STRUCTURE OF FREE GAS OUTFLOWS FROM BLOWING NOZZLES OF THERMAL AGGREGATES

Popis výsledku v původním jazyce

Design and construction issues of blowing systems, lances and nozzles for high-temperature reactors is a hot issue, which addresses not only metallurgy but also other industrial sectors. In general, the problems of design and construction solutions are mainly oriented on issues of reducing the consumption of materials and energy, which ultimately affect the investment and operating costs of the aggregates. Among the most watched indicators can be included, for example, a reduction of the blowing media consumption while reducing the energy intensity of the technical production process and increasing the degree of its use. According to the nature of the distribution in individual determinating quantities, we can, when e.g. considering a metallurgical heat aggregate, determine the dynamic effect of a outlet flow on the working space (a bath), a change in the blown gas concentration and the best position of the lance with a view to increase its lifespan while reducing wear on the lining of the respective heat aggregate. Using the outlet flows from the lances we can analyse the parameters significantly affecting the design of the lance and nozzles intended for the given purpose. These are, for example, the interaction of outlet flows in multi-nozzle lances, the length of the supersonic flow core, the angle of outlet flows extension depending on the geometry of the nozzles, the effect of the nozzles shape on the outlet flow parameters and shaping of nozzles. Knowledge of the basic properties of the outlet flow field from the lances and nozzles helps designers and engineers to meet demanding requirements for the blowing systems. This paper presents the distribution and structure of free streams from lances including their selected characteristics.
