The analysis was performed concerning the existing normative methods of calculation of the parameters of thermal effect in case of accidents at hazardous production facilities with ignition of hydrocarbon gas. The verified model is proposed for defining the geometrical characteristics of high-speed stream of flare taking into consideration gas parameters. Analystical relationships for defining angular coefficients of solar radiation from optional-oriented elevated flare are given.
It is shown that the normative methods of assessment of thermal exposure, existing currently at accidents with ignition of gas, require correction. At its carrying out there will be useful proposed in the Article verified physical models of flare of the supersonic stream gas and the methods of calculation of thermal streams on the earth surface from a flame of the cylindrical form.
