Abstract

The method for erecting a boiler includes erecting a main structure, providing preassembled modules defining a boiler section, installing the modules outside the main structure.

First claim

The invention claimed is:

1. A method for erecting a boiler comprising erecting a main structure: providing assembled modules defining boiler sections; and installing the modules outside the main structure, wherein the installing the modules outside of the main structure includes:
a) providing a module,
b) providing an additional module beside the module,
c) lifting the additional module and connecting the additional module above the module in order to define a group of modules,
d) providing an additional module beside the group of modules,
e) lifting the additional module and connecting the additional module above the group of modules, and
f) repeating steps d) and e) until all modules to be connected to the group of modules are installed.

2. The method of claim 1 , further comprising preassembling the modules on the ground.

3. The method of claim 1 , further comprising pre-assembling the modules outside the final footprint of the boiler.

4. The method of claim 1 , further comprising preassembling the modules during the main structure erection.

5. The method of claim 1 , wherein the installing the modules outside of the main structure includes connecting the modules to one or more other modules and/or to the main structure and/or to a permanent lifting structure.

6. The method of claim 1 , further comprising using, during steps c) and e), lifting structures whose height is as high as the main structure.

7. The method of claim 1 , wherein during step a), the module is provided in its final footprint.

8. The method of claim 1 wherein each preassembled module comprise piping and/or insulation and/or auxiliaries and/or cable trays and/or ducts and/or gratings and/or hand rails and/or piping supports and/or electrical equipment.
