Abstract The Flash Smelting Furnace (FSF) is one of the most common reactors for primary smelting copper concentrates. Its smooth operation depends on availability and performance downstream Waste Heat Boiler (WHB). WHB especially sensitive to problems with its flue dust handling, such as formation accretions, which can lead downtime equipment failures. Due limited accessibility harsh condition...

Mercury displays a different reactivity and behaviour depending on its speciation. Determination of the mercury species present in combustion flue gases is important for proposing effective control technologies. The Ontario Hydro (OH) method is accepted as the only wet-chemical method suitable for measuring total and speciated mercury in flue gases. However, the continuous development of combus...

Abstract Within the steelmaking industry, a large amount of zinc-bearing waste is produced which cannot be effectively treated through integrated steel mills. Concurrently, zinc smelters generate residues containing significant amounts iron and are stored or landfilled. The concentration inhibits its recycling to blast furnace but insufficient sent directly producers. Consequently, means up-con...

CO2 emissions from combustion flue gases have turned into a major factor in global warming. Post-combustion carbon capture (PCC) from industrial utility flue gases by reactive absorption can substantially reduce the emissions of the greenhouse gas CO2. To test a new solvent (AIT600) for this purpose, a small pilot plant was used. This paper presents the results of studies ...

Distribution of Heavy Metal from Flue Gas in Algal Bioreactor

Tobacco (Nicotiana tabacum L.), particularly flue-cured tobacco, is one of the most economically important nonfood crops and is also an important model system in plant biotechnology. Despite its importance, only limited molecular marker resources are available for genome analysis, genetic mapping, and breeding. Simple sequence repeats (SSR) are one of the most widely-used molecular markers, hav...

Flue gas conditioning (FGC) systems offer an effective option for control of Particulate Matter (PM) emissions and enhances the performance of the Electrostatic Precipitators (EPs) when using coal of different properties. The increasing environmental awareness and the mandate of the Environmental Protection Agencies (EPA) in various countries to thermal power stations using coal-fired boilers f...

Superheater is for generating superheated steam from the saturated steam from the evaporator outlet. In the case of pulverized coal fired boiler, a relatively small amount of ash causes problems with ash fouling on the heating surfaces, including the superheaters. In the convection pass of the boiler, the flue gas temperature is lower and ash deposits can be loose or sintered. Ash fouling not o...
