Abstract

In the paper have been further development a mathematical model, that used the equation of non-stationary thermal conductivity. This model describes the thermal effect of the fire on the readings of the imager. The measurements of temperatures of external structures during fires showed the adequacy of the mathematical model with an error of up to 35%, which indicates the possibility of its use in temperature estimation. It has been experimentally shown that the identification of flames by means of a thermal imager through the double-glazed window at the initial stage of the fire is impossible due to the absorption of infrared radiation. It is only possible to identify a fire while the window is warming. The temperature of glass pack during fires was investigated experimentally. The error on the temperature difference, i.e. the change from the initial temperature, is estimated. As a result, it is found that the error does not exceed 35%.
