寒冷地区立式空预器积灰解决措施

Solution for Vertical Air Preheater Ash Accumulation in Cold Areas

循环流化床锅炉受热面的积灰问题严重影响锅炉的经济安全运行,由于分离器分离效率的持续提高,尾部受热面的积灰问题日益凸显,针对寒冷地区立式空预器用户,提出了一套从设计到运行各个方面综合解决立式空预器积灰问题的措施。

The ash accumulation problem of the heating surface of the circulating fluidized bed boiler seriously affects the economic and safe operation of the boiler. Due to the continuous improvement of the separator separation efficiency,the ash accumulation problem of the rear heating surface is increasingly prominent. For cold users, a set of measures is proposed to comprehensively solve the ash accumulation problem in all aspects from design to operation.
