Heat recovery from tunnel heat exchanger process

摘要

The method involves controlling circulating quantity of coolant and the temperature of the coolant. The circulating quantity and the temperature of the coolant are measured and controlled based on the comparison of measured value with predefined parameters, so as to optimize the thermal yield of a heat exchanger (3). The predefined parameters include the operating performance of the tunnel re-cooling apparatus (1). The predefined parameters comprise the type of product. The readjustment and re-entry of the predefined parameters are performed. An independent claim is included for a tunnel re-cooling apparatus.
