A good approach point is between 15°F - 30°F.• This temperature will guarantee that no steaming will occur in the economizer section.• It is not always possible to achieve an approach point in this zone.• If the saturation temperature is too high, achieving an approach temperature in this zone will lead to a stack outlet temperature well below the dew point, resulting in use of special steels to avoid corrosion.w w w . e u r o b o i l e r s . c o mw w w . g a r i o n i n a v a l . c o m• The pinch point is the difference between the saturation temperature and the EVAP exit temperature• It is desirable to make the pinch point as small as possible without making the cost of the EVAP astronomicaltRansfeR suRface aReapincH is ussed in siZinG Heatof tHe evappincH is ussed in siZinG Heat tRansfeR suRface aRea of tHe evappRocess desiGn consideRationpRocess desiGn consideRationSYSTEM DRAFT LOSSHigher the permissible draft loss. Lower is the capital cost and GT output.Restriction on firing temperature due to construction. All operating modes to satisfy this limit.FIRING TEMPERATURE LIMITATIONPINCH POINTLower Pinch means higher heat recovery and higher capital cost.Lower approach means higher heat recovery and higher capital cost. Lower approach means higher steaming potential under upset/partial load conditions.APPROACH TEMPERATUREDifficult for unfired units as heat source is uncontrolled. Some what better for supplementary fired units as heat imput is partially controllable.APPROACH TEMPERATURE / APPROACH TEMPERATUREVery narrow for unfired units. Comparatively wider for fired units as EXH.Gas reheat temperature has a considerable impact on steam temp.STEAM TEMPERATURE CONTROL RANGEw w w . e u r o b o i l e r s . c o mHigher operating modes to suit operation.
