摘要:
针对国产220 t/h循环流化床锅炉的特点,结合工程的具体实际,介绍了一种实现全自动启动循环流化床锅炉的控制策略.采用两台结构简单的就地控制装置实现对锅炉点火用设备进行就地操作和远方DCS切换.在DCS中,用一对独立的控制器(DPU)实现在锅炉启动过程及常规运行时都适用的炉膛安全系统(FSS)和燃烧器控制系统(BCS)的功能.着重叙述了油系统泄漏试验、炉膛吹扫、点火启炉和烟风系统的顺序控制逻辑;指出了CFB锅炉在启动过程中的投煤条件和投煤方式,以及各次风量与给煤量的匹配要求.该控制策略的应用大大降低了锅炉运行人员在机组启动时的操作强度,提高了锅炉运行的自动化水平.
Abstract:
Th is article describes the contro l po licy adopted in rea lizing the fu lly-autom atic start- up o f the dom estic 220 t/h CFBB based on its character istics and in com bina tion w ith practice o f the pro ject. The po licy is character ized by the sim plicity of two se ts o f on- spot con tro l appa ra tus, w hich func tion as on- spot man ipu la ting and rem ote DCS sw itching for the contro l of furnace ign ition. A specific dual the Distr ibuted Process Un it ( DPU ) in DCS is used to realize the function of furnace safety system ( FSS) and burner con tro l system ( BCS) dur ing furnace start-up phase and norm a l run. The emphasis is g iven in this a rtic le on the sequence contro l log ic o f fuel o il leakage detec tion, furnace purge, ignition dur ing start-up, sm oke / a ir system. The cond ition and m e thod of coa l feed ing, the vo lum e and sequence o f a ir and coa l for every feeding are a lso elaborated. W ith this con tro l po licy, thewo rk loads o f the ope ra to rs during bo ile rs’ start- up are greatly reduced and the au tom ation of bo iler operation is improved.
