Research on Control System of 600 MW Supercritical Circulating Fluidized Bed Boiler
摘要
Abstract
The 600 MW supercritical circulating fluidized bed(CFB) unit has a significant character with more complex boiler properties. So the control system of supercritical CFB unit has important significance for the safe and stable for the boiler,and the control strategy is the core and difficulty of control system. Burning carbon in the CFB furnace is the dominant factor. It is the main reason causing more combustion lag than the pulverized coal fired boiler. This paper analyzed the mechanism structure model of burning carbon in the boiler and estimated the burning carbon storage capacity in a 600 MW supercritical CFB boiler furnace. The state quantity was applied in the boiler for the coal control, the feed water control, and the wind control. It improves the dynamic response characteristics of load, and the same time can stable the main steam pressure and the main steam temperature. The practice proves the effectiveness of the proposed control strategies and the structure models.关键词
