Abstract:

This paper introduced a new technology of waste heat recovery from gas primary cooler，by which chilled water can be prepared by recovering the waste heat from the upper stage circulating water of the primary cooler in summer and heating water can be heated up by recovering the waste heat from the medium stage circulating water of the primary cooler in winter so that the waste heat from the gas primary cooler can be fully utilized，energy consumption can be saved and environment can be improved.
