Экспериментальные исследования изменения объемной концентрации кислорода в воздухе и его влияние на процесс горения

The effect of changes the volume oxygen concentration in the air on the combustion process are showed. Suggested the model for calculating the current concentration of oxygen in air depending from the main meteorological parameters – temperature, absolute pressure and relative humidity. Performed the experimental studies of the daily/seasonal changes of volume oxygen concentration in the air on the basis of direct and indirect measurements. Performed a metrological evaluation of results, confirmed the adequacy of the proposal model. Proposed a formula for calculating the air excess ratio based on the current concentration of oxygen in the ai
