摘　要: 锅炉控制系统可以分为汽包水位控制系统和燃烧控制系统。燃烧控制系统包括:蒸汽压力控制系统、炉膛负压控制系统和经济燃烧控制系统。维持汽包水位、蒸汽压力和炉膛负压规定的范围内,实现锅炉的经济燃烧,是保证锅炉安全运行的必要条件,也是锅炉正常运行的主要指标。本文对汽包水位控制在三冲量PID控制的基础上,采用了延时控制和限幅控制,实现汽包水位的稳定运行。为了实现经济燃烧,本文采用了模糊自寻优控制方式调整风量的变化,实现燃煤的经济燃烧。

Abstract: Boiler control system is composed of drum water level control system and combustion control system. Combustion control system is composed of steam pressure control system and combustion economical control system. Maintaining drum water level in the set range and maintaining steam pressure in the set range and maintaining hearth negative pressure in the set range are necessary condition of ensuring boiler's safety running and main index of boiler's running. Based on three impulses cascade control, system adopts delaying control and limit-scope control, and realizes stabile movement of water level. The system realizes the coal's economical combustion through adopting self-adopting and self-optimizing Fuzzy control method to modify the ratio parameter of wind to coal.
Keywords: boiler; water level control; combustion control; fuzzy control
