Domestic wood as the building material for cooling towers

Most industrial production processes need cooling water to operate efficiently and safely. Refineries, steel mills, petrochemical manufacturing plants, electric utilities and paper mills all rely heavily on equipment or processes that require efficient temperature control. Cooling water system control these temperatures by transferring heat from hot process fluids into cooling water. As this happens, the cooling water itself gets hot before reuse it must either be cooled or replenished by a fresh supply of cold water. The aim of this study was utilizing domestic wood in cooling towers structure. For this purpose, five wood species include: hornbeam, oak, alder, poplar and eldar pine different regions with different climate, include: power plant Montazer- Ghaem near Karaj, power plant Loshan north of Iran, power plant Dorcheh Esfahan in center of Iran and petrochemical manufacturing plants Bandar-Emam from south of Iran, were selected. Sampling were conducted and treated with CCA. All samples were put in the cooling towers and were tested during the study period. (Mechanical tests such as specific gravity, static bending, compression parallel to grain and hardness). Based on this study, the mechanical properties of these species during last four years were done. At the fifth year, there werent any virtual damages,while significant difference was achieved in terms of mechanical properties. Among the wood species, poplar and eldar pine had minimum mechanical degradation and that pinus eldarica had better quality than populus species.
