直立式炭化炉荒煤气微压自动调节的改进

Improvement of Micro-pressure Automatic Control of Raw Gas from Vertical Retort

介绍了对直立炉炉顶压力 ,使用快速阻尼器 ,整定PID参数 ,实现荒煤气微压自动调节的技术及其应用效果。

When the production of raw gas from vertical retort is low,by means of changing the pressure measure point of the blower feedback to the front of the primary cooler, using the rapid damper, adjusting the PID values, the micro-pressure of raw gas from vertical retort can be controlled automatically to improve the gas quantity.
