Abstract
A targeted fluid delivery system (110) is provided for delivering a treatment fluid (F) into tubes (I) of a tube and shell type heat exchanger such as in a condenser (C), typically used in a power plant. The system (110) targets the treatment fluid (F) delivery to separate regions (R) of tubes (I) such that the concentration of the treatment fluid (F) within the tubes (I) of the targeted region (R) is greater than a concentration of the treatment fluid (F) upon mixing with water from other tubes (I) outside of the targeted region (R) at an outlet (O). The system (110) includes a plurality of manifold tiles (160) oriented in fixed relationship to a tubesheet (100) of the condenser (C) at an inlet thereof such that the manifold tiles (160) are rigidly held in place, but do not block the tubes (I) of the condenser (C). The treatment fluid (F) is delivered to the tubes (I) through injectors (180) in the manifold tiles (160). The treatment fluid (F) is delivered to the manifold tiles (160) through fluid conduits (40) which pass through a waterbox (W) of the condenser (C). The fluid conduits (40) are coupled to a control valve (30) which allows the treatment fluid (F) to be directed to i…
