We have considered some features of combustion products forced convection at internal surfaces smoke exhaust system. The estimated correlation for convective heat transfer coefficient in the appearance of criterion depending model is presented. We have described the construction of the universal experimental installation for the forced convection process research. The results of a full-scale experiment on the forced convection in a channel research are presented. We presented a simplified criterial equation, which describes the forced convection process between the combustion products and the internal surface of the smoke exhaust system duct.
