330 MW循环流化床锅炉燃烧调整试验研究
摘要:为解决某330 MW循环流化床(circulating fluidized bed,CFB)锅炉运行床温分布不均匀、炉内受热面磨损爆管等问题,进行了锅炉的燃烧优化调整试验。结果表明,通过优化一次风量、总风量及风室压力等关键运行参数,确定了最佳运行工况及参数,降低了锅炉灰渣平均可燃物含量,使锅炉热效率提高0.85%。燃烧优化调整试验还使一、二次风机总功率降低了0.8 MW,厂用电率相应降低了0.24%,锅炉的运行安全性和经济性由此得到进一步提高。
Abstract:A circulating fluidized bed (CFB) boiler of the 330 MW unit have problems such as nonuniform bed temperature, heating surface wear, tube burst and so on. Combustion optimizing adjustment test was carried out to solve these problems. Adjustment test result show that through key operation parameters such as optimizing primary air flow, total air flow and wind-box pressure, the best operation condition and parameters are determined, average carbon content in bottom ash and fly ash is reduced, boiler thermal efficiency is increased by 0.85%. Total power of primary air fan and secondary air fan is reduced by 0.8MW, auxiliary power rate also is decreased by 0.24%. Operational safety and economy of the boiler has been further improved.
