A mathematical model of a continuous reheating furnace has been developed to identify the design and operating parameters that significantly affect furnace performance. In this study, the furnace is modeled 3 dimensionally and theMonte Carlomethod is used to find the overall absorption factor. The overall absorption factor is then used to calculate the energy balance for furnace walls, the gas,...

The objective of this study was to develop an integrated simulation model of an automatic blast furnace in a full-scale steelmaking factory. The integrated simulation model introduces a set of optimizing alternatives through sensitivity analysis. The simulation model is built by considering all major and detailed operations and interacting systems of the blast furnace workshop. The workshop is ...

background & objectives: tubular adenomas are rare benign epithelial tumours of breast affecting predominantly females of child bearing age group. till now, very small number of cases have been reported in the literature. present study was carried out to evaluate the clinico-pathological features of tubular adenoma cases diagnosed during three years study period along with discussion of pos...

The walking beam furnace is one of the most prominent process plants often met in an alloy steel production factory and characterised by high non-linearity, strong coupling, time delay, large time-constant and time variation in its parameter set and structure. From another viewpoint, the walking beam furnace is a distributed-parameter process in which the distribution of temperature is not unif...

Many solid materials contain nanoparticles to enhance their functionalities. The question of whether they may release at different moments life cycle is raised. Lifecycle includes waste management. There therefore a need determine the fate when are incorporated in incinerated. present study aims shedding light on these issues. In this context, three real-life wastes selected for specific compos...

Two atomic absorption techniques, acid digestion followed by conventional flame analysis and directanalysisof solidsamples with the graphite furnace, were compared forthe determination of copper in fingernails. Nail samples, from 11 persons, containing between 5 and 50 1zg/gof copper, were analyzed by both methods. There was good correlationbetween resultsofthe two.The furnace requires less sam...

Abstract: Properly understanding heat flux characteristics is a crucial prerequisite to efficiently applying a regenerative burner in an aluminum reheating furnace. A series of experiments was conducted in this study in order to establish a database of the best available burners according to furnace temperature, excess air ratio, and flame combustion mode as they affect heat flux characteristic...

Co-pyrolysis of Shenmu coal (SM) and cotton stalk (CS) at different blend ratios were carried out in a tubular furnace. The pyrolysis temperature was up to 600 °C at 5 °C/min and kept for 15 min. The results indicated that there was an interactive effect between SM and CS, which increased the tar yield. Moreover, the content of light components in co-pyrolysis tar from all CS/SM blend ratios wa...

background: radioactive yttrium glass microspheres are used for liver cancer treatment. these yttrium aluminum silicate microspheres are synthesized from yttrium, aluminum and silicone oxides by melting. there are two known processes used to transform irregular shaped glass particles into microspheres, these ‘spheroidization by flame’ and ‘spheroidization by gravitational fall in a tubular furn...
