Abstract:In response to the call of the national energy saving, it has been important corrective measures for many domestic power plants to reduce boiler flue gas temperature and recycle waste heat,whereby low temperature corrosion resistant materials are put forward higher requirements.Regarding this situation,studies are conducted on several low temperature corrosion resistant materials.The results show that Teflon tubing and ZS1041 anti corrosion coating are suitable low temperature corrosion resistant materials with good corrosion resistance.They are appropriate for power plant boiler flue gas heat recovery,which can achieve energy conservation requirements to a greater extent and improve the overall economic benefits of the plant.
