Design of Steam Dump Device for Steam Surface Condensers
Few years ago, “condenser steam dumps” or more appropriately “steam turbine bypass systems” were out of line
items, only occasionally supplied. These days, steam turbine bypass systems are required for most new condensers in power
projects. Due to potential for serious damage to the condenser and its internals by poor quality steam dump, it is essential
that proper design principles be incorporated at the earliest stage of design. With space becoming imperative for the
condensers, it is important that guidelines for the design and operation of steam turbine bypass system especially steam
dumps be discussed. This paper examines factors affecting the design of steam dump device in turbine bypass system and
gives methodology to be used to design steam dump device for surface condensers.
