摘　　要：对一台1 100t/h循环流化床锅炉进行燃烧优化试验。通过燃烧优化试验发现:锅炉热效率明显提高,稀相区空截面烟气速度显著降低,炉内水冷壁磨损得到有效减轻,一、二次风机及引风机总电流显著减少。通过试验证明:锅炉总风量,一、二次风比率,上、下二次风配比,床压等主要运行参数得到优化。这对于循环流化床锅炉安全、稳定、经济、长周期运行有着非常重要的意义。The boiler thermal efficiency increases significantly by the combustion optimization test on a 1 100 t/h circulating fluidized bed （CFB） boiler. At the same time, the dilute phase zone gas velocity decreases obviously and the abrasion of water cooling heating surface reduces significantly. The total electric consumption of primary air fan, secondary air fan and draft fan decreases prominently. The main operation parameters are optimized. The test is beneficial to safe, stable, economic and long-term operation of the 1 100 t/h Circulating Fluidized Bed Boiler.
