摘要
为进一步提高超临界循环流化床(circulating fluidized bed,CFB)锅炉机组在深度调峰过程中运行的稳定性和经济性,以某电厂350 MW超临界CFB锅炉为例,在分析机组深度调峰过程中遇到的锅炉稳燃及流化、水动力安全、汽动给水泵控制和污染物控制等一系列问题的基础上,提出了相应的控制策略和技术措施。实际运行结果表明,采用该控制策略可实现深度调峰过程中锅炉的长周期良好运行。研究结果可为同类型超临界或者超超临界CFB锅炉机组深度调峰提供参考。
In order to further improve the stability and economy of the operation of supercritical circulating fluidized bed(CFB)boiler units in the process of deep peak regulation,this paper takes the 350 MW supercritical CFB boiler of a power plant as the research object and proposes the corresponding control strategies and technical measures based on the analysis of the series of problems in deep peak regulation,such as steady combustion and fluidization,hydrodynamic safety,steam feed pump control,emission control,and so on.The practical operation results show that by adopting these control strategies,long-term steady operation of the boiler can be achieved.The research results can provide helpful reference for the deep peak regulation of supercritical CFB boilers of the same type and even the ultra-supercritical CFB boilers.
