Abstract
Systems and methods for cleaning a heat recovery steam generator system including tubes and fins associated therewith using deep cleaning alignment equipment are described. The deep cleaning alignment equipment primarily includes at least one wedge and at least one wand. The wedge may be an elongate wedge configured to maximize the surface area that contacts the tubes and fins, which in turn minimizes the amount of stress about any specific point of the tubes or the fins. Additionally, the wedge may be made of a variety of different materials. The wedge may include multiple pieces that can be releasably secured together. The wedge may also have at least one opening formed therein to assist in removal of the wedge from the system.
Claims20
A deep cleaning alignment equipment used to clean a heat recovery steam generator system including a plurality of metallic tubes, wherein each of the plurality of tubes includes a base with a plurality of fins extending outwardly from the base, the deep cleaning alignment equipment comprising:
- an elongate wedge with a width, a length, and a height, and a least one opening extending through the width, wherein the wedge is configured to contact and spread the plurality of tubes and the plurality of fins to form a channel therebetween;
- and
- a wand configured to spray one of a liquid or a gas about the heat recovery steam generator system;
- wherein the elongate wedge contacts the plurality of tubes and the plurality of fins about an extended surface area to minimize a stress force between the wedge and the plurality tubes and the plurality of fins;
- and
- wherein the wand is removably insertable into the channel.
A deep cleaning alignment equipment used to clean a heat recovery steam generator system including a plurality of metallic tubes, wherein each of the plurality of tubes includes a base with a plurality of fins extending outwardly from the base, the deep cleaning alignment equipment comprising:
- a composite wedge configured to contact and spread the plurality of tubes and fins to form a channel therebetween and having a first piece and a second piece releasably secured to the first piece;
- and
- a wand configured to spray one of a liquid or a gas about the heat recovery steam generator system;
- wherein the composite wedge is made of a softer material than the metallic material of the plurality of tubes;
- and
- wherein the wand is removably insertable into the channel.
A method of using a deep cleaning alignment equipment to clean a heat recovery steam generator system including a plurality of metallic tubes, the method comprising the steps of:
- inserting a wedge having a width, a length, and a height, between the plurality of tubes to spread the plurality of tubes to form a channel therebetween;
- inserting a wand into the channel;
- spraying a liquid or a gas through the wand to clean the plurality of tubes;
- and
- removing the wedge from the plurality of tubes;
- wherein the elongate wedge contacts the plurality of tubes about an extended surface area to minimize a stress force between the wedge and the plurality of tubes;
- and
- wherein the composite is a softer material than the metallic material of the plurality of tubes.
