Title of the articleNumerical investigations of the perfection of gas combustion in the furnaces of domestic heat generators
Abstract.Problem statement. The purpose of the study is to improve the combustion devices from the standpoint of torch constraint and the completeness of the process of oxidizing the combustible components of the air-fuel mixture is especially important for household generators, since the desire for compactness of the furnace significantly affects the size of the device. Results. In the course of carrying out numerical studies, the combustion characteristics are determined depending on the design features of the furnaces of the Bosch boiler Unimat UT-L18, the gas heating convector FEG Beata 2 and the Viessmann condensing boiler Vitodens 100-W. The equipment is selected based on the degree of tightness of the torch in the furnace. The degree of constraint here is understood as the ratio of the geometric volumes of the torch and the firebox, taking into account the design features of their forms and mutual arrangement. The possibility of a quantitative analysis of the degree of perfection of the design parameters of the furnaces of gas-using devices in order to find a reserve of energy saving and economical use of fuel is provided. Conclusions. The significance of the results obtained for the construction industry consists in the possibility of improving energy-saving technologies for the design and construction of heat supply systems for buildings of various purposes. Their use makes it possible to design furnace devices that exclude the disconnection of elementary stages of methane oxidation and the death of active centers of fuel combustion processes on the walls of screen surfaces.
