Large power transformers such as used at electrical generating plants utilize oil for cooling with the heat removed by air cooled radiators. Several air cooled radiators are removed from the transformers and the oil circulated through plate heat exchangers which provide a heat transfer path to a fluid cooling medium such as water. Flow transducers and electrical temperature sensors may be used to monitor the flow rates of the oil and water, and the temperature of the oil and water in various parts of the system. These parameters are controlled to maximize the transfer of waste heat from the transformer to the water. The heated water is then utilized to perform useful work. For example, in a power plant having package boilers, the boiler makeup water is preheated with the transformer waste heat thereby reducing the energy requirements of the system.
In an oil-filled power transformer having a plurality of cooling oil inlets and outlets and adapted to permit circulation of cooling oil through the core and coils of said transformer, a cooling and waste heat recovery system comprising:
