This article studies the design of a temperature difference based power generation device for power plant boiler reheaters. The power generation device is located on a boiler reheater with the arrangement of the hot end of the temperature difference power generation unit in contact with the hot flue gas of the vertical flue of the boiler, and the cold end in contact with the boiler reheater. The power generation can be realized by utilizing the temperature difference between the two ends and the Seebeck effect of thermoelectric materials. The design principles, design models and implementation methods are systematically illustrated in detail. Compared with existing power generation technology, temperature difference based technology has the advantages of improving power generation efficiency, heat absorption rate, and heat transfer efficiency. Also, the development prospects and economic values of the temperature difference based power generation device are expected to be very huge in the future.
