AB  - To address the issue of uneven temperature distribution in shale gas oil-based drill cuttings pyrolysis furnaces, a numerical model was developed using Fluent software. The effects of nitrogen flow rate, heating tube spacing, and furnace dimensions on the internal temperature field were thoroughly analyzed from a mechanistic perspective. The results indicated that non-uniform radiation from the heating tubes and flow disturbances induced by the nitrogen stream were the primary causes of localized heat concentration. Under no-load conditions, the maximum deviation between simulated and on-site measured temperatures was 1.5%, validating the model’s accuracy. Furthermore, this study investigated the trade-offs between temperature uniformity, energy consumption, and construction costs. The findings provide a crucial design basis and a reliable simulation platform for developing and optimizing pyrolysis equipment.
