英文摘要：

The scaling problems of ash and slag conveyance pipes in coal-fired power plants affect the normal operation of generating sets. An online pipe scale cleanout machine is designed, which can remove scaling without shutdown of the generating sets, avoiding the traditional pickling corrosion destroying of pipes and environmental pollution,at the same time,significantly reducing the costs. A three-dimensional CAD modeling is used in the design process, and the finite element method is used to check and analyze key parts, therefore, the design cycle is shortened and the design efficiency is improved.
