steel industry is one of the most consumption of energy in the world, which is related to melting furnace which result environmental pollution. we calculate the energy consumption and capital cost of dust collectors of venturi scrubber (vs) and electrostatic precipitator (esp) which are connected to melting furnace in respect to industrial ecology for selection of appropriate dust collection sy...

The MIT Microengine Project is an ongoing effort to build a MEMS based gas turbine engine and turbogenerator. This thesis covers the development and testing of the packaging needed for the microengine and related devices. The packaging of the microengine includes the fluidic, electrical, and sensor connections that interface the engine with the supplies and instruments necessary for operation. ...

Ferrochrome is the major chromium source for stainless steel production, and submerged-arc furnaces (SAF) are most commonly utilised to smelt chromite ores into ferrochrome by using suitable carbonaceous reductants such as coke. Because of the complexity of feed structure and electrical-thermal-chemical interactions, there exist large gradients and wide distributions of temperature, mineralogy ...

In order to discuss the atomization process of an analyte element occurring in a graphite furnace for atomic absorption spectrometry, we measured variations in the characteristic temperature with the progress of an atomization stage, by using a two-line method under the assumption of a Boltzmann distribution. For this purpose, iron was chosen as the analyte element. Also, the atomic absorption ...

Airborne particulate matter in the silicon carbide (SiC) industry is a known health hazard. The aims of this study were to elucidate whether the particulate matter generated inside the Acheson furnace during active operation is representative of the overall particulate matter in the furnace hall, and whether the Acheson furnaces are the main sources of ultrafine particles (UFP) in primary SiC p...

In this paper, by using the data of steel melting plant which contains major non-linear load i.e., induction furnace, we modeled such a system, which contains three 12-tons induction furnace in PSCAD software and simulated for three different operating conditions & studied harmonic pattern.
