Condenser for water supply steam turbine of 300MW unit

The utility model relates to condensers, in particular to a condenser for a water supply steam turbine of a 300MW unit. The condenser aims to solve the problems that an existing condenser for the water supply steam turbine of the 300MW unit is complex in structure and low in work efficiency, thereby seriously affecting the operating efficiency of the water supply steam turbine of the 300MW unit. According to the condenser, two tube plates are arranged in parallel side by side in a condenser shell; multiple cooling water pipes are arranged in parallel side by side between the two tube plates; each air cooling zone is separated from a main condensing zone located on the same side as the air cooling zone through an air cooling zone baffle; a cooling water outlet water chamber is formed by the inner side end face of the other end of the condenser shell, the inner side wall of the condenser shell and the tube plate in the other end of the condenser shell; the upper surface of the condenser shell is provided with a
