Erection method of laminated beams of boiler structure

Owing to space limitation,the upper and the lower sub beams of the three laminated beams for the 300 MW unit W firing boiler in Shaoguan Power Plant have to be erected separately before being combined.Therefor,the designed features of the laminated beams are analyzed and a method presented,which enables successful erection by solving the crane layout problem and the downward bending of the lower beams when preliminarily erected.
