The　MSWI　process　offers　numerous　advantages,　including　a　high　reduction　rate,　rapid　treatment　speed,　and　onsite　incineration.　However,　under　unstable　operating　conditions,　particularly　in　cases　of　fluctuating　furnace　temperatures,　the　concentration　of　discharged　particulate　matter　may　exceed　the　required　emission　standards.　To　better　understand　the　characteristics　of　particle　concentration　at　normal　incinerator　temperatures,　a　practical　municipal　solid　waste　incineration　(MSWI)　process　in　Beijing　was　simulated　using　2D　numerical　simulation.　The　incinerator＇s　structure　is　outlined,　and　a　two-dimensional　Computational　Fluid　Dynamics　(CFD)　model　of　the　incinerator　is　developed.　Based　on　actual　process　parameters,　experiments　were　conducted　under　benchmark　operating　conditions.　The　gas　composition　and　particle　concentration　characteristics　under　normal　temperature　conditions　are　analyzed.　These　findings　can　support　the　optimization　of　control　strategies　for　real-world　MSWI　processes.　©　2024　IEEE.
