We analyzed properties of combustion products in a fire on the base of the basic principles of the heat conduction phenomenological theory. The conditions of taking into account the nonlinearity of the transfer process in solving the energy equation are investigated. We formulated boundary conditions for solving a quasilinear parabolic heat equation taking into account the influence of convective heat and mass transfer processes. The obtained solution is analyzed and the necessary conclusions on the heat impulse propagation in the combustion products are made, in case that they are represented by a non-Newtonian fluid.
