Overview

Engineering reference data for Feedwater Temperature Steam Boiler Rating in steam condensate.

$x = \frac{m_v}{m_{total}}$

Mass fraction of vapor in two-phase mixture.

$h = h_f + x \cdot h_{fg}$

Specific enthalpy of wet steam.

$m_{flash} = m_{liquid} \frac{h_f - h_{f2}}{h_{fg2}}$

Steam generated when condensate flashes to lower pressure.

$m_c = \frac{Q}{h_{fg}}$

Condensate generated by heat transfer.
