Boiler structure and method of assembly

Abstract

A support structure for a boiler envelope, for example being the boiler envelope of a boiler thermal plant, a boiler structure so supported, and a method of supporting a boiler, are described. The support structure includes a support platform structure, comprising a part of the primary load bearing boiler cold structure for the boiler envelope, and adapted to engage with and thereby carry at least a major part of the static load of the boiler envelope. The support platform structure is provided surroundingly about the boiler envelope at a support platform level substantially below full envelope height and provided with associated further boiler cold structure in such manner that at least the substantial majority of the boiler cold structure is at or below the support platform level and preferably such that essentially all the boiler cold structure is at or below the support platform level and only elements of the boiler hot structure and the boiler pressure parts extend above the support platform level supported by the boiler cold structure.
