A mathematical model of the high-temperature process of 
heat transfer in a cylindrical furnace has been constructed. Based 
on this model, investigations and assessment of the contribution made 
by longitudinal radiation to the process of radiant heat transfer 
in the cylindrical furnace were carried out. It has been established 
that the assumption on the exclusively radial propagation of a radiant 
flux may lead to considerable errors. It is shown that the zone method 
in conjunction with the method of Monte Carlo statistical tests is 
efficient for solving the problem of radiative heat transfer.
