Practical Energy Efficiency Optimization

Appendix A: Exercises

Overview

Chapter 1. Industrial Energy Management

  1. What are the average energy consumption patterns of developed and developing nations?

  2. What strategies may be adopted to increase the GNP and GDP of a country? What does the energy cost have to do with these national productivity parameters? Explain with suitable data.

  3. How can we apply Pareto's model to national-level energy consumption and economic indices? Explain with suitable data. What are the national-level strategies that may be evaluated to minimize energy cost?

  4. Explain this statement: "Energy consumers are environmental polluters also, besides being economic giants."

  5. Develop a national-level energy resource model that will minimize energy cost and pollution.

  6. What technological improvements/modifications may be applied to minimize energy losses and maximize energy efficiency? Explain with examples.

  7. What is an energy cost model? In a complex industry, how does energy costing help in energy cost minimization drive? Explain with suitable examples.

  8. What is a profit planning cycle? How can that be developed for a complex industry?

  9. "In petroleum refining, energy consumption is determined by hardware selection alone." Do you agree with this statement? If so, please explain with suitable examples of a refinery of your choice.

Chapter 2. Optimization Basics

  1. What is meant by optimization? What are the prerequisites for developing an optimization model? Explain this concept with the help of an industrial example and a national-level example.

  2. Four boilers are in operation in a power plant, each producing 300 t/h of steam, fed to a set of four turbines, each with 30 MW capacity...
