Combined with the characteristic of thermal compensation of flue duct

as well as the calculation method of compensation quantity

type selection and installation of compensator was analyzed.Results show that

to enhance compensation ability of the compensator

methods such as pre-drawing

precompression

transverse eccentric installation and other ones should be adopted

according to concrete situation during the installation of the compensator in the flue duct.On the premise of satisfying the installing requirements

the compensator should be as close as possible to the interface that has larger displacement on the flue duct

and near the support and hanger to prevent instability of the compensator that caused by excess layout of compensators between the adjacent fixed points.When metal compensator is used in the flue duct

to lessen the force and moment that the interface bears

elastic reaction and moment produced by compensator on the duct and interface should be paid more attention to.
