为研发新型气体热载体干馏技术，自主搭建了气体热载体干馏炉试验台。对不同进气方式下的炉内温度分布进行了试验研究。通过采集干馏炉内温度数据，得到炉内沿半径方向和高度方向上温度分布。分析了中心管和边壁同时进气的特点，并与中心管单独进气时进行了对比，研究了联合进气时的温升特性。试验结果表明：中心管单独进气时靠近边壁处存在滞留层，温度较低，与炉内中心处温差较大。采用中心管联合边壁进气可以较大程度改善滞留层温度较低的问题。联合进气时，炉内沿高度方向上升温速率有所不同。试验结果将为进一步研发和改进油页岩气体热载体干馏炉布气方式提供参考和依据。

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.
