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...
متن کاملIzapa: Cultural Hearth of the Olmecs?
Located near the edge of the Pacific coastal plain in the far southeastern corner of Chiapas, Mexico, is the large pre-Columbian ceremonial center known as Izapa. Situated on the terrace of a small stream tributary to the Rio Suchiate, the border river between Mexico and Guatemala, the site consists of more than 130 mounds sprawled over several hectares of lush tropical lowland at the base of t...
متن کاملInput Variable Selection in Modelling of Desulphurization Efficiency
Several methods are applied to find the input variables with predictive power to the degree of desulphurization modelling. The methods are applied on the data from a desulphurization plant processing flue gases coming from a coal-fired power plant. In non-linear and complex industrial processes, the nature of the relationships between the variables may be vague and a functional model based on a...
متن کاملThe capture of oxidized mercury from simulated desulphurization aqueous solutions.
Elemental mercury in flue gases from coal combustion is difficult to control. However, oxidized mercury species are soluble in water and can be removed with a high degree of efficiency in wet flue gas desulphurization (WFGD) systems operating in coal combustion plants, provided that no re-emissions occur. In this article the mechanisms affecting the re-emission of oxidized mercury species in WF...
متن کاملDynamics of wet flue gas desulphurization in spray absorber
A concise one dimensional thermal-hydraulic two-fluid model is presented for the numerical prediction of sulphur dioxide absorption from the flue gas onto drops of the water-limestone slurry in the vertical spray tower absorber. The model is based on mass, momentum and energy balance equations for each phase separately, i.e. downward falling droplets of water-limestone slurry and upward flowing...
