Power stations that were originally designed for base load applications are now increasingly being
asked to operate on a two shift, stop/start regime; this is more commonly known in the industry as
dual shifting. The multiple start/stops that these stations are now experiencing is in some instances
causing an increase of operational issues due to the to the constantly changing process
parameters. For example dual shift stations will experience additional thermal stress in the
headers, drums, high temperature piping, valves plus the auxiliary equipment leading to additional
wear and tear of their systems and component parts. This is due to the more frequent use of the
plant at severe service conditions. The consequences of the change in plant operation...
This paper highlights the issue of attemporators in dual shifting power stations.
