Description

Technical Field

[0001] The utility model relates to the technical field of steam turbine condenser installation tools, in particular to a special tool for installing a steam turbine condenser partition. Background Art

[0002] A gas-fired power plant is a circulation system that utilizes a gas turbine, a generator, a waste heat boiler, and a steam turbine. It recovers the high-temperature exhaust gas discharged by the gas turbine through a waste heat boiler and converts it into steam, and then injects the steam into a steam turbine to generate electricity. A steam turbine is a mechanical device that converts thermal energy into mechanical energy.

[0003] In addition to being sealed and connected to the tube sheets at both ends, all cooling tubes of the steam turbine condenser are also provided with supporting baffles. These supporting baffles are usually welded and fixed to the condenser cylinder, so that the cooling tube bundle composed of the entire condenser cooling tubes is divided into multiple partitions in the length direction. In order to ensure that the baffles can effectively withstand the external pressure on the condenser cylinder, the baffles are usually designed to be welded to the cylinder. Since the condenser cylinder is a whole, the baffles need to be directly supported by a crane and hoisted into the condenser cylinder one by one from both ends or one end of the condenser cylinder. However, the hoisting steps are cumbersome, the assembly is difficult, and the construction time is long. Summary of the invention
