Investigation Of The Energy Performance Of Pasta And Macaroni Factory - A Case Of Africa P.L.C M.Sc.

Abstract

The Increased Use Of Energy Has Raised Serious Concern About The Energy Charges And Demand. The Objective Of This Study Is To Investigate Energy Performance Analysis Of Pasta And Macaroni Factory For A Case Of Africa P.L.C Through Energy Analysis. The Detailed Energy Analysis Is Carried Out By Assessing The Performance Of Energy Consuming Equipment. This Thesis Presents Analysis Of Energy Utilization And Energy Saving Opportunities In The Factory. The Study Is Based On The Realization That Enormous Potential Exists For Energy Saving Improvements In The Existing Energy Consuming Industrial Equipment. Up On The Actual Measured Data, The Two Hot Water Boiler Performance Assessment Is Carried Out By Considering Different Heat Losses. The Typical Boiler Efficiency Is Of 81% And 80% For Boiler-1 And Boiler-2. The Remaining Part Of The Energy Is Lost In Different Forms Of Wasted Heat. As Per The Analysis, The Major Heat Loss Is Occurred Due To Dry Exhaust Flue Gas. Additionally, Water Chiller, Air Compressor, Driving Electrical Motors, Pumps And Lighting System Equipments Energy Utilization And Annual Saving Opportunities Are Determined In This Study. In Pasta And Macaroni Production Process The Dryer Section Of The Production Process Consumes Huge Amount Of Thermal Energy To Evaporate Unnecessary Moisture From The Surface As Well As The Inner Part Of The Product. This Study Investigate That About 6,885tj/Year, 9,539.6tj/Year And 10,132.5tj/Year Energy Is Consumed Annually By Dryer-2, Dryer-3 And Dryer-4 Respectively. After Detailed Analysis, The Thermal Efficiencies Of Typical Dryers Are To Be Observed 75.3%, 80% And 73.1% For Dryer-2, Dryer-3 And Dryer-4 Respectively. In General, After Detailed Thermal Energy Consumption Was Conducted, 26%, 36% And 38% Of Total Annual Thermal Energy Of 7,376,971 Kwh Was Consumed By Plant-2, Plant-3 And Plant-4 Respectively. It Is Also Observed From The Analysis That The Driving Motors Of Plant-2, Plant-3 And Plant-4 Are Consuming About 20%, 25% And 8% Of The Total 20,480,377kwh Annual Electrical Energy Consumed By The Industry Respectively And About 47% Of The Total Electrical Energy Is Consumed By The Pump Motor, Air Compressor, And Chiller And Lighting Systems In The Factory. The Investigation Has Revealed That The Industry Has Significant Energy Saving Potential. Different Energy Saving Measures Are Adopted And It Is Found That The Industry Can Save 262,681.4kwh Per Annum From Using High Efficient Motors Rather Than Normal Motors, 782.6 Gj/Year Heat Energy Recovered From Dry Exhaust Flue Gas To Preheat Combustion Air And 1221 Gj/Year From Excess Combustion Air Controlling By Using Oxygen Analyzer. This Implies The Total Annual Bill Saving Potential Of The Factory Will Be About 1,676,872 Etb Per Year.
