Problems solved by technology
Traditional fossil fuels are usually very inefficient in the process of power generation, and a large amount of energy loss exists in the boiler part in the rankine cycle of the power plant, which is caused by the temperature difference between the high temperature flue gas temperature and the high pressure steam temperature
Because the combustion temperature in the modern coal-fired power plant boiler furnace is as high as 1700°C, and the temperature of the high-temperature and high-pressure heating surface is generally below 600°C, the temperature difference between the smoke temperature and the working fluid in the heating surface in different areas of the furnace is as high as 1000°C. There is also a temperature difference of 500-750°C in the superheater area. According to the second law of thermodynamics, the larger the heat transfer temperature difference, the greater the irreversible loss. The greater the loss, the worse the economy of the unit

Description
technical field [0001] The invention relates to the technical field of heat transfer enhancement and energy saving and emission reduction, in particular to a thermoelectric power generation energy storage and power transmission system applied to a boiler superheater. Background technique [0002] Thermoelectric power generation uses the Seebeck effect to convert the heat energy generated by the temperature difference between high temperature and low temperature into electric energy, but the electric energy directly generated is DC voltage. If it is stored, it needs to be adjusted by a voltage stabilizer protector before it can be stored; if it is used for transmission, it needs The power supply can only be supplied after being adjusted by the inverter and the voltage regulator protector in turn. [0003] Such as Figure 5 As shown, the picture is a structural schematic diagram of an existing power plant generating power based on the Rankine cycle principle. Conventional fos...
