The mathematical model of coke formation process in a biofuel flow in warmed channels of the aviation engine heat exchanger in the form of equations system of heat transfer and diffusion for the dissolved oxygen, middle products, high molecular connections and for particles of adjournment in margin layer is presented in the article. Results of calculation of characteristics of coke formation process depending on external conditions of process of fuel flow are given.
