MATEC Web Conf.

Abstract. The work is devoted to the solution of the issue of environmental protection from harmful emissions of thermal power plants. Mechanisms of nitrogen oxides generation in a low-temperature swirl furnace process are considered. The analysis of the combustion process characteristics influence on the final level of nitrogen oxide concentration in the flue gases of the boilers is presented. Calculations and experimental studies have shown that the method of low-temperature swirl combustion provides a significant reduction in emissions of nitrogen oxides to the atmosphere.

“…The LTV burning opens great opportunities for decreasing overall dimensions of boilers and reducing metal expenditures as a result of increasing intensity of combustion and heat-exchange processes. The application of LTV technology makes it possible to install new boilers into existing building boxes, and in some cases -increase the capacity of an installation [7]. It is especially important when replacing the worn-out Central Heating and Power Plant equipment (in the course of upgrading thereof).…”

Abstract.One of the effective tools of solving engineering problems is the mathematical simulation of newly built and reconstructed industrial equipment. A necessity of solving identical problems fully belongs to generating equipment of thermal power plants too, which makes the use of methods of mathematic simulation quite a promising one in the course of designing power-generating units. The work presents the results of simulation and subsequent incorporation of the method of low-temperature vortex fossil solid-fuel combustion. Based on the developed algorithms and calculation program the assessment of environmental indicators of reconstructed boiler equipment has been carried out and compliance with environmental standards with respect to the level of emissions of gaseous pollutants into environment confirmed. The incorporation of the method being considered into power-generating production has made it possible to reduce emissions of gaseous nitrogen oxides during combustion of coals of different types by 30%.

Abstract.Work is devoted to the solution of problems of energy efficiency increase in low power boilers at combustion of solid fuel. The technological method of nitrogen oxides decomposition on a surface of carbon particles with education environmentally friendly carbonic acid and molecular nitrogen is considered during the work of a low-temperature swirl fire chamber. Based on the analysis of physical and chemical processes of a fuel chemically connected energy transition into thermal, using the diffusive and kinetic theory of burning modern approaches the technique, mathematical model and the settlement program for assessment of plant ecological indicators when using a new method are developed. Alternative calculations of furnace process are carried out, quantitative assessment of nitrogen oxides emissions level of the reconstructed boiler is executed. The results of modeling and experimental data have approved that the organization of swirl burning increases overall performance of a fire chamber and considerably reduces emissions of nitrogen oxides.
