A kind of burner applied in micro-thermal photoelectric system

Abstract

The invention provides a burner applied to a microthermophotovoltaic system. The burner comprises an upper burning chamber portion, an igniter and a lower burning chamber portion; the upper burning chamber portion is adhered with the lower burning chamber portion through a high temperature-resistant adhesive; the cross sections of the upper burning chamber portion and the lower burning chamber portion are rectangular; a tail gas processing area and a porous medium area are arranged in the upper burning chamber portion; the lower burning chamber portion is divided into a plurality of catalytic burning areas by ceramic sheets, one side of the ceramic sheet adjacent to the long edge of the lower burning chamber portion is coated with a catalyst, and the ceramic sheets face the long edge surfaces of the lower burning chamber portion. The igniter is arranged between the upper burning chamber portion and the lower burning chamber portion, and is inserted to the catalytic burning areas. The burner can realize stable and high-efficiency burning of multiple fuels and various limiting conditions in a minimal scale, provides a stable wall surface high temperature, greatly improves the energy utilization rate, and reduces environment pollution.

Description

technical field [0001] The invention relates to the technical field of micro-scale thermal photoelectric energy conversion, in particular to a burner applied to a micro thermal photoelectric system. Background technique [0002] With the increasing demand for micro-electro-mechanical systems and the rapid development of micro-scale processing technology, micro-dynamic mechanical systems have become a current research hotspot. The system is based on the combustion of fuel, and has the characteristics of high energy density (about dozens of times that of conventional lithium batteries) and small size (generally below the millimeter level). As a micro-dynamic mechanical system with no moving parts, the micro-thermal photoelectric system uses the chemical energy released by the combustion of fuel in the burner to convert it into radiant energy on the wall of the burner, and then uses photovoltaic cells to perform photoelectric conversion to generate electrical energy. However, ...
