摘要
根据江苏贾汪发电有限公司135 MW机组440 t/h循环流化床锅炉的实际运行情况,从循环流化床锅炉的优化燃烧角度进行了锅炉运行优化和燃烧调整试验。通过热态燃烧风量调整、煤质对燃烧的影响、掺混煤燃烧及燃料破碎设备等试验,分析了总风量、一次风量及上下二次风量变化对灰渣可燃物含量的影响,确定了锅炉的经济燃烧调整和风量分配方式,可指导调整循环流化床锅炉在各种运行情况下的燃烧工况,从而实现锅炉优化运行的目标。
The optimal burning adjustment tests for 440 t/h circulating fluidized bed boiler of Jiawang Electrical Power Corporation were studied,and the various tests such as burning air flow changes,mixed coals and different size coal particles burning etc. were carried out. The testing results and the relevant conclusions can help to adjust the burning state in various practical cases for circulating fluidized bed boilers,and the object of optimal running for boilers can be realized.
