Embodiment 2

[0065] like Figure 12 As shown, in this embodiment, the combustion device 2 is a turbulent flow burner 203, and the turbulent flow burner 203 includes a turbulent flow burner outer wall tube 203-1, and the inner wall of the turbulent flow burner outer wall tube 203-1 is provided with a device that can make the air flow turbulent. In order to form turbofan blades 203-2 of turbulent flame, the middle part of each turbofan blade 203-2 is fixed to the central axis.

[0066] The ignition process of the metal powder in the turbulent burner 203 is the same as that of the laminar burner 201, the difference is that the metal powder burns in the turbulent burner 203 to produce a turbulent flame.

Abstract

The invention discloses a metal powder combustion device. The metal powder combustion device comprises a flow guide pipe, a combustion device is arranged at the top of the flow guide pipe, and a metal powder fluidization conveying device is arranged at the bottom of the flow guide pipe. The combustion device is a laminar flow combustor or a turbulent flow combustor. The metal powder fluidization conveying device comprises a powder storage device, a through powder storage cavity is formed in the powder storage device, a piston capable of moving up and down is arranged in the powder storage cavity, a piston rod at the bottom of the piston is connected with a telescopic driving device, and a fluidizer is arranged at the top of the powder storage device. A through fluidization cavity is formed in the fluidizer. According to the combustion device, good experimental equipment is provided for studying metal powder, the characteristics of laminar flames can be studied, the characteristics of turbulent flames can further be studied with the help of the combustion device, and a foundation is laid for further studying the combustion phenomenon of metal powder fuel.

Description

technical field [0001] The invention relates to the field of gas phase laminar flow and turbulent combustion of powder fuel, in particular to a combustion device for obtaining fuel gas phase laminar flow, turbulent flame propagation speed, flame shape and combustion product distribution by burning metal powder. Background technique [0002] In recent years, countries have developed rapidly in the military field, especially in the research of solid and liquid engines. Not enough, so some experts from various countries proposed a new concept engine-metal powder engine. This engine uses pure metal powder as fuel, which combines the advantages of liquid engine and solid engine, and occupies an irreplaceable position in the future aerospace field, and metal powder fuel (Mg, Al, Be, B, etc.) is a new type of fuel , its high calorific value and high density make the propellant added with metal particles can effectively improve the specific impulse of the engine, which is widely us...
