When　the　wet　flue　gas　of　a　gas　power　plant　is　discharged,　a　white　wet　plume　of　flue　gas　will　be　produced,　causing　environmental　and　visual　pollution.　Local　governments　require　the　treatment　of　white　wet　Plume　of　flue　gas.　This　paper　establishes　a　model　of　the　process　of　flue　gas　emission　to　produce　white　wet　plume　of　flue　gas,　and　the　numerical　method　is　used　to　solve　it.　The　effects　of　factors　such　as　flue　gas　emission　temperature　and　flue　gas　moisture　content　on　the　generation　of　white　wet　plume　of　flue　gas　are　studied　respectively.　The　results　show　that　the　numerical　simulation　method　has　a　good　simulation　effect　for　studying　the　generation　conditions　and　factors　of　the　white　wet　Plume　of　flue　gas.　It　is　possible　to　obtain　the　limit　emission　temperature　and　the　emission　moisture　content　of　the　flue　gas　emission　without　producing　white　wet　Plume　of　flue　gas.　It　is　possible　to　study　the　generation　of　white　wet　plume　of　flue　gas　under　the　conditions　of　different　flue　gas　emission　temperature　and　emission　moisture　content,　and　provide　reference　and　guidance　for　the　engineering　practice　of　power　plant　flue　gas　reduction　or　elimination　of　white　wet　plume　of　flue　gas.
