Title of the articleDiffusion flows during combustion of natural gas in the combustion power plants
Abstract.In this work was estimated diffusion of individual substances based on classic formulas of molecular-kinetic theory of gases. They arise due to the change of their concentration at different degrees of dissociation in the presence of a temperature gradient. In this text considered the combustion products of natural gas. For this were show conditions of stoichiometric combustion in the combustion chambers of power plants. Formed in these regions, the products of combustion are strongly dissociated. At the same time, washed moving products of combustion chamber walls of the combustion plant, due to application of different cooling methods have a significantly lower temperature at which the dissociation of the combustion products must be practically absent. Obviously, in the area limited by the temperature of the flow core and wall designs dissociation of combustion products varies and there are gradients of concentrations of individual substances and the corresponding mass flows. These flows have a significant impact on the thermo physical properties of combustion products. Data was obtained on the diffusion flows arising in high-temperature areas combustion power plants.
Keywords.coefficient of binary diffusion, coefficient of generalized diffusion, combustion, power plants, diffusion flow.
