How to Find the Dryness Fraction

05/24/2011 8:50 AM

In boiler we are getting steam at .85 dryness fraction but near curing press what will be the dryness fraction and is there any steam line loss and how to find the latent heat when it condensing inside the bladder.

The dryness fraction at the load depends upon the number and effectiveness of condensate traps between the boiler and the load.

The latent heat of steam can be found from Steam Tables given knowledge of the pressure and temperature, though if the steam is not superheated then it is only necessary to know one of these.
