Abstract [en]

Iggesund Paperboard in Workington have had problems with unstable heat recoveryon the condensate from dryers on the board machine. The instability in combinationof unreliable heat availability has led to dependence on heat from fresh steam. Thisproject investigates the current system performance and evaluates three suggested systemchanges. Evaluations are done with a model of the system created in Simulink. Byredirecting cold water stream from condenser M216 to shower water tank (S060) freshsteam usage can be reduced from current 25% to 14% of production time. With additionalheat from oce room heating the fresh steam usage can be reduced to 3% of productiontime. With a tap o from M216 to cooling water tank (S050) and a temperature controlthe instability is avoided.
