Abstract

The invention provides a micro diffuse type combustion apparatus for a micro-thermphotoelectric system. The micro diffuse type combustion apparatus for the micro-thermphotoelectric system comprises an ignition device, an external sleeve, an internal sleeve and an upper panel, wherein the internal sleeve is positioned in the external sleeve; the upper panel is arranged at the top end of the external sleeve; the internal sleeve is a flared structure with big lower end; the lower end of the internal sleeve is provided with a porous bottom plate; the circumferential wall of the lower part of the internal sleeve; the interior of the internal sleeve is a preheating premixing chamber; a combustion chamber is formed between the internal sleeve and the external sleeve; the preheating premixing chamber is communicated with the combustion chamber through a porous wall and the porous bottom plate; and a gas exhaust opening, an air inlet and a fuel gas inlet are formed in the upper panel. According to the invention, as air enters the porous material from various surfaces, a temperature field is uniform and the combustion is enhanced to increase the device power; through the adoption of special combustion chamber wall surface design, heat obtained by the whole wall surface is much and uniform; the micro diffuse type combustion apparatus can stably respond to fine air inlet pulsation and combustion pulsation; and meanwhile, through the adoption of the porous material with reducing aperture, tempering and backflow problems of the porous material are also avoided.

Description

technical field [0001] The invention relates to a micro-combustor suitable for a micro-thermo-photoelectric system and a micro-thermo-electric system, in particular to a micro-diffused combustion device for a micro-thermo-photoelectric system with a preheating and premixing chamber and a combustion chamber expanding gradually at the same time. Background technique [0002] Micro-scale combustion is proposed with the development of MEMS (micro-electromechanical system) technology, and its combustion is usually below 1cm 3 occurs within the volume. The power generation principle of micro-scale combustion is: micro-scale burners produce high-temperature flue gas to drive heat engines to generate power, or obtain electricity through direct conversion of thermoelectric materials and generate electricity through photoelectric materials. The application fields involve micro-aircraft, micro-satellite propulsion systems, and military individual combat. And many other aspects. Compa...
