FIELD: power engineering. ^ SUBSTANCE: in solar plant with hub, comprising cylindrical receiver in focal area, hub is arranged in the form of axisymmetric mirror reflector, produced from two coupled large and small quarters of radius circumferences R and r (R>r>0), lower base of receiver is distanced from plane of hub midship section at the distance a=R-r, radius of receiver base is equal to radius of smaller circumference, upper base of receiver is distanced from plane of hub midship section by distance b, height of receiver equals h=a-b, and as solar plant with hub is oriented at the Sun, h<R-r, and geometric coefficient of concentration equals ^ EFFECT: increased concentration of radiation at receiver of solar radiation with normal fall of solar rays. ^ 4 cl, 3 dwg |
