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 hy-drogen 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.
