Description

technical field [0001] The invention relates to the field of thermoelectric power generation, in particular to a thermoelectric power generation device using medium-high temperature fluid. Background technique [0002] In coal-fired or gas-fired boilers, the flue gas produced by fuel combustion transfers heat to the heating surface in a certain heat transfer method, and a considerable part of the heat is discharged to the atmosphere in the form of smoke exhaust, which will cause a large amount of energy. Among these heat losses, there are heat transfer losses, heat dissipation losses, and smoke exhaust heat losses. If this part of the heat can be used for thermoelectric power generation, it is a good way to save energy. Thermoelectric power generation uses the Seebeck effect The green power generation technology that converts the thermal energy generated by the temperature difference between high temperature and low temperature into electric energy has a good market prospect...
