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 reheater. Background technique [0002] Thermoelectric power generation uses the Seebeck effect to convert the thermal energy generated by the temperature difference between high and low temperatures into electrical energy, but the directly generated electrical energy is DC voltage. The power supply can only be supplied after being adjusted by the inverter and the voltage stabilizer protector in turn. [0003] like Figure 5 As shown, the figure is a schematic structural diagram of an existing power plant to generate electricity based on the Rankine cycle principle. Conventional fossil fuels are usually inefficient in power generation, and a large amount of energy loss exists in the boiler section in the Rankine cycle of t...

AI Technical Summary

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 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 450-700°C in the reheater area. According to the second law of thermodynamics, the greater the heat transfer temperature difference, the greater the irreversible loss. The greater the loss, the worse the economy of the unit
