Regenerative Boiler Feedwater Heater Economics
Abstract
The basic Rankine Vapor Cycle has been
repeatedly modified to improve efficiency.
Always, the objective is to produce more power
from constant fuel, or constant power from less
fuel. Pressures and temperatures have been driven
upward; vacuum has approached atmospheric limits.
Multiple stages of regenerative feed preheat and
steam reheat are normal in utility stations.
With renewed emphasis on cogeneration, utility
station concepts for heat power cycle efficiency
improvement are becoming more applicable to
industrial steam systems. Regenerative
feedwater heating is one such opportunity. In
these systems, the question often is: do we
increase from one stage of heating (usually the
deaerator) to two? Or more? The concepts are
discussed in this paper, and the use of system
computer modeling is demonstrated, to determine
the technical and economic practicality of adding
a heater stage.
