摘要

对 35t/h循环流化床生活垃圾焚烧锅炉的汽包水位自动控制方式进行了研究。针对垃圾焚烧炉炉膛负荷波动较大

及给水调节阀门执行机构的调节精度较低的现状

在传统三冲量串级控制方式的基础上

采用模糊控制策略对主、副回路的PID控制参数进行分区域调整

强调在被控参量处于不同范围时PID参数的分离作用。同时

主、副控制回路采用异步控制方式

可有效提高汽包水位的调节精度

减少水位调节的振荡次数。

Abstract

Study has been carried out for automatic control mode concerning drum-level of a 35 t/h CFB boiler for municipal solid waste (MSW) incineration. Directing against the present situation of comparatively large load fluctuation in the furnace of MSW incinerator

and compavatively poor adjusting accuracy of actuator for feed-water control valve

on the basis of traditional three impulse cascade control mode

the PID control parameters of the main loop and the auxiliary loop have been sectionally adjusted by adopting fuzzy control strategy

emphasizing the isolating function of PID parameters during the time of controlled parameter being in different ranges

at the same time an asynchronous control pattern is adopted for the main and auxiliary control loops

enhancing greatly the regulating accuracy of water-level in the boiler durm

decreasing the number of oscillation in water-level regulation.
