Abstract:The determination of thermal parameters of the vertical tank for the sinter waste heat recovery is one of the key factors to ensure the engineering implementation of the vertical tank waste heat recovery technology. The insufficient research on the determination of thermal parameters of the sinter waste heat recovery equipment was focused on,and a determination method of thermal parameters of the vertical tank was proposed based on the enthalpy exergy of the outlet heat carrier. With a domestic 2.6 million t/a sintering machine as a research object,suitable thermal parameters of the vertical tank were obtained through the analytical calculation method. The main process of the determination of thermal parameters is summarized as following: Ranges of thermal parameters meet the temperature requirements of the vertical tank process are determined firstly,and the orthogonal test is designed to obtain suitable thermal parameters of the vertical tank. Based on the single tank,thermal parameters of calculation example are that the gas-solid water equivalent is 1.06, the cooling section diameter is 9.0 m,the height diameter ratio is 1.0,and the enthalpy exergy of the outlet heat carrier is 21.33 MW.
