  "abstract": "Particle heat carriers as a heat transport and storage medium for solar thermal applications are an intriguing proposition. As part of the Horizon Europe project PYSOLO, a decoupled solar pyrolysis system is under development, where particulate media serve as an intermediate heat carrier, collecting and delivering heat from a solar receiver to a pyrolysis reactor. A key aspect of this design is a rotary kiln receiver, which offers versatility in terms of particle feedstocks and is the focus of this study. In particular, the modification of a conventional rotary kiln design for application in a concentrated solar tower system is considered. Steep kiln inclination angles up to 30° were studied due to the enhanced solar field optical efficiency and solar flux distributions achievable compared with shallow inclination angles typical of rotary kilns. The particle transport through the rotary kiln, characterized by the time of passage, was studied experimentally at room temperature. The effect of internal structures installed on the inner surface of the kiln on the particle transport behavior was also studied. Both a helix and half ring rib structure significantly increased the passage time with respect to an empty kiln, with a maximum increase of almost 1000% observed with the helix at a 30° inclination angle and rotation speed of 3 RPM. These results indicate the potential of incorporating internal structures to operate a more efficient rotary kiln receiver in solar tower applications.",
