With an installation construction method for boiler facilities, the boiler facilities comprise a boiler building configured of a steel structure, and a boiler main unit suspended within the boiler building from the upper portion of the boiler building. A portion of the boiler building is constructed, a portion of the boiler main unit is suspended from the upper portion of the partially-constructed boiler building, and while the remaining steel structure portions are being added to the partially-constructed boiler building so as to construct the boiler building, the remaining portions of the boiler main unit are added to complete the boiler main unit.

Installation construction method for boiler facilities

New and useful method of installing furnace walls for a boiler that does not require dedicated temporary lifting mechanism and reduces the installation work period significantly is disclosed. The method of installing furnace walls for a boiler configured with an upper portion of boiler properand a lower portion of boiler proper, temporally suspending two left and right face furnace water wall panelsamong four furnace water wall panels, the upper portion of boiler proper is assembled while it is hanged from a top girder modulepositioned on the top portion of a center portion in a boiler frame, a furnace rear walland a furnace front wallamong the furnace water wall panels are hanged sequentially, the temporally suspended two left and right face furnace water wall panelsare moved to designated positions, and the upper ends of the furnace water wall panelsandare connected with the lower end of the upper portion of boiler proper
