Ceramic foams have widely been used as radiation receivers and heat exchangers, with the excellent characteristics of radiation absorption and heat transfer. In this paper, experimental investigations, on the characteristics of the radiation absorption and conversion, the heat transport of coupled radiation with conduction, the convection heat transfer between the gas phase and solid phase in the ceramic foams, were performed. The influences of the physical parameters of the ceramic foams were analyzed, on the radiation absorption, energy conversion and heat transport in tne ceramic foams. The results show: For the ceramic foams used as radiation receiver, the structure of the pores, the air flow velocity, and the parameters of the geometry have a strong effect on the temperature distribution, the radiation absorption, the energy conversion and the heat transport in the ceramic foams.
