Product Description

ISO817 Annex C Li-ion Battery Thermal Runaway Venting Gas Burning Velocity Tester

Introduction:
The Gas Burning Velocity Tester, by ISO 817 Annex C, is used to measure the burning velocity of flammable gas with air mixed, such as refrigerants, and li-ion battery thermal runaway venting gas, by testing on synthetically replicated gas.

The flammable gas is pre-mixed with air in a tank, and the homogeneous flammable gas-air mixture is introduced to the 1,200mm glass tube with an internal diameter of 40mm and is ignited with the electrodes mounted at the bottom position of the glass tube. The flame will propagate from the lower to the upper end with a constant propagation speed at the flame front. The flame propagation inside the tube is recorded using a high-speed camera and the images are then transmitted to the computer for measuring the flame propagation speed and calculating the flame front area. The flammable gas's Burning Velocity (Su) is obtained by dividing the consumed mixture volume by the frame surface area.


The Gas Burning Velocity Tester consists of:

• High-temperature resistance burning tube, diameter of 40mm, length of 1200mm, pressure resistance better than 0.1MPa.
• 10L Pre-mix chamber, with a pressure resistance of not less than 1 MPa.
• Pressure measurement system, measuring range of -0.1 to 0.3MPa, accuracy better than 0.05% F.S.
• Equips with a pressure relief port device and a special solenoid valve for gas distribution, with a solenoid valve with a pressure resistance of not less than 1.6Mpa and a response speed of not less than 10ms.
• K-type insulated thermocouples, diameter of 1.6mm.
• Ignition system, equipped with 2 ignition needles and an ignition transformer.
• Vacuum pump, capacity no less than 1L/s, used for venting air from the chamber.
• Operation software, function includes gas mixture, gas fill, ignition, and camera activation.
• Automatic program for gas-air mixture preparation in specific concentrations.
• Flame area calculation software, auto calculates the cross-section area of the flame base (af) and flame surface area (Af).
• High-speed camera, auto-triggered by the software.
• Compact physical size, low weight, and high light sensitivity allow use in limited space.
• The system captures at a speed of not less than 1,000 fps at full frame resolution conditions.
• The system captures at a speed of not less than 70,000 fps at 1280 x 8-pixel resolution conditions.
• Minimum exposure time up to 1.0μs.
• The system has a pixel size of 14.6μm and a dynamic range of 60 dB.
