摘要
通过对UG-260/9.8-M2型CFB锅炉进行分析,发现在调试、运行期间存在锅炉本体晃动较明显、床料流化不均、播煤不均,返料不畅等问题。为了解决这些问题,主要采取了以下措施:增加止晃装置膨胀间隙和数量、对布风板耐火材料重新浇筑、增加播煤风量、改造回料器进风管及风帽等。改造后的锅炉运行表明锅炉本体无明显晃动,炉膛内物料流化均匀,播煤均匀且返料正常。
The analysis of UG-260/9.8-M2 CFB （circulating fluidized bed） show that, the furnace itself shakes violently ,the bed doesn＇t fluidize materials equably ,the coal couldn＇t be spreaded uniformly, the materials couldn＇t be recycled smoothly during debugging and operating. To resolve these problems, add anti-shaking devices and their expansion clearance, repour fireproofing of air distributor, increase air quantity which serves to spread coal, transform blast pipe and blast cap of rotary feeder. After transformation, all the above problems could be resolved.
