Introduction The Combustible Gas Burning Rate Test Apparatus is developed according to the requirements of UL 9540A and the standard of ISO 871 Appendix C. The burning rate of combustible gas in the vertical glass tube and the relevant auxiliary parameters are recorded by the camera to measure the burning rate of combustible gas. The Combustible Gas Burning Rate Test Apparatus is mainly composed of combustion tube, ignition system, camera system, gas supply system and waste gas treatment system
Technical specifications 1. Combustion tube: made of quartz glass, with inner diameter of 40mm and length of 1.2m; 2. Ignition system: the ignition system is installed at the bottom of the combustion tube, and the ignition electrode is made of tungsten with a diameter of 1mm, inserted at both sides of the bottom, with a spacing of 6.4mm; 3. Camera system: high-speed industrial camera system is used to record the flame spread process, and special flame graphic analysis software is used to calculate the flame height; 4. Air supply system: The air supply system consists of an air receiver, a vacuum pump, and a pressure gauge. It is equipped with a mixing container and a magnetic stirrer to make the test sample gas evenly mixed; 5. Exhaust gas treatment system: the tail end of the combustion pipe is connected with the expansion container and the gas washer; 6 Control and detection system: computer system virtual instrument test platform, manual and automatic control modes.
