CALCULATION METHODS FOR PRODUCTS OF COMBUSTION OF CHEMICAL FUEL THERMOPHYSICAL PROPERTIES O. В. Barysheva Kazan State Architecturе-Buildind University, Russia, 420043, Kazan, Green str., 1, [email protected] Created and developed algorithms and programs of calculation of private derivatives of composition on a temperature, necessary for the calculation of heat conductivity and heat capacity of products of combustion. At consideration of physical and chemical processes of burning, flowings in a combustion chamber power station it is necessary to take into account the transfer of heat because of dissociation of matters is underlines actuality of work. Introduction to the calculation formulas of private derivatives of composition on a temperature [1] is produced the account of warmth of chemical reactions. Two variants of calculation of private derivatives are offered a calculation is produced without attachment to concrete power station: 1. local thermodynamics equilibrium is examined; 2. private derivatives of composition on a temperature are from the system of equalizations of dissociation and equality the zero of general stream of matters both in the free and in dependent state. Advantage of such approach is in the following. If for the calculation of constituent of coefficient of heat conductivity to apply private derivatives, found from the system of equalizations of chemical equilibrium, on occasion there is possibility of receipt of result, not having physical explanation, that subzero value of constituent of coefficient of heat conductivity, taking into account the transfer of heat. Thus, the change of composition on a temperature is described the different values of private derivatives and it have influence on end-point resoult: thermodynamics and thermophysical properties. To the questions of influence of methods of calculation on thermodynamics and thermophysical parameters, to determination of scopes of applicability of different methods of calculation, near the calculation of major parameters the conducted researches are devoted application of the alternative going.
