Abstract

A method for assembling a steam generator includes parallel assembly of the boiler framework and preassembly of assembly modules, and hoisting of the assembly modules into the boiler framework. The outer roof section of the boiler framework roof is then assembled. The inner roof section and the internal components are assembled simultaneously with assembly of the boiler wall in the upper section of the steam generator. The segments of the external support pipes are mounted into the assembly modules and subsequently connected at their module joints the external support pipes are mounted in the final position in the outer roof section. The buckstays and the header tie bars are mounted headers to the boiler wall or to the external support pipes. The auxiliary steel structure of the assembly modules the suspension equipment of the curtain walls are dismantled.
