Are there any other implications of steam supplied to heat exchangers not having a few degrees of superheat other than the fact that most heat is exchanged due to latent heat of vapourisation?
besides to value, steam jackets are utilized in lots of cases the place you do no longer desire to administration the temperature precisely yet basically desire issues warm. yet another application for jackets is the area the place the cloth being heated can plug an excellent-unfold warmth exchanger's tubes.
If you have steam with a few degrees of superheat you are less likely to have low quality steam in the exchanger. That is the real problem is low quality steam which doesn't have it's full latent heat and therefore requires more steam to deliver the same quantity of heat to the exchanger.
Lower quality steam , if appreciable would mean less cooling water needed. If this was known in the design, the tube sizes might be reduced to keep the water velocity in range. Superheat would be just a small part of the condensing load and you do want the steam leaving a turbine to be dry to prevent blade erosion.
