Manual fin cleaning system / Stationary nozzle header
Stationary/Fixed nozzle header moved to entire length of ACC by manual.
The primary purpose of a fin cleaning system is to remove dirt, dust, debris and other contaminants that can accumulate on the fins over time, thereby improving the overall efficiency and performance of the equipment. Here are the key components and features of a typical fin cleaning system.
The main parts of this system consists of three namely nozzle header, moving ladder arrangement and rails.
- Nozzle header It’s a three fixed nozzle headers each covering 1/3rd of bundle height. Each nozzle header consists of bunch of nozzles (Usually 15 to 25 numbers). Total number of nozzles depends on the high pressure pump output flow. The flow of water to these headers is controlled by three ball/gate valves.
- Moving Ladder 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.
- Rails 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.
Cleaning the finned tube requires just one person to move the ladders from left end to right end.
Fixing of rails, assembling of ladders, nozzle headers fixing and cleaning procedures are mentioned in the O & M manual and provided at the time of erection.
Regular cleaning and maintenance of finned surfaces are essential to maintain the efficiency of air-cooled / fin-fan coolers equipment in all the power generation industries and industrial cooling systems.
