In this paper, study on a volumetric receiver which use for solar energy season storage and heating system. This type of volumetric receiver has a high heat capacity, so that volumetric receiver can be ensured under severe weather conditions. In order to provide a reference for design and modification of volumetric receiver, the heat transfer characteristics of the volumetric heat absorber are studied. The influence of extinction coefficient and wind speed on the heat transfer characteristics of the volumetric receiver is analyzed by single factor analysis.
