Abstract:
Purpose. Determination of a functional relationship between the oxygen concentration in the air and meteorological parameters (temperature, pressure, humidity) in open areas.
Methodology. The functional relationship between the oxygen concentration in the air and meteorological parameters is established on the basis of experimental gas laws. Approximating functions of the oxygen volume concentration changing in the air are obtained using mathematical statistics methods. The correction for the determination of the excess air ratio was determined on the basis of the theory of errors. Forecasting the oxygen volume concentration in the air was carried out on the basis of the inverse functional dependence established by means of the discrete Fourier transform.
Findings. Approaches to measuring and predicting the oxygen volume concentration in the air based on meteorological parameters are substantiated.
Originality. A method has been developed for determining the air gas concentration based on meteorological parameters of the environment. The method for determining the excess air ratio as an informative parameter for controlling the fuel combustion has been improved. A method for predicting the oxygen volume concentration in the air based on the discrete Fourier transform is proposed.
Practical value. Technical solutions are proposed and new methods and means of measuring the oxygen volume concentration in the air are developed, including those for improving the accuracy of determining the excess air ratio during the fuel burning in boilers. Also, the obtained results can be applied in different areas of medicine, ecology, agro-industrial sector, and others.
