摘　　要：简要介绍了碱回收燃烧工段的工艺流程,重点阐述了燃烧工段节能控制系统方案,即完成了送风、引风、炉膛负压控制子系统的设计及其硬件实现,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,降低了运行成本。The flow sheet of the combustion in alkali recovery is briefly introduced and the energy-saving controlling scheme is described including the design and hardware configuration of the sub-systems for air input, air output and hearth vacuum control. Because of the application of tranducer, the system can be accurately adjusted and has a remarkable energy-saving effect with the running cost reduced.
