直立炉、焦炉荒煤气微压自动调节的改进

摘要

This article presents the use of rapid dampers in a raw gas pressure control system to change the pressure tap position of a speed governor for improving the top pressure of a vertical retort and a tar oven. This technological improvement can keep the pneumatic or electric butter fly valves working in a stable way and the raw gas micropressure proper under automatic control.%本文介绍了对直立炉、焦炉炉顶压力，使用快速阻尼器改进变速器取压点位置等技改措施，确保气动蝶阀和电动蝶阀的稳定运行，实现荒煤气微压自动调节。
