Air-cooled condensers and air-cooled condenser streets for condensing exhaust steam from a turbine are disclosed. An example air-cooled condenser street includes one or more rows of V-shaped heat exchangers. Each row includes a main steam manifold to introduce exhaust steam into tube bundles that are placed in an inclined position such that condensate formed in the bundles flows back by gravitation to the main steam manifold. Top steam manifolds are connected to the upper end of respectively each of the tube bundles of the air-cooled condenser street. The series of parallel top steam manifolds are forming a support assembly for supporting one or more fan decks. The fan decks support a plurality of fans to induce an air draft in the V-shaped heat exchangers.

A pumping and trapping device is provided. The pumping and trapping device removes condensate from a heat exchanger even when upstream pressure in the device is lesser than the downstream pressure. The device includes a float operated mechanical linkage. The float is displaceable with respect to condensate level within a vessel of the device. The mechanical linkage is configured to selectively operate a steam inlet port and a steam outlet port configured on the vessel, thereby removing condensate accumulated within the vessel.

A solar aided coal-fired power generation system participating in primary frequency regulation and a control method thereof propose a system configuration with two regulation schemes by coupling medium-low-temperature solar collectors and a coal-fired generation unit. The two regulation schemes are a high-pressure feedwater bypass scheme and a low-pressure condensate bypass scheme. The present invention formulates a primary frequency regulation control logic, so as to efficiently and accurately participate in the primary frequency regulation, thereby keeping the power grid frequency rapidly stable. The present invention also formulates a working fluid outlet temperature control logic for the solar aided coal-fired thermal system, which adjusts a heat exchange working fluid flow of the solar collectors to ensure that the temperature in each section is stable during the primary frequency regulation. The present invention uses operation matching of the turbine system and the solar collectors to improve effectiveness of the primary frequency regulation. With rational utilization of different temperature zones of different heat collectors, irreversibility is reduced, and economic efficiency of various thermal system adjustment schemes is further improved. As a result, operation flexibility of the transient process of a supplementary power generation unit can be greatly improved.

Large scale field erected air cooled industrial steam condenser having heat exchanger bundles constructed with an integral secondary section positioned in the center of the heat exchanger, flanked by identical primary condenser sections. A bottom bonnet runs along the bottom length of the heat exchanger bundle, connected to the bottom side of the bottom tube sheet, for delivering steam to the bottom end of the primary condenser tubes 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 flow into the top bonnet from the primary condenser tubes and flow toward the center of the heat exchanger bundle where they enter the top of the secondary condenser section tubes. Non-condensables and condensate formed in the secondary section tubes enter a secondary bottom bonnet inside the primary bottom bonnet and are withdrawn from the secondary bottom bonnet via outlet nozzle. Each cell of the ACC is fed by a single riser which delivers its steam to an upper steam distribution manifold suspended from and directly below the bundle support framework.

A panel assembly (such as for an internal cabin of an aircraft) includes at least one liquid flow path formed on at least one surface through surface treatment. The at least one liquid flow path is formed in relation to at least one bank on the at least one surface. The at least one liquid flow path is configured to divert liquid to a desired location.

A volatilized substance is condensed using a vapor-liquid interface. The volatilized substance is diffused into a condenser vessel containing a cooling liquid via a diffusion device. When the volatilized substance comes into contact with the cooling liquid it is condensed. The large vapor-liquid surface area created by the diffusion device enhances the rate of condensation. The cooling liquid is circulated through a heat exchanger to remove heat introduced by the condensing vapor. The temperatures of the cooling liquid leaving and entering the condenser vessel are monitored.

A method for removing condensate from a steam line during a cold startup is provided, including introducing a dip tube in a substantially vertical orientation within a substantially vertical section of a steam line, wherein the dip tube includes a proximal end and a distil end, immersing the distil end within a volume of condensate, connecting the proximal end to a removal conduit external to the steam line, and removing at least a portion of the condensate through the removal conduit.

Provided is an apparatus for extracting water from a condenser to the outside for water quality analysis. The apparatus includes an insertion pipe inserted into a condenser, a screw thrust portion including a rotating shaft inserted into the insertion pipe, a screw coupled to one end of the rotating shaft, and a screw thrust portion comprising a power providing portion configured to transmit power to the rotating shaft, and an exhaust pipe provided in the insertion pipe to introduce the water to flow to the outside of the condenser when the water contained in the condenser flows toward a rear side of the screw according to a rotation of the screw.
