Method of installing furnace walls of a boiler

A method of installing boiler furnace walls with an upper portion of a boiler proper and a lower portion of the boiler proper, comprising:

• assembling the upper portion of the boiler proper while it is suspended from a top girder module placed on a top of a boiler frame;
• pre-assembling each of four face furnace water wall panels individually for forming the lower portion of the boiler proper respectively on the ground;
• lifting two opposite face furnace water wall panels after the completion of the pre-assembling and suspending them temporarily in position;
• lifting two other opposite face furnace water wall panels after the completion of the pre-assembling;
• moving all four face furnace water wall panels to the designated positions;
• and
• connecting an upper portion of each face of said furnace water wall panels with a lower portion of the upper portion of the boiler proper that is formed by said four face furnace water wall panels being connected while the upper portion of the boiler proper is suspended within the boiler frame,
• wherein a lifting jack is located on the top of said boiler frame, the lifting jack simultaneously hanging the upper portions of the furnace water wall panels and dragging the lower portions on the ground and lifting the lower portions into position.

• assembling the upper portion of the boiler proper while it is suspended from a top girder module placed on a top of a boiler frame;
• pre-assembling each of four face furnace water wall panels individually for forming the lower portion of the boiler proper respectively on the ground beneath the boiler frame;
• attaching buckstays and a wind box to a couple of said four face furnace water wall panels to be one body construction;
• lifting two opposite face furnace water wall panels after the completion of the pre-assembling and suspending them temporarily in position;
• lifting two other opposite face furnace water wall panels after the completion of pre-assembly;
