The problems of platen reheater in 480 t/h boiler

such as deformation

tear

and tube-burst etc.

of thermal power plant subordinated to China Salt Jilantai Chlorine-Alkali Chemical Co Ltd

have been presented

it is believed that the main causes leading to deformation of the platen reheater are as follows:defects existing on oxpansion joint of the wall-entrance sealing box at top of the platen reheater constructed according to the original design;insufficent pretightening load applied to the constant force spring hanger of said hanging platen reheater;the guide means weren't installed for the outlet header of platen reheater;overtemperature phenomenon occurred on tube-wall of the platen reheater etc..Through retrofitting

the deformation of platen reheater can be controlled

the failures of tube-burst and boiler shutdown haven't occurred again

boasting remarkable effectiveness.
