Overview

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

Key Formulas

Steam Quality

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

Mass fraction of vapor in two-phase mixture.

Enthalpy of Wet Steam

h=hf+xhfgh = h_f + x \cdot h_{fg}

Specific enthalpy of wet steam.

Flash Steam

mflash=mliquidhfhf2hfg2m_{flash} = m_{liquid} \frac{h_f - h_{f2}}{h_{fg2}}

Steam generated when condensate flashes to lower pressure.

Condensate Load

mc=Qhfgm_c = \frac{Q}{h_{fg}}

Condensate generated by heat transfer.
