Abstract
MODELING EFFICIENCY OF PULVERIZED COAL IN BLAST SWIMMERS Dovgaluk B.P., Voloshyn R.V. Abstract Modern production domain focused on pulverized coal, which is used in more than 30 countries. Using requires monitoring of its effectiveness, oxidation of elements in iron lance and loss of heat from the cooling water. The authors modeled on the efficiency of and modeling efficiency of pulverized coal in the blast swimmers taking into account fluctuations in iron oxidation elements lance and loss of heat from the cooling water. To determine the feasibility of controlling heat loss modeled their significance and possible impact on the state of the thermal melt. Calculated heat flow for temperature drop on 1C. Productivity ovens per hour was measured volume of furnaces and utilization of useful volume of the furnace. If the water temperature drop t take an average of 6-8 C, and for lance 12-14 C, the effect of heat loss to the thermal state of melting too significant and will cause a significant change in the parameters of quality and performance cast iron stove. Thus, automated control heat loss of cooling water needed, especially during the use. References [1] V.V. Klimchuk., N.V. Kosolap., I. A.
