In reactor furnace, due to high temperature and high pressure, data can be measured only near the furnace wall. In this paper, the way to estimate temperature distribution in a reactor furnace using measured data near the furnace walls and to control temperature distribution to the desired temperature distribution was studied. In the estimation, SQP method is employed using measured data near t...

In an effort to develop breakthrough technologies that enable drastic reduction in CO2 emissions from steel industry (ULCOS project), the reduction of iron ore by pure hydrogen in a direct reduction shaft furnace was investigated. After experimental and modelling studies, a 2D, axisymmetrical steady-state model called REDUCTOR was developed to simulate a counter-current moving bed reactor in wh...

The article presents a mathematical model of the heat transfer process when heating metal in furnace, which describes thermophysical processes that occur using industrial technology for castings. A simplified convective and radiant is based on conventional differential equations, allows to calculate time metal. It you evaluate furnace find its optimal parameters. widely used can be applied stud...

Industrial landfills resulting from operations of various industries, particularly power generation, create specific habitat conditions for flora. Among the waste which may be used for recultivation of dumping heaps there is sewage sludge, which contains a considerable amount of nutrients crucial for plants. This investigation aimed at identification of the effect of sewage sludge and furnace a...

Abstract. This contribution is based on a joint research project developed by the University of Ferrara, Department Architecture (Italy) and Escola Politecnica USP São Paulo (Brazil) which it was possible to scan interior exterior surfaces ancient blast furnaces João do Ipanema, an extraordinary example industry cast iron production XIX century.The aimed at investigating evolution furnace techn...

The use of residual gases from steel production processes as fuel for treatment furnaces has attracted great interest a method reducing fossil consumption and the footprint. However, these often have low calorific value, direct substitution can lead to temperatures or combustion instability issues. CFD simulations help producers forecast results before real testing implementation. In this study...
