Abstract
The spare parts standardization without excessively sacrificing energy efficiency may reduce the maintenance costs of components in different geothermal power plants of the same company. This strategy may apply to the blades of the fan used in mechanical draft cooling towers, which usually come in different sizes and are numerous. The case study taken as a reference is a standardized blade, designed for a fan diameter of 8.6 m, used in a 9.2 m diameter fan. The results indicated a decrease in efficiency for the fan with standard blades. Nevertheless, some appendices proved to be effective in limiting the efficiency loss.File in questo prodotto:
