Gas sampling probe, the gas sampling probe is in flue, and the gas sampling probe is sequentially connected aspiration pump, mistake
Filter device, cooling de-watering device, dehydrating unit, part flow arrangement, Demarcate Gas device, spinner flowmeter, gas analyser.
Further, the filter includes first level filtering device and two-stage filter.
Further, the gas analyser is 02Analyzer, C02Analyzer, C0 analyzers.
Further, the normalizing gas in the Demarcate Gas device is nitrogen.
Further, the spinner count number is 3.
Further, the gas collector is cross.
Further, the flue is provided with heat traced pipeline, for keeping sample temperature degree.
Relative to prior art, a kind of burning gases concentration detection system described in the utility model has the advantage that：
To carry out quantitative measurment to the oxygen demand and carbon monoxide in fire in tunnel flue gas, three kinds of gas concentrations of carbon dioxide and divide
Analysis, helps to understand tunnel fire hazard characteristic.
