摘要： A power generation system having a gas turbine, a fuel cell, an exhaust air circulation line, an exhaust fuel gas supply line, a turbine, an exhaust heat recovery boiler, and at least one exhaust air heat exchanger. The turbine is equipped with a high-pressure turbine, a medium-pressure turbine, and a low-pressure turbine. The exhaust heat recovery boiler is equipped with a high-pressure steam circulation mechanism, a medium-pressure steam circulation mechanism, and a low-pressure steam circulation mechanism. The exhaust air heat exchanger exchanges heat between the steam exchanging heat with the exhaust gas in the high-pressure steam circulation mechanism or the medium-pressure steam circulation mechanism and flowing toward the turbine and the exhaust gas flowing through the exhaust air circulation line, thereby increasing the temperature of the steam and decreasing the temperature of the exhaust gas.

摘要： Method for operating a solar installation. The solar installation includes a solar field with direct evaporation accompanied by the generation of superheated live steam, a turbine for expanding the live steam, and a generator driven by the turbine for generating electrical energy. At least one valve is associated with the turbine by which the amount of live steam fed to the turbine is adjusted. The valve, or each valve, through which the amount of live steam fed to the turbine is adjusted such that an actual value of a live steam pressure occurring upstream of the turbine follows a reference value determined depending on a live steam temperature of the live steam upstream of the turbine.

摘要： A boiler system for producing steam from water includes a plurality of serially arranged oxy fuel boilers. Each boiler has an inlet in flow communication with a plurality of tubes. The tubes of each boiler form at least one water wall. Each of the boilers is configured to substantially prevent the introduction of air. Each boiler includes an oxy fuel combustion system including an oxygen supply for supplying oxygen having a purity of greater than 21 percent, a carbon based fuel supply for supplying a carbon based fuel and at least one oxy-fuel burner system for feeding the oxygen and the carbon based fuel into its respective boiler in a near stoichiometric proportion. The oxy fuel system is configured to limit an excess of either the oxygen or the carbon based fuel to a predetermined tolerance. The boiler tubes of each boiler are configured for direct, radiant energy exposure for energy transfer. Each of the boilers is independent of each of the other boilers.

摘要： A hybrid power generation system using a supercritical CO2 cycle includes a steam power generation unit including a plurality of turbines driven with steam heated using heat generated by a boiler to produce electric power, and a supercritical CO2 power generation unit including an S—CO2 heater for heating a supercritical CO2 fluid, a turbine driven by the supercritical CO2 fluid, a precooler for lowering a temperature of the supercritical CO2 fluid passing through the turbine, and a main compressor for pressurizing the supercritical CO2 fluid, so as to produce electric power. The steam power generation unit and the supercritical CO2 power generation unit share the boiler. The hybrid power generation system may improve both the power generation efficiencies of the steam cycle and the supercritical CO2 cycle by interconnecting the steam cycle and the supercritical CO2 cycle.

摘要： A steam power plant is suggested having, parallel to the high-pressure preheater passage (VW4 to VW6), a heat reservoir (A) which is loaded with preheated condensate in weak-load times. This preheated condensate is taken from the heat reservoir (A) for generating peak-load and inserted downstream of the high-pressure preheater passage (VW4 to VW6) into the condensate line (19.2) resp. the feed water container (8). Thus it is possible to quickly control the power generation of the power plant in a wide range without significantly having to change the heating output of the boiler of the steam generator (1). A steam power plant equipped according to the invention can thus be operated with bigger load modifications and also provide more control energy.
