• Steel structure box body, inner wall is stainless steel plate, steel plate thickness of 3mm, in the upper furnace door and the rear wall of the combustion chamber is provided with an observation window. The interlayer is filled with thermal insulation material, and the walls of the combustion chamber have good thermal insulation

  
  

• The combustion chamber is composed of furnace body and furnace body cabinet, and its inner diameter size is 800*800*2000mm. The door is divided into two layers, which are connected with the furnace body with a chain. Install toughened glass on the furnace door to check the combustion state of the sample.

  
  

• The air stabilizer layer is a square frame made of Angle steel, which is arranged at the bottom of the square under the burner. 304 stainless steel wire mesh is laid on the bottom of the square, and multilayer glass fiber felt is laid on it

  
  

• The burner is made of stainless steel square, 1000mm away from the bottom of the furnace, and the flame nozzle is installed above

  
  

• It is equipped with high-precision MFC to control the feed of gas and air, and can digitally control and display the real-time flow value through the upper computer and mix through venturi, so that the burner can provide a stable fire source

  
  

• Equipped with pipe blower, equipped with stainless steel air supply pipe, to transport combustion air to the furnace body

  
  

• Equipped with differential pressure sensor and pitot tube to confirm wind speed control air intake

  
  

• The flue of the combustion shaft furnace is a square passage with a cross-sectional area of 500mm×500mm and located at the top of the furnace. The lower part is connected with the combustion chamber, and the upper part is connected with the external chimney

  
  

• Equipped with smoke exhaust fan, and through the inverter control smoke exhaust air volume to change the pressure in the furnace

  
  

• The pressure in the furnace is measured by imported Setra sensor, the data is stable and reliable

  
  

• The sample support is a rectangular frame with a height of 1000mm. Around the frame are screws for adjusting the safety distance of the sample. The frame is made of stainless steel

  
  

• American OMEGA K type armored thermocouple with diameter of 1.5mm was used for temperature measurement.

  
  

• Computer + professional software control, guided operation, convenient, safe and reliable operation, can automatically adjust the test conditions, display the various states in the test, to record the test results; Computer configuration can be selected according to actual requirements
