525t/h CFB锅炉旋风分离器制造工艺简介

大型循环流化床锅炉中的管式旋风分离器的制造所涉及的工艺复杂,装配难度高。以525t/hCFB旋风分离器的制造工艺为例,描述了分片出厂的大型旋风分离器在厂内分片制造、试拼装的工艺方案,分析了制造中重要的工艺难点,诸如大弯曲半径的圆弧形、锥体形管排的成形及组装等,并提出相应的工艺解决方案,重点在于保证旋风分离器的对口装配上。为今后同类大型CFB锅炉的制造,确保产品质量、简化工艺装备设计、加快制造进度提供了工艺措施,积累了经验。

The Brief Introduction About the Manufacture of 525 t/h CFBB's Cyclone Unit

In the large capacity utility CFBB, the manufacture of the cyclone unit is so complicated, and the requirements of assembly is exigent. Considering the dimension of the unit, the cyclone will be left factory by segments. Take the manufacture of the 525 t/h CFBBs cyclone unit for example, this paper introduces the technical project, which includes the cyclones manufacture and the procedure of the segments fit-up. It analyzes the major factors about the techniques and the key steps in the procedure, such as the form and assembly of the arc-panels and cone-panels of the great radius. It also points out the solutions, which stress on the assembly of the cyclone. It provides the ways and means of how to insure the quality of the product, simplify the design of the support structures, and expedite the progress. It accumulates the experiences for the manufacture of the same type of CFBB.
