Country Industry EE&C Activities Food Industry 1. Installation of economizers on LP boilers 2. Waste heat recovery from hot water boilers (Edible Oil Refinery) 3. Process oil cooling by cold feed water 4. Condensate collection system Total fuel saving = 116,703GJ/y (=Approx. 2,920kL/y) Malaysia Iron/Steel Industry 1. 2-stage recuperator (Recovery of flue gas temp.) 2. Air compressor change, from piston type to Capacity: screw type: Power saving = 45% EAF: 700kt/y, 3. VSD for rolling mill cooling water pump process Mill: 550kt/y Power saving = 25% compared to throttle valve Power saving = 1.7%, Fuel saving = 13.7% Total cost reduction = 3% Chemical Industry Change the 200RT refrigeration system from a vapor RI Chemical Corp. compression type to a vapor absorption type, wherever there is waste heat and a need for chilled water. Effect on productivity: +3.6% Philippines Iron/Steel Industry Introduction of outline of Philippines steel industry (By DOE) and 2005 Don Emilio Abello EE Awards [Rolling Mill Co. saved 580kL/y of fuel oil by heat recovery from the furnace, etc. and Steel sheet coating Co. saved 107kL/y of oil] Porcelain Industry Significant percentage improvement after 2004 follow up. (By MOI) Similar presentation at last Summary-Workshop Brick Industry Energy audit at brick factory: Fuel saving = 3%. Vietnam (By MOI) Power saving = 13% by insulation strengthening, etc. Energy Audits at 12 Main measures identified by audit: industrial factories VSD, boiler improvements, condensate collection (By Institute of system, maintenance method, compressed air Energy) system, etc. Saving: Fuel = 0~38%.
