The invention discloses an organizing device for stable combustion of metal powder. The device comprises a gas supply system, a powder supply box and a combustion chamber. The outlet of the air supplysystem is provided with four independent air paths, including a side air inlet air path, a head air inlet air path, a protective gas air path and a fluidized gas air path. The side air inlet air pathis connected with the middle section of the cavity of the combustion chamber, and is used to input air and adjust the air-fuel ratio in the cavity. The head air inlet air path is connected with the head end of the combustion chamber to supplement the air required for ignition in the cavity. The protective gas air path is connected with a plasma igniter and used as the ionized gas source of the plasma igniter. The fluidized gas air path is connected with a powder outlet of a powder feeder, and is used to carry metal powder into the combustion chamber. Using this device, ignition under rich combustion conditions and com
