摘　　要：介绍了碱回收燃烧工段的工艺流程,完成了黑液调节、送引风、锅炉供水、燃烧过程控制及连锁保护等子系统的设计及其软硬件实现,并将变频器运用于其中,既可以很细微地调节送、引风量,又有显著的节能效果,极大地降低了运行成本。The paper presents the technological process in a combustion section for alkali recovery and the design of some subsystems to control black liquids, air input and output, bolier water supply, combustion process and linkage protection along with the implementation of their software and hardware. The system makes use of frequency converters to perform the fine adjustment of the amount of air input and output ,thus effecting a great saving on energy and reducing the running cost.
