In　the　actual　utilization　of　geothermal　resources,　the　scaling　of　geothermal　fluids　is　one　of　the　most　important　factors　affecting　the　efficiency　of　geothermal　power　generation　and　even　causing　the　shutdown　of　power　generation　systems.　In　this　paper,　the　key　factors　affecting　the　formation　of　fouling　of　geothermal　fluids　in　heat　exchange　pipelines　and　the　characteristics　of　sedimentation　evolution　are　explored,　and　the　influence　of　fouling　thermal　resistance　on　system　efficiency　is　reduced　by　optimizing　the　operating　parameters　of　the　system　and　adding　antiscalants.　In　this　paper,　it　is　proposed　that　the　power　generation　is　maintained　within　the　acceptable　range　by　increasing　the　flow　rate　instead　of　shutdown　maintenance　and　cleaning,　and　the　flow　rate　is　increased　at　1,　3　and　5　days　of　system　operation,　and　the　system　pump　consumption,　expansion　work　and　net　power　generation　of　the　system　all　surge,　and　then　decrease　with　the　change　of　time,　until　the　dirt　generation　state　reaches　equilibrium　again,　and　the　average　net　power　generation　under　increasing　flow　rate　is　greater　than　the　power　generation　without　changing　the　flow.　©　2023　IEEE.
