Targeted fluid delivery system

A kit for modifying a heat exchanger formed from a plurality of tubes arranged in a matrix with a heat transfer fluid transported through interiors of the tubes, the kit comprising in combination:

• means for adding a first fluid to the heat transfer fluid before the heat transfer fluid enters into the interior of the tubes within the matrix;
• and
• means to attach said adding means to the tube matrix,
• said adding means including a plurality of first fluid outlet ports,
• said attaching means including means to secure said ports at a location adjacent the tube matrix in stationary fixed position with respect to the tube matrix.

A kit for modifying a heat exchanger formed from a plurality of tubes arranged in a matrix with a heat transfer fluid transported through interiors of the tubes, the kit comprising, in combination:

• means for adding a first fluid to the heat transfer fluid before the heat transfer fluid enters into the interior of the tubes within the matrix;
• and
• means to attach in fixed relationship said adding means to the tube matrix,
• wherein said matrix of tubes is divided into a plurality of subsets and said adding means includes a means for selectively delivering the first fluid to one said subset of said plurality of subsets of tubes within the tube matrix, said selective delivery means including valve actuation means to deliver the first fluid to different subsets of tubes within the tube matrix;
• whereby the first fluid is delivered into different subsets of the tubes of the tube matrix by manipulation of said valve actuation means,
• wherein said selective delivery means includes a plurality of separate stationary delivery manifolds, each said manifold including means to direct the first fluid into a subset of the tubes of the tube matrix,
• wherein said separate stationary delivery manifolds are configured as tiles having interior passageways therewithin, said interior passageways being in fluid communication with a source of the first fluid,
• whereby the first fluid is directable to said manifold tiles for delivery to a subset of tubes of the tube matrix,
• wherein the heat exchanger modified by said kit includes a waterbox isolating the heat transfer fluid from an exterior environment;
• and
• wherein the kit further includes said valve actuation means interposed between said interior passageways of said manifold tiles and the first fluid source, said valve actuation means disposed outside the waterbox, said valve actuation means having one inlet in fluid communication with the first fluid source and having a plurality of outlets passing through the waterbox and in fluid communication with different said manifold tiles communicating with separate subsets of the tubes of the tube matrix;
• whereby when said valve actuation means is adjusted, the first fluid is directed to only a subset of said manifold tiles and hence to only a subset of the tubes of the tube matrix,
• wherein said manifold tiles include a means for attachment to said tubes, said attachment means including a radially expandable plug having an uncompressed diameter not greater than an interior diameter of the tubes, said plug having a central bore with a bolt oriented therethrough, and having a nut on an end of said bolt remote from a bolt head;
• and a stop plate interposed between said nut and said radially expandable plug, said stop plate having a portion larger than a diameter of the tube to remain outside the tube such that when said nut is tightened upon said bolt, said stop plate and bolt are drawn toward said radially expandable plug causing a diameter of said radially expandable plug to increase and be forced against interior walls of said tubes;
• and
• wherein said manifold tiles include bolt holes therein locatable over said bolt fastenable to said bolt with another nut;
• said bolt head is positioned within a tube of the tube matrix along with said plug such that said stop plate and said nut are exposed outside the tube;
• and
• such that one of said manifold tiles are attachable to the tube matrix by fastening of said manifold tile to said bolt.

A fluid handling system for heat exchange in a power plant and for adding a first fluid to a second fluid, wherein the second fluid is directed from a duct to a plurality of tubes oriented in a matrix and located in a box-like housing, the invention comprising in combination:

• a delivery means for said first fluid interposed between the duct and adjacent the tube matrix within the housing at a location adjacent the tube matrix,
• said delivery means including a first fluid outlet delivering the first fluid into the second fluid, said first fluid outlet oriented to deliver the first fluid at an angle non-parallel to a central axis of the tubes of the matrix, whereby mixing of the first fluid with the second fluid is encouraged;
• and
• means for securing said delivery means to the tube matrix.
