· Facts The flow rate through a cooling tower in a typical 700 MW power plant is about 315,000 gal/min. Cooling towers have 95% efficiency, losing only 5% of circulating water to evaporation. Power consumption is minimal due to few moving parts. Cooling
Cooling of Transformer is the process by which heat generated in the transformer is dissipated or treated to the safe value. This is achieved by various cooling methods of transformer available. The major factor for the generation of heat in the transformer is the various losses like hysteresis, eddy current, iron, and copper loss.

· Types of cooling Even though all thermoelectric plants use water to generate steam for electricity generation, not all plant cooling systems use water. There are three main methods of cooling: Once-through systems take water from nearby sources (e.g., rivers, lakes, aquifers, or the ocean), circulate it through pipes to absorb heat from the steam in systems called condensers, and discharge …

· Various corrosion inhibitors are added to cooling water systems to control the rate of corrosion on mild steel, copper and copper alloys, stainless steel, galvanized steel, and aluminum. Since some inhibitors are more effective in controlling corrosion of a particular metal than others, the corrosion control program should be tailored to the system metallurgy.
