Pneumatic suspended heating device for high-temperature radiation characteristic measurement in particle phase change process

The invention discloses a pneumatic suspended heating device for high-temperature radiation characteristic measurement in the particle phase change process. Laser light emitted by a first laser directly irradiates an experimental sample which is disposed over a nozzle of a spray pipe, the spray pipe is mounted on the upper surface of a base, a gas intake pipe joint, a water intake pipe joint and a water outtake pipe joint are arranged on one side face of the base, the gas intake pipe joint is connected with one end of an insulation pipe, an airflow passage is arranged inside the base, the nozzle of the spray pipe is communicated with the insulation pipe through the airflow passage, the other end of the insulation pipe is connected with a linear gas heater, a window is arranged on the lower surface of the base and provided with a lens over, a lens is embedded in the lens cover to cover the window, and laser light emitted by a second laser directly irradiates the experimental sample from the position under the experimental sample after being reflected by a second reflecting mirror. The pneumatic suspended heating device has the advantages that materials are heated by the dual lasers, and temperature gradient of the upper and lower portions of the experimental materials is reduced effectively.
