20080213102 | Fluid pump having multiple outlets for exhausting fluids having different fluid flow characteristics - A pump configured to receive fluids through an inlet and direct those fluids in two directions through two or more fluid discharge outlets, wherein the fluids are discharged with different fluid characteristics, such as different pressures or flow rates. In one embodiment, the pump may include first and second pumping chambers for pumping fluids from the pump with different pressures or flow rates, or both, eliminating the need for two pumps. The fluid may be exhausted from the pump through a first fluid discharge outlet and a second fluid discharge outlet of the pump. | 09-04-2008 |
20090241544 | Method of Increasing Service Interval Periods in a Steam Turbine - A method of increasing service interval periods in a steam turbine by neutralizing sodium hydroxide in contaminated steam in a high temperature and a high pressure portion of a steam turbine by placing a protective covering over at least a portion of each of the bolts of a nozzle block assembly. The protective covering neutralizes contaminants in contaminated steam to reduce stress cracking of the bolts during steam turbine operation, and thus extend the useful life of the bolts and reduce the need for service work to repair or replace damaged bolts. | 10-01-2009 |
20090266076 | Condensate Polisher Circuit - A power generating system including a working fluid circuit. The power generating system includes a condenser system in the working fluid circuit and a condensate polisher circuit. The condenser system receives a working fluid that includes steam or a combination of water and steam and condenses at least a portion of the working fluid into a condensate. The condensate has a temperature above a predetermined upper operating temperature. The condensate polisher circuit is branched off from the working fluid circuit and receives and treats said condensate from the working fluid circuit and returns treated condensate to the working fluid circuit. The condensate polisher circuit includes a heat exchanger that reduces the temperature of the condensate at least to the upper operating temperature and a condensate polisher that removes contaminants from the condensate to bring the condensate to a predetermined purity. | 10-29-2009 |
20100199670 | Power Generation Plant Having Inert Gas Deaerator and Associated Methods - A power generation plant includes a steam turbine and an electrical generator driven thereby. A condenser is downstream from the steam turbine. Moreover, the power generation plant includes a steam source and an inert gas source. A deaerator downstream from the condenser and is operable to perform deaeration using the inert gas source and is also selectively operable to perform deaeration using the steam source. | 08-12-2010 |
20100199671 | Deaerator Apparatus in a Superatmospheric Condenser System - A power generating system comprises a condenser and a deaerator apparatus. The condenser condenses a working fluid into a condensate and operates at an internal pressure above ambient pressure during a normal operating mode. The deaerator apparatus uses steam to remove contaminants from the condensate to bring the condensate to a desirable purity. The deaerator apparatus is deactivated during a typical operating state of the power generating system such that the condensate bypasses the deaerator apparatus. The deaerator apparatus is activated during a non-typical operating state of the power generating system such that the condensate passes into the deaerator apparatus wherein contaminants can be removed from the condensate. The typical operating state of the power generating system occurs when the condensate comprises a desirable purity and the non-typical operating state of the power generating system occurs when the condensate comprises an undesirable purity. | 08-12-2010 |
20100199672 | Condenser System - A method of substantially preventing contaminants from entering a condenser adapted for use within a steam generating system. A condenser is provided. Steam or a combination of water and steam is passed into the condenser, the condenser operating in a normal mode a pressure in a control area is equal to or greater than a predefined pressure and in a non-normal mode if the pressure in the control area is less than the predefined pressure. An inert gas is injected into the condenser if a pressure in the control area is less than a holding pressure, the holding pressure being equal to or greater than the predefined pressure. | 08-12-2010 |
20100257860 | Air Vent in Main Steam Duct of Steam Turbine - A power plant including a steam turbine, and a steam turbine exhaust duct configured to deliver uncontaminated fluid from the steam turbine to downstream components of the power plant. The steam turbine exhaust duct includes a steam turbine exhaust duct isolation valve selectively configured to prevent fluid communication between the steam turbine exhaust duct and the downstream components of the power plant, and a steam turbine exhaust duct vent with a steam turbine exhaust duct vent valve. The steam turbine exhaust duct vent is configured to deliver contaminated fluid from the steam turbine exhaust duct to a fluid sink upon opening of the exhaust duct vent valve. | 10-14-2010 |
