摘要： The present disclosure provides methods, assemblies, and systems for power production that can allow for increased efficiency and lower cost components arising from the control, reduction, or elimination of turbine blade mechanical erosion by particulates or chemical erosion by gases in a combustion product flow. The methods, assemblies, and systems can include the use of turbine blades that operate with a blade velocity that is significantly reduced in relation to conventional turbines used in typical power production systems. The methods and systems also can make use of a recycled circulating fluid for transpiration protection of the turbine and/or other components. Further, recycled circulating fluid may be employed to provide cleaning materials to the turbine.

摘要： The present disclosure provides systems for carbon capture in combination with production of one or more industrially useful materials. The disclosure also provides methods for carrying out carbon capture in combination with an industrial process. In particular, carbon capture can include carrying out calcination in a reactor, separation of carbon dioxide rich flue gases from industrially useful products, and capture of at least a portion of the carbon dioxide for sequestration of other use, such as enhanced oil recovery.

摘要： The present disclosure relates to systems and methods that provide power generation using predominantly CO2 as a working fluid. In particular, the present disclosure provides for particular configurations for startup of a power generation system whereby the combustor may be ignited before the turbine is functioning at a sufficiently high speed to drive the compressor on a common shaft to conditions whereby a recycle CO2 stream may be provided to the combustor at a sufficient flow volume and flow pressure. In some embodiments, a bypass line may be utilized to provide additional oxidant in place of the recycle CO2 stream.

摘要： The present disclosure provides an integrated power generating system and method that combines combustion power generation with solar heating. Specifically, a closed cycle combustion system utilizing a carbon dioxide working fluid can be increased in efficiency by passing at least a portion of a carbon dioxide working fluid through a solar heater prior to passage through a combustor.

摘要： The gas turbine facility 10 of the embodiment includes a combustor 20 combusting fuel and oxidant, a turbine 21 rotated by combustion gas, a heat exchanger 23 cooling the combustion gas, a heat exchanger 24 removing water vapor from the combustion gas which passed through the heat exchanger 23 to regenerate dry working gas, and a compressor 25 compressing the dry working gas until it becomes supercritical fluid. Further, the gas turbine facility 10 includes a pipe 42 guiding a part of the dry working gas from the compressor 25 to the combustor 20 via the heat exchanger 23, a pipe 44 exhausting a part of the dry working gas to the outside, and a pipe 45 introducing a remaining part of the dry working gas exhausted from the compressor 25 into a pipe 40 coupling an outlet of the turbine 21 and an inlet of the heat exchanger 23.
