Purpose. A research of a possibility of use of spatial electric field for creation of a thermal barrier to improve of turbulent gases motion in working space of the chamber furnace and increase in their density in an arrangement zone gardens from metal which heats up.
Methodology. By means of a complex of programs which allow to predict the movement of furnace gases taking into account turbulence of streams settlement researches of fields of their speeds in the camera are conducted.
Findings. The settlement research of whirl of products of combustion in the chamber furnace is executed. The picture of fields of speeds of gases in working volume is received and the analysis concerning efficiency of their use in a zone of an arrangement of metal products which heat up is carried out. It is established that the main part of warmth heats the top part of the furnace and only then falls down cameras where gases of insignificant density contact to metal, at the same time their bigger quantity just is removed through smoke windows, without having given warmth. The last leads to an excessive consumption of primary energy resource and reduction of power efficiency of the furnace in general. It is offered to create a thermal barrier by the direction of a quantity of the last perpendicular to that their part that are removed from the furnace. As the operating influence at this case serves noted ratio of volumes of gases. Results of modeling of the circulating movement of oven gases in the presence of a thermal barrier showed that their mass expense nearby of preparation grows, and it testifies to a possibility of achievement of the necessary temperature of metal at smaller expense of natural gas.
Originality. It is for the first time proved that it is expedient to apply a thermal barrier by creation of spatial electric field in the camera of the furnace between the burner and cages the metal.
Practical value. Introduction of the offered way of creation of a thermal barrier by means of spatial electric field can promote increase in energy efficiency of chamber furnaces.
