Problems solved by technology

[0016] However, when the present invention uses different types of fuels, the process steps of changing the filter screens with different mesh numbers are more cumbersome, and a uniform velocity distribution cannot be formed in time, which is very inconvenient in actual use. Therefore, the practicability of the device is still To be further improved

Embodiment Construction

[0037] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Such as figure 1 As shown, a micro-burner for visualization research is characterized in that it includes a base 1, a boss 2, a threaded hole 3, a burner 4, a filter screen 6 and a groove 7;

[0039] The lower end of the base 1 is a gas inlet 8, and the other end is a boss 2;

[0040] The upper end of the burner 4 is an air outlet 5 installed on the base 1 through a threaded hole 3 and connected;

[0041] A filter screen 6 is arranged between the boss 2 and the groove 7.

[0042] The working principle of a micro-burner for visualization research according to the present invention is: during operation, hydrocarbon fuel and oxidant enter from the intake port of the base, and are mixed inside, and then pass through filters of differen...

Abstract

The invention discloses a micro-combustor for visualization research. The micro-combustor is characterized in that a base, a boss, thread holes, combustors, an air outlet, a plurality of filter screens, a groove and an air inlet are included; the air inlet is formed in the lower end of the base; fuel and an oxidizer are mixed inside the air inlet; the boss is arranged at the other end of the base;the combustors are installed on the base to form communication through the thread holes; the filter screens with different mesh numbers are arranged between the boss and the groove. In considerationof materials of the combustors being quartz glass, the morphological structure of flames and the transition law of unstable flames in the combustion process can be observed intuitively, and certain visualization research value is achieved.

Description

Technical field [0001] The invention relates to the field of micro-scale combustion, in particular to a micro-burner used for visualization research. Background technique [0002] With the development of micromachining technology, the Micro Electro-Mechanical System (MEMS for short), which is characterized by a small size, has become a research hotspot in the world. MEMS is a device that integrates micro sensors, micro actuators, micro circuits and micro energy sources. If MEMS wants to take advantage of its miniaturization, it needs a tiny power system to provide power and power, which has prompted the rapid development of power MEMS. [0003] As the core component of the micro power system, the micro burner plays a key role in providing energy for the system. Hydrocarbon fuels and oxidizers are combusted inside, converting the chemical energy of the fuel into heat energy, so as to perform subsequent performance output. Therefore, how to improve the combustion process of micro-...
