environmental pollutions are in considerable attention in steel industries in iran, where mostly are located around isfahan. therefore, an investigation was done mainly on the industrial pollution and waste related to the isfahan steel complex. a plant was installed to collect the uncontrolled fumes, gases and particulates from blast furnace number ii during tapping. this plant collects about 2...
background: noise pollution is currently a major health risk factor for workers in industries. the aim of this study was to investigate noise pollution and implement a control intervention plan for blast furnace in a steel industry. methods: the measurement of sound pressure level (spl) along with frequency analysis was done with the sound-level-meter cell-450 . personal noise exposure was perf...
Industrial and experimental induction furnaces are used for melting various types of iron ingots, returned scraps and DRI sponge pellets to produce high purity cast - iron and steel heats. The lowest consumption of electrical energy determined for continuous feeding operation is 0.3 KWH/Kg for the production of cast - iron in a 1.5 - ton industrial furnace and 0.45 KWH/Kg for the production of ...
A commercially available computational fluid dynamics code has been used to simulate temperature and flow profiles in the upper, convective heat transfer region of a recovery boiler for different bullnose designs. The convective heat transfer region of the furnace was simulated by examining a zone that begins below the bullnose and ends at the economizer. Superheater tubes and a boiler bank wer...
Innovative Technology Summary Reports are designed to provide potential users with the information they need to quickly determine if a technology would apply to a particular environmental management problem. They are also designed for readers who may recommend that a technology be considered by prospective users. Each report describes a technology, system, or process that has been developed and...
A considerable amount of mill scale is generated from steelmaking plants annually. Although some industries use it as raw material however, since it contains iron in the form of FeO, Fe2O3, and Fe3O4, it can be considered as a valuable metallurgical raw material for iron and steelmaking industry as well. Thus, the aim of this study was to evaluate the possibility, efficiency, and consequences o...
In case of the currents asymmetry analysis for an induction furnace – symmetrizing circuit connected in a Steinmetz scheme, one of the most important aspects is represented by the negative asymmetry coefficient. This one can be determined knowing the positive sequence and the negative sequence components and the initial parameters R0 and X0 of the induction furnace. The testing algorithm follow...
