Abstract

The invention discloses a combustor with adjustable combustion atmosphere and an experimental method and belongs to the technical field of fuel combustion. The device comprises a combustion chamber, aliquid fuel sample injection mechanism, a powder fuel sample injection mechanism, a powder dispersion mechanism, a blocky fuel lifting platform and a water vapor generation device, fuel combustion experiments in three different states are achieved through the three feeding mechanisms, boron particles can be dispersed through a powder dispersing mechanism in the powder fuel sample feeding mechanism, the falling speed of the boron particles is reduced, the influence of incoming air flow on the ignition and combustion process of the boron particles is reduced, and combustion efficiency is improved; reliable ignition of the boron particles in a relatively dispersed state can be realized. The steam atmosphere is provided through the steam generation device, the steam concentration in the combustor is monitored in real time in cooperation with the humidity sensor, and quantitative regulation and control over the steam concentration in the combustor can be achieved; the combustor is connected with high-pressure gas sources such as nitrogen, oxygen and argon, and the purpose that the concentration and pressure of various atmospheres in the combustor are adjustable is achieved in cooperation with real-time monitoring of the pressure sensor.

Description

technical field [0001] The invention belongs to the technical field of fuel combustion, and in particular relates to a burner with an adjustable combustion atmosphere and an experimental method, which can realize reliable sampling of liquid fuel, powder fuel and block fuel, and can ignite and burn in a high-pressure complex atmosphere. Background technique [0002] Solid propellants are the energy source and working medium source of solid rocket motors. In order to increase the energy of solid propellants, metal powders such as boron powder, magnesium powder, and aluminum powder are often added to solid propellants, which can not only increase the specific impulse of the propellant And density, can also suppress the unstable combustion of propellant. However, the ignition and combustion properties of these metal powders are poor, and it is difficult to achieve efficient combustion of metal powders in propellants. Therefore, it is necessary to study the ignition and combustio...
