Abstract: A central solar receiver comprises an axisymmetric housing having front and rear ends and having an aperture at the front end, an elongated tubular window mounted in the aperture co-axially with the housing, a volumetric solar absorber disposed within the housing and extending around and along the elongated window for absorbing solar radiation that has passed therethrough; and working fluid ingress and egress formed in the housing so as to, respectively, inject thereto, and withdraw therefrom, a pressurized working fluid in a manner enabling the working fluid interaction with the volumetric absorber. The window has an open front end which is secured to the housing at the front end thereof, and a closed rear end which is disposed adjacent the rear end of the housing and is free of any securing thereto.
