Abstract

An alignment device for aligning a tube panel with a plurality of pipes system and a method of performing the alignment is provided. The alignment device is used in a panel comprising a plurality of tubes having an inner diameter and an outer diameter. The alignment device includes a cylindrical first portion sized to fit within the tube inner diameter. A tapered second portion is provided opposite the cylindrical first portion, the tapered second end having a first end diameter that is substantially the same size as the outer diameter.

First claim

What is claimed is:

1. A method of installing a boiler tube panel into a system, the method comprising:
providing a boiler having a plurality of pipes extending therefrom, the plurality of pipes being connected to a mud drum;
providing a plurality of inserts, each of the plurality of inserts having a first tapered portion with a first end diameter;
welding a plurality of tubes together to form the panel, each of the plurality of tubes having an outer diameter;
placing a respective one insert of the plurality of inserts in an end of each of the plurality of tubes, wherein the first end diameter is substantially the same as the outer diameter;
aligning the each of the first tapered portions of the plurality of inserts with the plurality of pipes;
inserting each of the first tapered portions of the plurality of inserts into at least one of the plurality of pipes;
inserting the plurality of tubes into the plurality of pipes;
removing the inserts from the plurality of tubes after the step of inserting the plurality of tubes into the plurality of pipes;
wherein the step of removing the inserts includes engaging a loop on an end of a cable or chain attached to an end of the insert; and
wherein the step of removing the inserts includes sliding the inserts through the plurality of pipes into an interior of the mud drum.

2. The method of claim 1 , further comprising coupling the plurality of tubes to the plurality of pipes after the step of inserting the plurality of tubes into the plurality of pipes.

3. The method of claim 1 , wherein:
each of the insert includes a tapered second portion opposite the cylindrical first portion, the tapered second portion having a first end diameter that is substantially the same size as the outer diameter; and
the step of inserting the inserts includes contacting the tapered second portion on each of the inserts with the end of the plurality of tubes.

4. The method of claim 1 , further comprising inserting the cable or chain into the plurality of pipes before inserting the plurality of tubes into the plurality of pipes.
