Title:ResearchandImplementationofSpeedReductionEnergyOptimizationRetrofitforLarge-scaleAxial-flowForcedDraftFansinThermalPowerPlant
Abstract:
Withtheincreasingdemandforenergyconservationandemissionreduction,optimizingtheoperationoflarge-scalethermalpowerunitshasbecomeessential.Thispaperproposesastudyontheretrofitofspeedreductionenergyoptimizationforlarge-scaleaxial-flowforceddraftfansinthermalpowerplants.Theobjectiveistoachieveenergysavingsthroughtheoptimizationoffanoperation,leadingtoimprovedoverallefficiencyandreducedgreenhousegasemissions.
Introduction:
Thermalpowerplantsplayasignificantroleinmeetingtheworld'senergydemands.However,theoperationoftheseplantsalsocontributestoalargeproportionofgreenhousegasemissions.Therefore,itiscrucialtoexploreenergy-savingmeasurestoimprovetheoverallefficiencyoftheseplants.Inthispaper,wefocusontheretrofitandoptimizationoflarge-scaleaxial-flowforceddraftfans,whicharecriticalcomponentsinathermalpowerplant.
Methods:
1.Analysisofcurrentoperatingconditions:Firstly,thecurrentoperatingconditionsoftheaxial-flowforceddraftfanswillbeevaluated.Thiswillinvolvedatacollectionandanalysis,includingfanspeed,powerconsumption,airflowrate,andsystempressure.
2.Optimizationofspeedreduction:Basedontheanalysisofthecurrentoperatingconditions,anoptimalspeedreductionstrategywillbedeveloped.Thisstrategywillaimtoreducethespeedofthefanswhilemaintainingsufficientairflowrateforcombustionandcoolingprocesses.
3.Computationalfluiddynamics(CFD)simulation:CFDsimulationwillbeconductedtoanalyzetheflowcharacteristics,pressuredistribution,andpowerconsumptionofthefansunderdifferentoperatingconditions.Thiswillprovideabasisforoptimizingthefanperformanceandenergyconsumption.
4.Implementationofretrofitmeasures:Theproposedspeedreductionstrategywillbeimplementedintheexistinglarge-scaleaxial-flowforceddraftfans.Thismayinvolvemodifiedfanblades,integratedcontrolsystems,orvariablefrequencydrivestoenableflexibleoperation.
