摘　　要：阐述了发生炉煤气站自动恒压供气的必要性,介绍了用气点煤气流量变化与煤气加压机、空气鼓风机和饱和温度的联动调节方案,并由此组成闭环控制调节的发生炉煤气站自动恒压供气系统。应用表明,该系统联动反应灵敏准确,煤气负荷调节能力可以稳定满足每分钟30%的负荷变化。The necessity of automatic constant pressure gas supply system for the coal gas station was expressed. The joint regulation program between the changes of gas flow at gas consumption point and gas compressor, air blower, as well as saturated temperature was introduced. The closed-loop con- trolled and regulated automatic constant pressure gas supply system of the gas station was formed. Practical application shows that linkage of the system is responsive and accurate. Gas load regulation capacity can be stabilized to mcct the load changes of 30% per minute.
