After finishing this lesson, you will be able to list several key operating parameters that affect efficiency. You will also be able to describe in your own words problems that can prevent key operating parameters from being operated at optimum level. You will be able to calculate the approximate extra fuel cost associated with operating a key performance parameter off design value. • Describe net unit heat rate in your own words • List several key operating parameters that affect net unit heat rate • Describe in your own words problems that can prevent key operating parameters from being operated at optimum level • Given industry average data, calculate the approximate effect on net unit heat rate when a key operating parameter is operated off the design value • Given appropriate supporting data, calculate the approximate extra fuel cost associated with operating a key performance parameter off of design value
