Boiler – Fundamentals and Best Practices

Steam Production From steam tables we can see that the total heat of steam does not vary a great deal as the boiler pressure increase The boiling point (b.p.) increases as the pressure increases Thus the sensible heat increases as the pressure increases, and the latent heat decreases Boiler pressures are expressed in psia, psig, bar, kg/cm2
