4, Detailed parameters

The instrument is mainly composed of control box and combustion box.

1. Combustion chamber: stainless steel.

2. Combustion system: burner: the inner diameter of burner is ￠ 9.5 & plusmn; 0.5mm, equipped with needle valve, which is convenient to adjust the gas flow rate and flame height. The flame height can be adjusted from 20 mm to 100 mm according to the standard requirements. It is equipped with flame height gauge (38 mm / 22 mm) and methane pressure regulating system. It is equipped with electronic igniter, which can ignite automatically.

3. Timing system: timer: three, respectively, for the application of flame timer, combustion timer, flame delay timer.

Timer setting: 099.99/s/m/h, can be set at will.

4. Test fixture: made of U-shaped corrosion-resistant metal plate, equipped with ash box.

5. Observation window: the front of the combustion chamber is an observation window made of heat-resistant tempered glass, which is convenient to observe the combustion changes during combustion.
