Abstract: In the boiler steam drum dismantlement engineering of the Zhanjiang Orimusion Power Plant, the steam drum is required to be reused after dismantled. The size of the drum is about 27.0m×4.0m×3.5m（length × width × height）, the hoisting weight is about 2400kN. The steam drum dismantlement hoisting scheme and the technical requirement were introduced. The methods of load computation, the design of the hoisting equipment, the strength check and the stand column stability check were given. After the scheme was implemented, the hoisting task was finished successfully.

Key words: 600MW unit, steam drum dismantlement, hoisting scheme, strength check, stand column stability
