Claims15
A system for introducing bypass steam to a cylindrical steam surface condenser, the condenser having condensing tubes and a condenser shell, the condenser shell having a circumference and an opening in the circumference, the system comprising a hat-like steam admission chamber external to the circumference of the condenser shell, the admission chamber adapted to fit the opening in the condenser shell, the admission chamber including a header having orifices arranged within the admission chamber, the system also comprising dummy rods or tubes arranged within the circumference of the condenser between the condensing tubes and the opening.
A method of introducing bypass steam to a cylindrical steam surface condenser having a condenser shell and condensing tubes comprising
- providing an opening in the condenser shell and a hat-like steam admission chamber external to the circumference of the condenser shell;
- securing the admission chamber to the opening in the condenser shell, the admission chamber including a header having orifices arranged within the admission chamber;
- and
- providing dummy rods or tubes arranged within the circumference of the condenser between the condensing tubes and the opening to buffer the impact of the bypass steam released through the orifices prior to the bypass steam reaching the condensing tubes.
