Title:
タービン及び該タービンを有するブレイトンサイクル
Document Type and Number:
Japanese Patent JP6893225
Kind Code:
B2
Abstract:
The present invention relates to the technical field of solar thermal power generation and discloses a turbine and a Brayton cycle including the same. The turbine includes a blade which has a cooling working medium inlet and a cooling working medium jet orifice. The blade is provided as a cavity with hollow interior; the cooling working medium inlet is located inside the blade; the cooling working medium jet orifice is provided on the blade surface on which is provided with a spectral conversion coating; the spectral conversion coating can convert the heat on the blade surface into conversion characteristic band radiation which is radiation energy adjacent to cooling working medium characteristic band radiation of a cooling working medium. The turbine of the present invention adopts a characteristic spectral coating and a jet cooling technology to enhance the cooling effect for a turbine blade, so as to ensure the safe and efficient operation of the turbine, and increase the temperature of a circulating working medium while protecting the turbine blade, and improve the system efficiency of the Brayton cycle.
