Abstract: A power generation system (11) and method of operating such a system (11) including a steam turbine (14). In one embodiment a HRSG (20) includes an evaporator (127) coupled to receive condensate from the steam turbine (14), and a superheater (132) coupled to receive output from the evaporator (127). The HRSG (20) generates steam with thermal energy received from a combustion turbine (28). A flash tank (9) receives water heated in the HRSG (20), outputs a first portion of the water as steam, and outputs a second portion of the water as liquid. A flow line (134) passes steam (51) from the flash tank (9) to a combustion chamber (26) in the combustion turbine (28) to provide power augmentation.

Abstract: A method of evaluating a power plant having a design life based on operating the plant within an allowable chemical exposure range includes accumulating a history of a chemical exposure of a steam generating portion of the power plant. The method also includes determining a remaining life of the plant based on the history of the chemical exposure and assuming continued operation of the plant within the allowable chemical exposure range.

Abstract: 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.

Abstract: 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.

Abstract: A combustion turbine power plant (10) incorporating a water recovery apparatus (34). A sulfur stripper portion of the water recovery apparatus uses water (56) to remove suffer from the exhaust (20) of the combustion turbine (12) and to produce a reasonably high concentration of sulfuric acid for subsequent recovery of the sulfur. A water stripper portion (36) of the water recovery apparatus uses an aqueous solution of a desiccant (74) to absorb water from the exhaust gas. The wet desiccant may then be heated or exposed to a sub-atmospheric pressure in a regenerator (102) to recover the water. A sub-atmospheric regenerator may be maintained at a sufficiently high temperature by transferring waste heat from the exhaust gas. The resulting moisture content of the exhaust gas may be below that which can be achieved using traditional cooling heat exchangers.

Abstract: The system of the present invention uses the importance of a piece of malfunctioning equipment, the severity and the confidence level in a diagnosis to determine repair priority of the equipment by obtaining the product (46) of the confidence level (CF), importance (IMP) and severity (SEV). The these variables are determined by expert system rules. The severity is the reciprocal (88) of the time to failure. The importance (44) is the cost to repair the maximum damage when the malfunction continues. A malfunction can affect several pieces of equipment in combination, the severity and importance associated with each piece is combined (70) with the confidence and used to determine the repair priority. When the diagnosis of a malfunction is by malfunctioning sensors, the expected equipment life (40) and the availability (86) of sensors that provide a partial backup are considered in prioritizing sensor as well as equipment repair. When a primary piece of equipment is backed up (100), the effect of both pieces of equipment failing (106) is considered in prioritizing the repair. The system ranks the repair of all possible malfunctions on a common scale. The system gives a complete repair priority picture and allows the cost effectiveness to be maximized.

Abstract: A method for automatically generating recommended actions in response to a diagnosis uses a list ordered by impact of the actions. The list is evaluated using required evidence which must be supported by data and assumed evidence which must not be contradicted by the data. The method is applied to the diagnosis of malfunctions in equipment by an expert system rulebase. A correspondence is defined between text modules including the recommended actions and each of the schemata in the rulebase which produce a diagnosis. After a diagnosis is evaluated as true, the corresponding text modules are evaluated to produce a recommended action. The text modules can also be used for documentation of the rulebase.

Abstract: A method for monitoring low anion concentrations, and particularly sulfate concentrations in aqueous solutions is provided which includes the steps of adjusting the pH of the solution to substantially reduce the presence of hydroxides therein, mixing a nonionic solvent with the solution selected from the group consisting of alcohols, aldehydes, ketones, nitriloes and other water soluble organic compounds which do not contain sulfonate groups, exposing the solution and solvent mixture to an electrode selective for sulfate ions, exposing the mixture to a counter electrode and measuring the difference in voltage across the electrodes. A chilling apparatus may be added to reduce solvent consumption and lower the detection limit.
