Municipal　solid　waste　incineration　(MSWI)　processes　produce　particulate　matter　that　can　cause　air　pollution.　Understanding　the　formation　mechanism　of　particulate　matter　(PM)　inside　the　furnace,　in　terms　of　pollutant　generation　sources,　is　crucial　for　pollution　reduction　and　optimal　control.　This　article　proposes　a　numerical　simulation　model　to　analyze　PM　generation　inside　the　MSWI　furnace　under　benchmark　operating　conditions,　by　coupling　several　software　tools.　Initially,　the　MSWI　process　is　analyzed　to　identify　key　variables　affecting　PM　generation.　Subsequently,　a　numerical　simulation　model　of　PM　generation　in　the　incinerator,　integrating　FLIC　and　FLUENT　software,　is　developed.　The　flow　field　distribution　and　PM　concentration　under　benchmark　conditions　are　then　analyzed.　The　effectiveness　of　this　method　is　validated　using　actual　data　from　an　MSWI　plant　in　Beijing,　providing　practical　insights　for　reducing　PM　concentrations　through　process　improvements　and　optimal　control.　©　2024　IEEE.
