The goal of the latest strategy in glass companies is to decrease the cost of production while maintaining or increasing the glass quality. There are several perspective ways leading to this goal: Optimization of the heating system, Modification of the furnace design, or Installing the new advanced control system. Optimization of the heating system can be achieved by installing modern burner sy...

In the paper, course of post-reaction gas afterburning generated during metallurgical process where reduction metal and semi-metal oxides is performed with use carbon presented. Process waste gases can be an alternative source energy to used in same or converted another. The participation chemical enthalpy total stream 93 %, rest physical enthalpy. study, particular attention was paid proper mi...

Abstract A tapping process model of the steel from basic oxygen furnace (BOF) addressing reactions in ladle is proposed. In model, effective equilibrium reaction zone (EERZ) method applied to describe steel/slag interfacial reaction. The bulk (steel/inclusion/lining wear) and slag (liquid slag/slag additions/lining are considered. thermodynamic library—ChemApp used perform calculation. includes...

Abstract Flash smelting and flash converting are mature technologies in copper nickel sulfide smelting. The sensitivity of operation concerning the furnace design is evident. It obvious that when two unit operations carried out separate spaces same furnace, skills related to maintenance suspension oxidation fine minerals, fluxing, fluid as well heat flows overall energy balance required. Despit...

This paper concerns the mathematical modelling and numerical solution of thermoelectrical phenomena taking place in an axisymmetric induction heating furnace. We formulate the problem in a two-dimensional domain and propose a finite element method and an iterative algorithm for its numerical solution. We also provide a family of one-dimensional analytical solutions which are used to test the tw...

Power quality is becoming a more concern of today’s power system engineer due to rapid growth of non-linear loads in distribution network. Electrical Arc Furnace (EAF) is one of the responsible causes for deteriorating power quality in the distribution network. Hence electric arc furnace model is needed to study and to analyze the power quality in the distribution network. This paper presents a...

The design of system for operative planning of blast furnace production process in VSŽ inc. Kosice A system for operative planning of blast furnace production process is described in the paper. The suggested system is based on the use of a new hierarchy of operative plans, consisting of one-month plan, (7+3) days plan, and 24-hour plan. The system allows smoothing of production process at the b...

The reaction behaviour of partially reduced iron (PRI) was studied to understand the effect PRI utilisation in blast furnace process. For quantitative analysis, under typical operating conditions a measured using thermogravimetric method along with reduction hematite and sinter. Experimental results indicated that reoxidation upper shaft retarded indirect rate lower shaft. constants derived fro...
