Abstract: A cleaning ball with a naturally derived material bonded to a surface of the cleaning ball for a condenser in a power plant is capable of performing efficient cleaning, and even if the material bonded to the surface of the ball is discharged to the ocean, the material does not cause damages to a marine environment. The cleaning ball includes a sponge rubber ball configured to deform and clean a heat transfer tube of the condenser; and a skin layer including crushed sand bonded to a surface of the sponge rubber ball. The crushed sand comprises sandstone containing granite particles, and the crushed sand has a particle size between 0.05 mm and 2.00 mm, and the skin layer is formed in concave and convex shapes on a non-deformed shape of the sponge rubber ball, and is configured to deform corresponding to deformation of the sponge rubber ball.

Abstract: The efficiency of projectile tube cleaning in multitube heat exchangers is greatly enhanced by the use of two or more nozzles for pressurized water or other liquid held by a bracket in parallel orientation a distance apart that equals the distance apart of the tubes. A pneumatic control system enables the simultaneous activation of two or more pressurized water valves so that two or more tubes can be scraped clean at once. Large heat exchangers and condensers having ordered arrays of thousands of parallel tubes can be cleaned by selecting a number of tubes for deposition of cleaning projectiles, repeatedly projecting two or more of the projectiles simultaneously, and immediately moving on to another set of tubes; then repeating the process with another selected number of tubes.

Abstract: A pumping unit is provided that allows at least four passes to be made simultaneously with a single pumping unit. A single engine is used to drive two pumps, each connected into separate pumping circuits. Fluid flow in each of the pumping circuits is controlled by respective flow control elements on the pumping circuits, as for example a variable flow valve. Two engines may thus be used to drive four pumps.
