摘 要 为探究床层温度对生物质循环流化床气化效能的影响，采用玉米秸秆为原料，在不同床层温度的条件下进行气化实验，利用先进的仪器设备，对床层温度进行精确调控，并系统收集与分析气化产物的成分、热值、产气率等数据。实验结果表明，床层温度对气化产物的质量和产量产生了显著影响。在600‰至700‰的温度区间内，氢气和一氧化碳的含量达到了最高值。合理控制床层温度，寻找最佳气化温度窗口，可以显著提升气化产物的质量和产量，其中氢气和一氧化碳的含量分别提高约3%和2.5%，热值和产气率也明显提升。本研究对于提升生物质循环流化床气化效率和产物质量具有重要意义。

Abstract Objective: To investigate the effect of bed temperature on the gasification efficiency of biomass circulating fluidized bed. Methods: Using corn stalk as raw material, gasification test was carried out under different bed temperature conditions. Advanced instruments and equipment were used to precisely regulate the bed temperature, and the data of composition, calorific value and gas yield of gasification products were collected and analyzed systematically. Results: The test results showed that the bed temperature had a significant effect on the quality and yield of gasification products. In the temperature range of 600‰ to 700‰, the content of hydrogen and carbon monoxide reaches the highest value. Conclusion: Reasonable control of bed temperature and search for the optimal gasification temperature window can significantly improve the quality and yield of gasification products. The content of hydrogen and carbon monoxide can be increased by about 3% and 2.5% respectively, the calorific value and the gas production rate can be increased. This is of great significance for improving the gasification efficiency and product quality of biomass circulating fluidized beds.
