Problems solved by technology

[0008] The thermal analysis method mainly reflects the ignition and combustion characteristics of metal particles indirectly through the thermogravimetric characteristics. The particles are heated in a closed burner, and it is impossible to observe the shape of particles and flames during the ignition and combustion process, and it is difficult to obtain abundant test data.

Abstract

The embodiment of the invention provides a micron-scale metal particle ignition and combustion testing device. The micron-scale metal particle ignition and combustion testing device comprises a metal particle dispersing device, a powder supply thin tube, a high-temperature fuel gas ignition system, an observation system and a particle sampling device, wherein the metal particle dispersing device is positioned under the high-temperature fuel gas ignition system and is connected with the high-temperature fuel gas ignition system through the powder supply thin tube; the observation system is arranged above the high-temperature fuel gas ignition system; the particle sampling device moves above the high-temperature fuel gas ignition system so as to realize sampling. According to the micron-scale metal particle ignition and combustion testing device provided by the invention, a single micron-scale metal particle ignition and combustion state can be directly obtained, meanwhile, a metal particle ignition and combustion environment created by planar flame furnace is closer to an ignition and combustion environment of actual metal particles, and an engineering application value of obtained testing data is high.

Description

technical field [0001] The invention relates to an ignition and combustion test device, in particular to an ignition and combustion test device for micron-sized metal particles. Background technique [0002] In order to improve the performance of the engine, the prior art usually adds high-energy metal additives to the propellant. Adding high-energy metal additives can not only increase the energy density of the propellant and the specific impulse of the engine, but also significantly suppress the unstable combustion of the propulsion system. Therefore, metal additives are widely used in solid propulsion systems. In addition, in the face of increasingly serious energy security issues, people pay more and more attention to the development and utilization of new energy. Compared with hydrogen energy, biofuels, and batteries, metal powder fuel has the characteristics of abundant sources, safe and reliable carrying, high combustion calorific value, and environmental protection...
