摘要
Abstract
The flame center position is a critical factor influencing boiler combustion efficiency,steam temperature,and steam pressure control,and it is also a core element of combustion adjustment.Conventional combustion control strategies in Distributed Control Systems(DCS)lack information,indicators,and adjustment strategies related to the flame center,making it impossible to monitor changes in the flame center position and achieve automatic adjustments.A method is analyzed and verified that uses the working fluid temperature rise in the platen superheater and its rate of change to characterize the flame center position and its variation trend.Operational data indicate that the temperature rise in the working fluid of the platen superheater and its rate of change can serve as effective indicators for representing the flame center position and its variation trend.By integrating these indicators into the DCS,an automatic control strategy for the flame center was developed and successfully applied to a 630 MW boiler.The results demonstrate that the new strategy significantly improves steam dynamic characteristics,substantially reduces the frequency of overtemperature occurrences in steam and wall temperatures,decreases the amount of desuperheating water flow for reheat steam,narrows the fluctuation range of superheated and reheated steam temperatures,and increases their monthly average values.This strategy is of great significance for enhancing the economic efficiency and safety of unit operation.关键词
