Hydrogen-fired gas turbine power generation system with nano-aerosol cooling

Abstract

The invention discloses a hydrogen-fired gas turbine power generation system with nano-aerosol cooling, wherein a nanofluid containing nano solid particles is sprayed into the secondary air cooling structure of the hydrogen-fired gas turbine to form a nano-aerosol cooling medium, which enters the combustion chamber and the cooling channel of the turbine to complete cooling, then flows into the high-temperature combustion gas through the air film hole, passes through the combustion chamber, the gas turbine and the steam turbine, enters the condensation recovery device to obtain water and solid particles, and finally enters the nano-fluid preparation device to obtain the nano-fluid again. Aiming at the problem that the traditional air cooling technology is difficult to meet the cooling demand of the hydrogen-fired gas turbine, the invention adds nano-particles into the secondary cooling air to form a nano-aerosol cooling medium, and while not blocking the cooling channel and wearing the metal, the cooling performance of the nano-aerosol cooling medium is greatly improved by changing the thermophysical properties of the cooling medium, enhancing the turbulence of the working medium flow, and utilizing the phase change latent heat of the nano-particles, thereby improving the economy of the system.
