A thermal photovoltaic power generation system and method based on liquid fuel porous media combustion

Abstract

The invention discloses a thermal photovoltaic power generation system based on liquid fuel porous medium combustion, comprising a porous medium burner and a thermal photovoltaic cell. The thermal photovoltaic cell is installed on the outer wall of the upper end of the porous medium burner, and fuel preheats a catalytic tube. The double-pipe preheating system composed of the air intake preheating pipe is wound on the outer wall of the thermal photovoltaic cell and the porous medium burner in turn, and then enters the porous medium burner for ignition and combustion, and the thermal photovoltaic cell is connected to the generator. and IV testing systems. The invention adopts the design that the preheating pipe is wound around the outer wall of the burner and the thermal photovoltaic cell, on the one hand, the preheating pipe absorbs the high temperature generated by the reaction of the burner to improve the preheating efficiency of the thermal photovoltaic cell, and also improves the power generation efficiency of the thermal photovoltaic cell; On the other hand, the heat loss of the porous media burner can be reduced.

Description

technical field [0001] The invention belongs to the technical field of thermal photovoltaic power generation, and in particular relates to a thermal photovoltaic power generation system and method based on the combustion of liquid fuel porous media. Background technique [0002] As a new combustion method, porous media combustion is gradually promoted in engineering applications. Compared with traditional combustion methods, porous media burners have the advantages of wide lean combustion limit, high combustion efficiency, uniform wall temperature distribution, and low pollutant emissions. It is through the heat conduction and radiation heat transfer of the porous skeleton, which can make full use of part of the heat generated by the combustion of the premixed gas to transfer from the downstream high temperature zone to the upstream low temperature zone to realize the preheating of fresh fuel. Due to the relatively large porosity of porous media, it has better heat storage c...

Problems solved by technology

my country's biofuels have also achieved further development. At present, biodiesel and ethanol fuels are the two most widely used biofuels. Biofuels have the advantages of diversity, materiality, recyclability and environmental protection. However, the production process of biofuel technology Still need to improve

Compared with ordinary diesel, biofuels have disadvantages such as high viscosity, poor atomization performance and low-temperature fluidity, so it is difficult to ignite biofuels.
