The fabrication and properties of carbon nanofibers are interesting because of the fiber’s expected conductivity properties. If we can successfully control the fabrication and manipulation of carbon nanofibers we should be able to build nanoscale electronics. In this attempt, we have been able to successfully control some of the properties for the fabrication of nanofibers. Carbon nanofibers we...

An integrated system of a microreformer and a carrier allowing for syngas generation from liquefied petroleum gas (LPG) for micro-SOFC application is discussed. The microreformer with an overall size of 12.7 mm × 12.7 mm × 1.9 mm is fabricated with micro-electro-mechanical system (MEMS) technologies. As a catalyst, a special foam-like material made from ceria-zirconia nanoparticles doped with r...

The evolution from natural gas usage to new technologies, such as the use of hydrogen fuel or electricity‐based heating, strongly influences oxidation stainless steel surface in reheating furnace. Thermogravimetric tests using different simulated combustion and induction conditions were performed for austenitic AISI 301 304, ferritic 444 grades. Simulated furnace atmospheres methods based on me...

Since Priestley utilized the radiant energy of the sun with his burning glass in his famous experiment of 1774, the method has fallen into disuse and the chemist has accepted the water-bath, the hot-air oven, and the furnace as the standard tools for evaporation, drying, and combustion. The boiling water-bath is used for evaporating solutions or drying solids which decompose at temperatures sli...

Induction Heating Furnaces are used extensively in industry. The basic principle is that induced eddy currents are used to heat a ferromagnetic material as it passes through a series of coils. Because of the importance of such systems, there has been on-going interest in their design and operation. Past work includes model development from physical principles and optimal design of operational p...

Silicon is produced in submerged arc furnaces which are heated by electric currents passing through the furnace. It important to understand distribution of heating within furnace order accurately model silicon production process, yet many existing studies neglect aspects this current flow. In present paper, we formulate a that couples electrical thermal, material flow and chemical processes We ...

An important aspect of non-ferrous metal production is the separation process known as smelting, in which the concentrated ore is melted and separated into two components of different densities: the slag and the matte. The smelting process is carried out through high-power heating in electric arc furnaces. In order to maintain a constant desired matte production rate and constant matte and slag...
