MULTITUBULAR HEAT EXCHANGER USED IN A POWER PLANT ABSTRACT OF THE DISCLOSURE A multitubular heat exchanger for use in a power plant is provided with a bundle of U-shaped heat transfer tubes and a vent tube. The vent tube is located between an upper portion and a lower portion of the heat transfer tubes. A steam flow guide plate is located above one or more holes of the vent tube and below the upper portion of the heat transfer tubes. This steam flow guide plate obstructs downward steam flow from the upper portion of the bundle toward the vent tube, while causing an upward flow towards such tube, and thus facilitates collection of the gas.
