Reduction of Open Hearth Furnace Particulate Emissions via a Parametric Study

the effect of consciousness raising (c-r) on the reduction of translational errors: a case study

در دوره های آموزش ترجمه استادان بیشتر سعی دارند دانشجویان را با انواع متون آشنا سازند، درحالی که کمتر به خطاهای مکرر آنان در متن ترجمه شده می پردازند. اهمیت تحقیق حاضر مبنی بر ارتکاب مکرر خطاهای ترجمانی حتی بعد از گذراندن دوره های تخصصی ترجمه از سوی دانشجویان است. هدف از آن تاکید بر خطاهای رایج میان دانشجویان مترجمی و کاهش این خطاها با افزایش آگاهی و هوشیاری دانشجویان از بروز آنها است.از آنجا ک...

Immersion Pyrometry and Open Hearth Furnace Productivity FASTER STEELMAKING AT RAVENSCRAIG

It is nowadays generally accepted that controlling the tapping temperature of steel by immersion pyrometry is an important means of improving steel quality. Broadly speaking, if the steel is too hot when tapped the ingots tend to crack, and if too cool they tend to suffer from “shell” on the surface and non-metallic inclusions beneath. From this point of view it is now simply a question of esta...

A KINETIC STUDY ON THE CARBOTHERMIC REDUCTION OF ZINC OXIDE FROM ELECTRIC ARC FURNACE DUST

In the present study, reduction of zinc oxide from the pellets made of steelmaking electric arc furnace dust has been investigated. Effects of such parameters as the type of carbon material (graphite, coke and charcoal) as well as time and temperature on the reduction reaction have been examined. The reduced (dimensionless) time method was applied to perform a kinetic analysis of the system. Ex...

Agricultural Particulate Matter Emissions: Preliminary Study

The Federal Reference Method (FRM) ambient PM10 sampler does not always measure the true PM10 concentration. There are inherent sampling errors associated with the PM10 samplers due to the interaction of particle size distribution (PSD) and sampler performance characteristics. These sampling errors, which are the relative differences between theoretical estimation of the sampler concentration a...
