Abstract
Project evaluation necessarily requires
performance estimates over the project life
cycle. In contrast to new and clean conditions,
extended life performance inherently
introduces additional complexity and variability
in developing such estimates, due
to changing operating environment, maintenance
policies, operating procedures,
equipment availabilities, etc. This paper
discusses the general nature, and the thermal
interaction of power plant components
as individual equipment degradation occurs,
describing overall plant performance trends
and quantifying typical ranges for a given
application. A specific cogeneration example
will be discussed and the economic
effects of life cycle performance with
various plant design assumptions will be
shown. Design considerations to minimize
long term performance degradation will also
be described.
