ABSTRACT:
A crossover conduit structure for transmitting steam from a first to a second turbine section having a conduit disposed between an exhaust portion of the first turbine section and an inlet portion of the second turbine section and a moisture removal structure situated downstream from the inlet portion axially along the conduit. The conduit's longitudinal axis is arranged generally perpendicular to the inlet portion's longitudinal axis with the moisture removal structure being disposed axially downstream from the inlet portion in the direction of the steam flow through the crossover conduit. The moisture removal structure includes a tapered transition section having first and second ends which are respectively disposed relatively adjacent and remote from the inlet portion, a pipe attached to the second end of the tapered portion, and an orifice or other means for regulating water and steam flow through the condensate pipe. The first end of the tapered transition section has an inside diameter at least as large as the crossover conduit while the second end has an inside diameter less than the first end. The orifice or other flow regulating means controls water and steam flow through the water transmitting means or pipe so as to effectively limit the steam flow quantity passing through the pipe in bypassing relationship with the second turbine section.
