Numerical study of combustion of fuel particles in burning with the introduction of the secondary fuel

Energy is the Foundation for the development and existence of the industrial sector of any country. At present, a significant share in the generation of electricity is coal generation, an important indicator of which is the ecology of production. The estimated reduction of adverse impact of the operation coal-fired power plants on the environment during the application of the technology stage solid fuel burning polyfractional composition. Based on the numerical study of the combustion process, the effect of the introduction of this technology in a steam power boiler with flaring technology is estimated. According to the developed approaches are identified: the level of flue gas temperatures in the furnace chamber height, with the launch of the secondary fuel; indicators of the combustion process at various stages; the trajectory of the particles of burning coal particles; dynamics of changes in the concentration of nitrogen oxides at the height of the furnace, the mechanical incomplete combustion of the fuel and specified values of indicators of efficiency of operation. According to the diffusion-kinetic theory of the combustion modern approaches developed an algorithm, a mathematical model and a computer program for calculating the combustion process of coal fuel of the polyfractional composition taking into account the input of secondary fuel. The model takes into account complex physical and chemical transformations occurring in the process of burning coal fuel, and can be used at the design stage of new installations and upgrading of existing boiler units.
