A steam power plant with a low-pressure turbine is suggested with a second low-pressure turbine on a separated shaft line including a separate generator. The second low-pressure turbine is connected to an additional condensing system without cooling water consumption, thus allowing to maintain the power output at a high level, even if the main condensing system has a reduced capacity due to cooling water restrictions.

A heat engine system and a method for cooling a fluid stream in thermal communication with the heat engine system are provided. The heat engine system may include a working fluid circuit configured to flow a working fluid therethrough, and a cooling circuit in fluid communication with the working fluid circuit and configured to flow the working fluid therethrough. The cooling circuit may include an evaporator in fluid communication with the working fluid circuit and configured to be in fluid communication with the fluid stream. The evaporator may be further configured to receive a second portion of the working fluid from the working fluid circuit and to transfer thermal energy from the fluid stream to the second portion of the working fluid.

This low-pressure condenser is provided with: a pressure bulkhead which partitions the inside of the container into an upper space and a lower space; a heat transfer tube which is arranged in the upper space; and a reheater which is arranged in the lower space and which, by means of high-temperature steam flowing from the outside into the lower space, heats water which condenses in the upper space and flows into the lower space. The reheater includes multiple partition members, a receiving plate which receives water flowing downward via the partition members, and a dam which is connected to the outer peripheral edge of the receiving plate. The lower ends of the multiple partition members are below the upper end of the dam.

An evaporative condenser radiating module for steam exhaust of a steam turbine comprises tube bundles and steam-water separating chambers. A steam-water separating chamber (4) between a section A and a section B, a section A downflow cooling section tube bundle (3), a section B downflow cooling section tube bundle (5), and a counter flow cooling section tube bundle (8) are disposes at the left side of a central steam-water separating chamber (7). An upper sealed space (10) of the steam-water separating chamber (4) between the section A and the section B is in communication with the central steam-water separating chamber (7) through the counter flow cooling section tube bundle (8). A lower sealed space of the steam-water separating chamber (4) between the section A and the section B is in communication with the central steam-water separating chamber (7) through the section B downflow cooling section tube bundle (5). A sealed section A steam entering chamber (2) is arranged on the left side of the steam-water separating chamber (4) between the section A and the section B. The section A downflow cooling section tube bundle (3) is arranged between the section A steam entering chamber (2) and the lower sealed space of the steam-water separating chamber (4) between the section A and the section B. The right side of the central steam-water separating chamber (7) is provided with tube bundles and steam-water separating chambers totally structurally identical with those arranged on the left side of the central steam-water separating chamber (7).

Large scale field erected air cooled industrial steam condenser having heat exchanger panels with primary and secondary condenser sections, in which the secondary condenser section comprises 10% or less of the total heat exchanger, and in which the tubes of the primary condenser sections have narrowed outlet orifices having an area that is 50% or less than the cross-sectional area of a corresponding tube. The invention permits the reduction of secondary condenser tubes while reducing the outlet header pressure sufficiently to minimize backflow, sweep non-condensables and prevent the formation of dead zones.

Large scale field erected air cooled industrial steam condenser having heat exchanger panels independently loaded into and supported in a heat exchange frame section. A bottom bonnet runs along the bottom length of each heat exchanger panel for delivering steam to the bottom end of condenser tubes in the heat exchange panel and for receiving condensate formed in those same tubes. The tops of the tubes are connected to a top bonnet. Uncondensed steam and non-condensables are drawn into the top bonnet from the condenser tubes. A steam distribution manifold is suspended from the heat exchange section frame perpendicular to the longitudinal axis of the heat exchange panels and beneath a center point of the heat exchange panels and delivers steam to each heat exchange panel via a single steam inlet located at a center point of each bottom bonnet.
