某石化厂装置余热回收系统原设计采用热管技术,用烟气的余热来加热入炉空气,但由于存在种种问题,使用效果不理想;针对存在的问题,该套装置进行了改造,改造后的装置采用扰流子翅片管加热,余热回收系统的热效率提高到92%以上,取得明显的经济效益。
The original design of waste heat recovery system of a petrochemical plant waste heat recovery system using heat pipe technology, waste heat to flue gas into the furnace air heating, but due to various problems, the use of results is not satisfactory; for the existing problems, the device has been transformed, transformed The device uses the spoiler heat pipe to heat up the heat recovery efficiency of the waste heat recovery system to more than 92%, and obtains obvious economic benefits.
