FIELD OF INVENTION
The invention generally relates to a steam condensation system and more particularly to a power plant steam condensation system.
BACKGROUND
A conventional power plant typically comprises of a main feed pump to pump liquid to a boiler. The boiler is the steam generation unit in the power plant. The boiler converts the liquid into a high pressure and high temperature steam. The high pressure and high temperature steam enters into a turbine where the steam spins the turbine blades and drives an electric generator. The high pressure and high temperature steam leaves the turbine as a low pressure and low .temperature steam. The low pressure and low temperature steam enters a cooling tower and a \. condenser where the steam condenses into liquid. This liquid is pumped to the boiler again by the main feed pump and the cycle goes on.
In the present power plant systems, the cooling of the steam takes place in the cooling tower and the condenser. The major drawback of using the cooling towers and condensers is that they consume power for a condensation process which reduces the overall efficiency of the power plant.
The present invention is directed to overcoming one or more of the problems as set forth above.
SUMMARY OF THE INVENTION

According to an exemplary embodiment of the invention, a power plant steam condensation system is disclosed. The power plant steam condensation system may comprise of a closed condensing well. The condensing well may be filled with water up to a predefined level. The condensing well may have a spray nozzle for a steam to discharge in the condensing well. The condensing well may also include a tube for the steam to flow from an inlet port of the condensing well to the spray nozzle. According to an embodiment, the steam may atomize at the spray nozzle discharge. When the steam discharge from the spray nozzle and may come in contact with the water in the condensing well, the steam may dissolve and condense into the water. The condensed water may be pumped to a boiler through an outlet port provided in the condensing well.

DETAILED DESCRIPTION OF DRAWINGS

The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of exemplary embodiments. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.
Figure I illustrates a front view of an exemplary power plant steam condensation system (100) according to an embodiment of the invention. The power plant steam condensation system . (100) may comprise of a closed condensing well (102). The condensing well (102) condenses steam into water. According to an embodiment, the top surface of the condensing well (102) may be above ground level. The top surface of the condensing well (102) may be provided with manhole to perform service operations in the condensing well (102).. A makeup feed pump (104) may be provided between the condensing well (102) and the .boiler (106) to pump the water from the condensing well (102) to the boiler (106).The makeup feed pump (104) may be operable when the pressure is not sufficient for the water to flow from the condensing well (102) to the boiler (106). The boiler (104) converts the water into a high pressure and high temperature steam. The steam may flow in a turbine (108) where it may spin the turbine (108) blades and drive a generator (110). The turbine (108) may convert the high pressure and high temperature steam into a low pressure and low temperature steam. The low pressure and low temperature steam may flow into the condensing well (102). According to an embodiment of the invention, the power plant steam condensation system (100) may include more than one condensing well (102). The extra condensing well (102) may be usable only when the temperature and pressure in the running condensing well (102) may reach up to a predefined

temperature and pressure. The switching among the condensing wells (102) may be achieved through the different ports of each condensing well.
Figure 2 illustrates a front view of the condensing well (102) according to an exemplary embodiment of the invention. The condensing well (102) may be filled with water up to a predefined level. According to an embodiment, the condensing well (102) may be filled with water up to 75% of the condensing well (102) volume. The remaining 25% of the condensing well may remain with air. The condensing well (102) may, include an inlet port (112) for the steam to enter into the condensing well (102) from the turbine (108) and an outlet port (118) for the water to flow out of the condensing well (102) to the boiler (106). The inlet port (112) may be. provided at the top of the condensing well (102) and the outlet port (118) may be provided at the bottom of the condensing well (102). The condensing well (102) may have a tube (116) connecting the inlet port (112) and a spray nozzle (114). According to an embodiment, the tube (116) may be helical in shape. The steam may flow in the tube (116) to the spray nozzle (114). The tube (116) and the spray nozzle (114>ma'y be arranged in such a way that the spray nozzle (114) may be placed at the bottom of the condensing well. (102). According to an embodiment, the spray nozzle (t 1.4) may be immersed in the water in the condensing well (102). The spray nozzle (114) may atomize the steam discharging from the spray nozzle (114) to the condensing well (112). The steam may dissolve and condense into water when the steam comes in contact with the water in the condensing well (102). The outlet port (118) provided in the condensing well (102) may be kept closed. The closed outlet port may increase the pressure and temperature of the condensing well (102). When sufficient pressure and temperature is generated in the condensing well (102), the outlet port (118) may be opened for the water to flow out of the condensing well (102). The condensed water may flow from the condensing well (102) to the boiler when the outlet port is open. According to

the embodiment, the makeup feed pump (104) may be used only when the pressure is not sufficient for water to flow from condensing well (102) to the boiler (106). According to another embodiment, the makeup feed pump (102) may also be eliminated from the power plant steam condensation system (100) if sufficient pressure is generated in the condensing well (102) for condensed water to flow to the boiler (106).
