Heat transfer numerical model of a corrugated plate condenser was established. The plate condenser was used in organic Rankine cycle （ORC） power generation system and R245fa was chosen as working medium for 90 ℃ flushing water of blast furnace slag. Then the experimental platform was built to verify the correctness of the numerical model. With the help of the numerical model， the effects of the overheat degree， wall supercooling and vapour dryness on heat transfer coefficient， pressure drop and comprehensive heat transfer performance were discussed. And the heat transfer correlation formula for the plate condenser with R245fa as working medium was fitted. According to the volume fraction of condensate phase along the plate length， the possibility of intermediate drain of the condenser was discussed， and the suitable intermediate drain range along the plate length was given for the volume fraction of condensate phase.
