Claim:
1. An apparatus for heating a working fluid of a gas turbine-solar power generation system, comprising a cold air flow channel, a heat collecting cavity, and a hot air passage that defines a hot air flow path that are sequentially connected, the cold air flow channel is formed between an internal insulation layer and an external insulation layer, the heat collecting cavity is formed by a primary heat absorbing body and a secondary heat absorbing body, the hot air passage is formed by connecting an inner housing on the front side to a supplemental heating section on the rear side, the heat collecting cavity is separated from the cold air flow channel by the secondary heat absorbing body and separated from the hot air passage by the primary heat absorbing body; characterized in that the apparatus further comprises a gas burner for heating a primary heating air within the supplemental heating section when solar power is insufficient, and the burner is arranged at the supplemental heating section within a burner housing which defines a cavity through which supplemental heated air flows along a supplemental air flow path, the cavity is offset from the hot air flow path so that the supplemental air flow path is transverse to the hot air flow path and is in fluid communication therewith.
