FIELD: energy industry.
SUBSTANCE: gas sampling is carried out and the concentration of oxygen in the exhaust gas is determined by processing the information received using the computer. Gas sampling is performed using the sampling device, made of coaxial channels, connected with the end vortex chamber in which a sensor sensitive to oxygen is placed, and the determining of the oxygen concentration is performed by measuring the electromotive intensity of the sensor sensitive to oxygen and the continuous computer processing using the data based on a numerical solving the Nernst equation.
EFFECT: simplifying and improving the reliability of measuring the concentration of oxygen in the exhaust gas of thermal power plant.
