Increasing production capacity by enhancing the performance of wet Cooling Towers
Wet cooling towers are considered the most efficient way of cooling process water and this project, run in conjunction with Cooling Parts & Services Ltd ) (cps™, was to enhance the performance of the Concast Wet Cooling Towers application in order to increase the production capacity at the Corus Scunthorpe plant.
The 2H PLASdek™ fill range of different structures and surfaces, was able to match the specific performance requirements as follows:
- PP type pack was chosen in order to increase the heat transfer ability as it is suitable for applications of up to 80˚C and operating temperatures were close to the limit of standard PVC fill.
- Cross Fluted and Vertical fluted pack combination was selected as it addressed both the thermal and low fouling requirements of the project. The combination of angled and channel foils in one pack type promotes intensive mixing of the process water and air flow which delivers efficient heat transfer performance whilst also causing sufficient turbulence within the pack to discourage fouling.
- Vertical channel fill types and splash types for the high fouling application.
- PP also offered additional foil thickness for similar pack weight. Corus appreciated the robustness of the pack which, as well as providing strength during normal operation, will also help reduce the risk of damage when maintenance is carried out in the future.
The Product Profile:
- 1309m3 FKP18.19 Low Fouling Pack in a combination of angled 19mm and vertical 18mm sheets
- 319m3 FKP319
- LEP065 Air Inlet Louvre
Phil Andrews, Managing Director, ) (cps™, stated “As with all refurbishments, the shut down period was fixed and short and therefore support of the installation with 24 hr working was critical. 2H’s professional support ensured that this was achieved firstly by guaranteeing that the pack would be delivered on schedule and secondly by providing professional support for the duration of the project.”
Richard Manning, 2H’s MD said “The construction and operation of Wet Cooling Towers require the use of efficient fill pack, drift eliminators and air inlet louvres, so the choice of pack was key to achieving the process cooling productivity enhancements needed, namely high working temperatures, low fouling and durability. We worked with CPS to review performance data and assist in the design of the optimum mix and configuration of the overall tower fill which consisted of a range of cross fluted and vertical packs – a unique aspect of our design capability which means that different functional types of pack can be custom built to meet the specific project requirements.”
