摘要： A method of operating a power generation system is provided. The system includes) a turbine, a regenerative heat exchanger, a vapor generator and a distiller/condenser having multiple condensing elements. The turbine expands a vaporized multicomponent working fluid to produce power. The regenerative heat exchanger transfers heat from a lean hot multicomponent working fluid having a relatively low concentration of a component of the multicomponent working fluid to a rich cool multicomponent working fluid having a relatively high concentration of the component to thereby cool the lean hot multicomponent working fluid. The vapor generator vaporizes the cooled multicomponent working fluid to form the vaporized multicomponent working fluid. The multiple condensing elements of the distiller/condenser condense the expanded multicomponent working fluid to form the lean hot multicomponent working fluid. To operate the system, a first portion of the expanded multicomponent working fluid is condensed in a first of the multiple condensing elements. A second portion of the expanded multicomponent working fluid is condensed in a second of the multiple condensing elements to form the lean hot multicomponent working fluid. The flow of the condensed first portion of expanded multicomponent working fluid from the first condensing element is regulated to regulate the amount of the condensed second portion of expanded multicomponent working fluid in the second condensing element.

摘要： A method of operating a Kalina cycle power generation system, includes directing a stream of vaporized binary working fluid to a turbine where it is expanded to produce power. A first portion of the expanded binary working fluid is directed to a distiller/condenser having multiple heat exchangers where, using the multiple heat exchangers, it is transformed into a first concentration binary working fluid, having a first concentration of a component of the binary working fluid, and a second concentration binary working fluid, having a second concentration of the component. At least the first concentration binary working fluid directed to a regenerative heat exchanger. A second portion of the expanded binary working fluid is directed to the regenerative heat exchanger where the first concentration binary working fluid is transformed into a vaporized binary working fluid and the second portion of expanded binary working fluid is transformed into a feed binary working fluid. The feed binary working fluid is directed to a vapor generator where it is vaporized. The binary working fluid flow within the distiller/condenser is actively regulated to maintain a desired relationship between the multiple heat exchangers.

摘要： A method of operating a power generation system, such as a Kalina cycle power generation system, which includes a turbine, regenerative heat exchanger and vapor generator, is provided. The turbine receives a stream of first working fluid and expands the first working fluid to produce power. The regenerative heat exchanger receives a stream of the expanded first working fluid from the turbine and a stream of second working fluid, and transfers heat from the expanded first working fluid to the second working fluid to heat the second working fluid and condense the expanded first working fluid. The vapor generator receives a stream of the condensed first working fluid and transfers heat from an external heat source to the condensed first working fluid to heat the condensed working fluid for use in the stream of first working fluid. The system is operable in a first state of substantial equilibrium with the stream of second working fluid being received at a first flow rate and in a second state of substantial equilibrium with the stream of second working fluid being regulated so as to be received at a second flow rate, different than the first flow rate.

摘要： A method of operating a power generation system is provided. The system includes a turbine, a distiller/condenser, a boiler, and a superheater. The turbine expands a superheated multicomponent working fluid to produce power. The distiller/condenser transforms the expanded multicomponent working fluid into first and second concentration multicomponent working fluids. The first concentration multicomponent working fluid has a first concentration of a component of the multicomponent working fluid. The second concentration multicomponent working fluid has a second concentration of the component which is different than the first concentration. The boiler vaporizes a feed multicomponent working fluid. The superheater superheats the vaporized feed multicomponent working fluid to form the superheated multicomponent working fluid. In operating the system, the temperature of the vaporized multicomponent working fluid is sensed. The first and second concentration multicomponent working fluids are combined to form a third concentration multicomponent working fluid. The third concentration multicomponent working fluid has a third concentration of the component which is different than the first and second concentrations. The third multicomponent working fluid is combined with the vaporized multicomponent working fluid to adjust the temperature of the vaporized multicomponent working fluid and thereby regulate the temperature of the superheated multicomponent working fluid.

摘要： A method of operating a power generation system is provided. The system includes a turbine, a regenerative heat exchanger, a boiler, and a superheater. The turbine receives a stream of first working fluid and expands the first working fluid to produce power. The regenerative heat exchanger receives a stream of the expanded first working fluid from the turbine and a stream of second working fluid, for example from the RHE or DCSS of a Kalina type system. The exchanger transfers heat from the expanded first working fluid to the second working fluid to heat the second working fluid and condense the expanded first working fluid. The boiler receives and vaporizes a stream of the condensed first working fluid. The superheater receives and superheats the vaporized stream of first working fluid and the heated stream of second working fluid to form the stream of first working fluid. In operating the system, first heat is transferred from the expanded first working fluid to the second working fluid to superheat the second working fluid and condense the expanded first working fluid. Condensed first working fluid from another stream of the condensed first working fluid is combined with and thereby desuperheats the superheated second working fluid. Second heat from the expanded first working fluid is transferred to and thereby heats the desuperheated second working fluid without condensing the expanded first working fluid to form the heated stream of second working fluid.

摘要： A method of operating a power generation system is provided. The system includes a turbine, a regenerative heat exchanger, and a vapor generator. The turbine receives a stream of working fluid and expands the working fluid to produce power. The regenerative heat exchanger has a plurality of condensing heat exchangers which transfer heat from the expanded working fluid to condense the expanded working fluid. The vapor generator vaporizes the condensed portions of working fluid to form the stream of working fluid. In operating the system, a respective portion of the expanded working fluid is directed to each of the condensing heat exchangers, and the amount of condensed working fluid at at least one of the condensing heat exchangers is regulated.

摘要： A control system for a fuel-fired furnace and more specifically the control of the stoichiometric ratio of the combustion process occurring within the furnace of a steam generating power plant. The control system, when so employed, is capable of regulating the distribution of air flow to the combustion process such that the formation of oxides of nitrogen are maintained at acceptable levels. The control system includes in general a stoichiometric subsystem that determines the mass flow rate of air required to maintain the stoichiometric ratio within the combustion process; an override protection subsystem which ensures control precedence of the windbox-to-furnace pressure differential over the stoichiometry subsystem; and an overfire air subsystem that acts to apportion air flow amongst the various levels of overfire air within the boiler.
