- The system automatically fires and records relevant experimental
data;
- Independent movable timing display platform.
- 10kV spark igniter, equipped with a safe cease-fire device.Fire
fighting and drainage system design.
- Bipolar gas flow valve control system;Avoid leakage of air in the
system caused by malfunction of solenoid valve, which leads to
explosion risk;
- Stair design, convenient exhaust pipe maintenance.
Gas sampling system:
1. High-precision patent design sampling system;Ensure the sampling
gas entering the gas analyzer is stable and free from
impurities;Make the analysis result of analyzer more accurate;
2. Including particle filter;
3. Cold well: compressor principle refrigeration system;Gas
sampling 0 ~ 5 ºC temperature control;
4. Air suction pump: provide gas sampling power source;
5. Drying cylinder;Oxygen and nitrogen dioxide were respectively
analyzed for air drying and impurities removal.
6. High precision ball valve;Open and close the air circuit;
7. Flow controller.
Gas analyzer:
1. Simultaneously analyze oxygen consumption, carbon monoxide and
carbon dioxide production rate.
2. The resolution of the gas analyzer is: oxygen 0~25%, carbon
monoxide 0~1%, and carbon dioxide 0~10%, respectively.
3. Set by-pass for quick response.
4. Data collection system: one set of dedicated collection system
