Assignment No 2 Energy Management 1. What are the principles of energy management? List any four important factors involved in deciding final cost of purchased electricity. 2. What do you mean by energy audit? Give any four bench marking parameters followed in equipment/utility related in Industries. 3. What are the base line data that an audit team should collect while conducting detailed energy audit? 4. What is the objective of energy management? What are fuel substitution and list one example of fuel substitution? 5. Give any four bench marking parameters followed in equipment/utility related in Industries. How do you classify energy conservation measures? 6. Briefly explain with examples on fuel and energy substitution 7. Distinguish between ‘preliminary energy audit’ and ‘detailed energy audit’? 8. Give a typical energy audit reporting format. 9. Write down the steps involved in ‘Energy management Strategy’? (EA) 10. List down Identification of Energy Conservation Opportunities. 11. A plant is using 6 ton/day of coal in a boiler to generate steam at 72% boiler efficiency. The gross calorific value of coal is 3300 kCal/kg. The cost of coal is Rs. 4200/ton . The plant substitutes coal with agro-residue , as a boiler fuel, which has a gross calorific value of 3100 kCal /kg and costs Rs. 1800/ton. The boiler efficiency reduces to 68%. Calculate the annual cost savings for 300 days of operation with agro residue as fuel. 12. The integrated paper plant has produced 119366 MT of paper during the year 2012-13. The management has implemented various energy conservation measures as part of PAT scheme and reduced the specific energy consumption from 53 GJ/ tonne of product to 50 GJ/tonne of product. The actual production during the assessment year (2014-15) is 124141 MT. Calculate the plant energy performance and state your inference.
