1. The box body of the test device is made of stainless steel plate (table 1.5mm)
2. Designed and manufactured with all stainless steel materials, and has six moving parts: (1)Y moving (2) X moving (3) Z moving (4) Y sliding (5) rotating about Z axis (6) the burner around the x-direction -450~+450.
3. Adopts the manual method to realize the relative movement of X, Y and Z between the test piece and the burner, as well as the quadrature rotation around the Z axis, which can easily determine the relative position between the test piece and the burner
4. Equipped with a positioning switch and beeping and ringing to facilitate the timing and end of the combustion test.
5. Equipped with manual adjustable damper device. Turn the torque to the right to open the damper, and reduce the torque.When using power ventilation, adjust the size of the damper to the air velocity of the tuyere to be 0.7 ± 0.1m/SEC, and tighten the lock nut.
