A cogeneration system of cascaded thermal photovoltaic and thermoelectric combined power generation

Abstract

The invention discloses a cogeneration system of cascade thermal photovoltaic and temperature difference thermoelectric coupled power generation, including a premixing chamber, a combustion chamber, heat radiators and a heat exchanger. The upper end of the pre-mixing chamber is provided with the combustion chamber, and the heat radiators are arranged on the left side and the right side of the combustion chamber. The outer sides of the heat radiators are provided with filters. The outer side of each filter is provided with a thermophotovoltatic cell, and the outer end of the thermophotovoltatic cell is welded with a cooling water sleeve. A temperature difference thermoelectric converter is arranged above the combustion chamber. The heat exchanger is arranged above the temperature difference thermoelectric converter. The system has the function of cogeneration, not only can realize self power supply, but also can provide indoor heating or living hot water, and has a strong practicality. In addition, the thermoelectric conversion efficiency of the system is high, the heat energy generated by combustion can be effectively utilized and the energy can be effectively saved. The invention also has the advantages of simple structure, low production and maintenance cost, and wide applicability.

Description

technical field [0001] The invention relates to a heat and power cogeneration system, in particular to a heat and power cogeneration system in which cascaded thermophotovoltaics and thermoelectricity are combined to generate electricity, and belongs to the technical field of thermoelectricity. Background technique [0002] Modern gas heating systems require the use of electrical equipment (pumps, blowers, controls, etc.) to improve their performance and efficiency, and are therefore dependent on electricity for start-up and operation. However, most of the power supply of the existing gas heating system comes from an external power supply. If the external power supply is interrupted, the heating system cannot work. Moreover, in many remote areas, there is a lack of external power supply that can provide sufficient working power, so that the heating equipment cannot be started. [0003] In order to overcome this defect of the heating system, people have gradually developed mi...

However, most of the power supply of the existing gas heating system comes from an external power supply. If the external power supply is interrupted, the heating system cannot work

Moreover, in many remote areas, there is a lack of external power supply that can provide sufficient working power, resulting in the failure of the heating equipment to start

[0003] In order to overcome this defect of the heating system, people have gradually developed micro-cogeneration equipment suitable for households, such as internal combustion engines, Stirling engines, fuel cells, etc., but these equipment generally have high cost, large noise or large displacement However, the research and development of fuel cells is still in its infancy, and there are still many technical problems to be solved. Therefore, it is urgent to develop a new type of widely applicable household cogeneration system
