Problems solved by technology

However, in conventional flat-plate burners, the gas fuel used is relatively single, and when the heat generated by gas combustion is less than the heat lost by the tube wall, quenching occurs
At the same time, due to the short residence time of the gas in the burner, the combustion will be insufficient and unstable.

Abstract

The invention provides a liquid fuel burning micro-combustor applied to a micro-thermal photoelectric system. The micro-combustor comprises feeding channels and a combustion chamber, wherein the feeding channels are positioned at inlets of the combustion chamber and comprise a gas fuel channel and a liquid fuel channel, the gas fuel channel surrounds the liquid fuel channel, a first igniter is arranged in the middle of the gas fuel channel, a second igniter is arranged at the junction of the liquid fuel channel and the combustion chamber, and the gas fuel channel is ignited through the first igniter for preheating the liquid fuel channel. By using the gas and liquid dual fuel inlets, two fuels are effectively and fully premixed, so that the combustion is more stable, by using the gas and liquid dual fuels, the energy conversion efficiency is improved, so that the combustion is more sufficient, and meanwhile, the emission of pollutants such as NOX in the combustion product is reduced.

Description

technical field [0001] The invention relates to the technical field of micro-scale thermal photoelectric energy conversion, in particular to a micro burner for burning liquid fuel applied to a micro thermal photoelectric system. Background technique [0002] Under the strong impetus of micromachining technology, continuous breakthroughs have been made in the research and development of micromechanical and electromechanical products, but the power supply part has not made great progress, resulting in the complete microelectromechanical system (MEMS) being too large, too heavy or Cannot work for a long time, which has become the bottleneck of MEMS development. However, the proposal of a combustion-based micro-power device is expected to solve this problem well, so it has attracted the attention of many scholars. [0003] As a typical micro-power device, the micro-thermal photoelectric system uses the heat energy generated by the combustion of hydrocarbon fuel in the micro-com...
