specific Embodiment 1

[0026] The structure of the miniature internal mixing type catalytic burner in the specific embodiment 1 is as Figure 1 to Figure 6 shown.

[0027] The micro internal mixing catalytic burner is made of single crystal silicon material, including the upper preheating chamber 1, the combustion chamber 2 and the lower preheating chamber 3, the upper and lower preheating chamber 1, the lower preheating chamber 3 and the upper and lower surfaces of the combustion chamber 2 Bonding forms a three-layer structure.

[0028] The inside of the upper preheating chamber 1 and the lower preheating chamber 3 are respectively etched by MEMS processing, and the upper preheating chamber preheating channel 4 and the lower preheating chamber 7 are respectively etched outside the upper preheating chamber and the lower preheating chamber. The upper preheating chamber preheating channel inlet 5 and the lower preheating chamber preheating channel inlet 8 are formed on the surface. The preheating pa...

Abstract

The invented catalytic combustor includes combustion chamber of monocrystal silicon material, upper preheating chamber and lower preheating chamber, its upper and lower surfaces are bonded and formed into three-layer structure; in the upper and lower preheating chambers respectively an etched preheating channel is set, and the combustion chamber interior is successively equipped with mutually-communicated etched premixing channel, combustion zone space and exhausting channel. Its structure is compact and can raise combustion efficiency.

Description

technical field [0001] The invention relates to a combustion device, in particular to a micro internal mixing catalytic burner which mixes fuel gas and oxidant inside the burner. Background technique [0002] Compared with traditional combustion, micro-combustion occurs in a larger scale range. The micro-combustion currently studied generally occurs in a small scale range, and they usually occur in a volume below 1cm3. The energy generated by micro-combustion has a broad application prospect as an energy provider in micro-electromechanical systems, micro-aerospace equipment, personal mobile electronic devices and other devices. Compared with batteries, micro-combustion has the characteristics of energy density dozens of times higher than batteries, low price, stable output voltage, less environmental pollution and convenient fuel addition. [0003] The currently researched micro-combustors can directly output thermal energy or output energy in the form of direct conversion ...
