Abstract The waste heat recovery and utilization in sintering process is one of the means to decrease the energy consumption in sintering process. The current situations of waste heat recovery and utilization in sintering process at home and abroad are summarized, and the shortage existing in China is indicated. The power generation process of waste heat recovery and utilization for sinter in vertical tank and grade recovery and cascade utilization of waste heat from sintering process and are expounded emphatically from the perspective of process flow and technical features. The basic idea of the integrated process of waste heat recovery and desulfurization and denitration from sintering exhaust gas is given. It is pointed out that grade recovery and cascade utilization technology of waste heat from sintering process should be promoted actively, power generation process of waste heat recovery and utilization for sinter in vertical tank should be developed rapidly, and the concept of the integrated process of waste heat recovery and desulfurization and denitration from sintering exhaust gas should be deeply advocated so as to lay a technical foundation for China’s energy saving and emission reduction in sintering process.
