Abstract
This paper discusses how to decide whether to
generate any or all of a plant's power, or to use
power, purchased or self-generated, to move heat
or do work. The analysis can be conducted by
developing energy composite curves. Using the
information derived, this paper will show how to
examine the potential application of heat exchange
or heat engines using fuel to produce power and
lower grade heat, or the application of heat pumps
using power and low grade heat to produce higher
grade heat.
