The characteristics of heat transfer and pressure drop of the steam condensation in plate evaporator were analyzed based on experiment platform of the steam condensation test. The properties of heat transfer of steam condensation in herringbone plate evaporator were predicted by using the two-phase flow condensation model. A correlation of steam condensation heat transfer coefficient in herringbone plate evaporator was fitted by the multiple linear regression analysis method. Pressure drop per unit length along herringbone plate increased with the velocity of steam. Several pressure drop models of steam condensation in herringbone plate evaporator were compared. The experimental correlation between steam condensation friction factor and the equivalent Reynolds number was derived.
