摘　　要：燃料用气流量恒定是保证制氢转化炉燃烧控制稳定的重要条件。采取流量/压力选择性控制策略,在满足流量稳定的同时,又确保转化炉安全运行。为了避免生产负荷频繁升降可能带来的燃料用气流量的大幅波动,制氢装置采用CS3000系统实现滑动分程控制算法,达到了系统在不同生产负荷区域内能平稳运行的控制目标。Keeping fuel gas flow rate constant is important to ensuring a stable furnace combustion in the hydrogen plant. Adopting the flow/pressure selective control strategy can ensure safe operation of the furnace and keep flow stability. In order to avoid the gas flow fluctuation brought by the production load＇ s frequent rise and decrease, the CS-3000 DCS was used to realize sliding-split control algorithm so that the control objective of keeping the system smooth running in different load areas can be realized.
