Abstract：Objective To performe a research on the recovery and utilization of large amount of waste heat in the operation of
oxygenerator. Methods The heat energy was transfered into the water by connecting the heat exchanger to the Screw type oxygen
generator compressor lubricating oil line, and S7-200 series PLC through temperature-flow Cascade feedback control system was
used to control the waste heat recovery system. Results The effect of waste heat recovery system of this kind of oxygen generator
was good and it had many unique advantages. Conclusion There is a great potential for the waste heat recovery of the oxygen
generator. The method designed in this paper is very suitable for the waste heat recovery and utilization of the oxygen generator.
