摘要

某330 MW循环流化床机组进行深度调峰改造后

能长期保持30%负荷段运行

但深度调峰时机组存在热效率差、单位发电成本高、难以投入自动的问题。本文通过分析该机组深度调峰运行数据

建立深度调峰性能分析评价流程;在对机组深度调峰时的热力性能、发电成本等问题的分析过程中

研究了入炉煤粒径与流化风量对炉膛物料分布的影响

并计算了深度调峰的经济性。结果表明:循环流化床机组在深度调峰条件下具有天然优势与可行性;深度调峰改造后

该330 MW循环流化床机组每日可稳定调峰6 h以上

初步计算每年可以获得约1 700万元的效益。本文研究结果可以为今后循环流化床机组深度调峰运行的改造提供参考。

Abstract

After deep peak-regulating retrofitting

a 330 MW circulating fluidized(CFB) bed unit can maintain 30% load segment operation for a long time. However

the problems of poor thermal efficiency

high power generation cost and difficulty in putting into automatic operation are more prominent in deep peak-regulating. By analyzing the deep peak-regulating operation data

the performance evaluation process of deep peak-regulating was established in this paper. In the process of analyzing the thermal performance and generation cost of the unit and other problems during deep peak-regulating

the influence of coal particle size and fluidized air volume on furnace material distribution was studied. Moreover

the economics of deep peak-regulating were calculated. The results show that

the CFB unit has natural advantages and feasibility under deep peak-regulating conditions. After the retrofitting

the 330 MW CFB unit can perform stable peak-regulating for more than 6 hours per day

and get about 17 million yuan in benefits. The research results in this paper can provide a reference for the future transformation of deep peak-regulating of CFB units.
