Abstract: For the investigation of new technology of oil shale retort with gas heat carrier,a lab-scale retort was built. The temperature distribution inside the retort was investigated with different gas-intake arrangements. Temperature distributions along the radial direction and vertical direction were obtained by collecting retort temperature data. The characteristics of gas-intake through side-arranged headers combined with central tube were investigated. Comparison between gas-intake through central tube alone and that through side-arranged headers combined with central tube was made,and investigation of the heating characteristics of combined two gas-intake arrangements was performed. With gas intake through central tube alone,there existed a lag zone around the retort inside wall,and its temperature was much lower than retort central temperature. Combined two gas-intake arrangements could significantly resolve the problem related to central tube intake alone as illustrated above. Heat-up rate varied along the height of retort when combined two gas-intake arrangements was used. The experimental results would provide reference and basis for further research and improvement of gas-intake arrangements in oil shale retort with gas heat carrier.
