Fin Cleaning System for “A” / Inclined Bundle ACC

The primary purpose of the fin cleaning system is to remove dirt, debris, and other contaminants that can accumulate on the fins over time, thereby improving the overall efficiency and performance of the equipment. There are three divisions of fin cleaning system “A” which is Semi automatic, Fully automatic and Manual system. Here are the key components and features of a typical fin cleaning system. The main parts of the system consists of three namely nozzle header, moving ladder arrangement, panel box and rails. It's three headers each covering 1/3rd of bundle height. Each nozzle header consists of a bunch of nozzles (usually 15 to 25 numbers). Total number of nozzles depends on the high pressure pump output flow. The flow of water of these headers is controlled by three balls/gate valves. These three nozzle headers are fixed under the fin cleaning system ladder and the ladder is moving on two rails namely top & bottom rails with use of rollers. The Function of panel box is to sense the top & bottom most position of nozzle header and trigger the motor rotation in opposite direction. After each completion of the cycle, the ladder is moved right or left with the use of a second motor. Both the movements are synchronized by the panel box. Additionally rails are provided for easy movement of ladders. These rails are permanently fixed on the tube bundle by welding or fastening. Alignment of these rails smoothen the movement of ladders.
