Methods of calculation of radiation transfer, which are 
used in modeling turbulent diffusion flames, are analyzed. Realization 
of the statistical method (Monte Carlo method) in combination with 
the equations of turbulent flow and combustion of a multicomponent 
mixture which is formed in combustion of hydrocarbons in air is presented. 
A method of calculation of the effective coefficient of absorption 
for a mixture of absorbing gases and soot is described. The effect 
of turbulent temperature fluctuations on the emission of thermal radiation 
is taken into account.
