-rich combustion types to reduce Thermal NOx and obtain flame stability. This study was confirmed a stability of flame through variation of flame shape that EGR was applied and compared the emission characteristics of EGR lean-rich combustion system to normal premixed combustion system at real condition to review a utility of the system. As a result, emission index of NOx and CO generated from EGR lean-rich combustion system at global equivalence ratio is 0.85 just half level(NOx 0.31 g/kg, CO 0.08g/kg) compared to the amount generated from normal premixed combustion system at equivalence ratio is 0.78.
