Industrial rotating kiln simulation
… oil shales. As part of this process, a rotating kiln is used to pyrolyse the organic component of the oil shales. The configuration and application of this rotating kiln is unique and hence previous rotating kiln models cannot be used to predict the solid behaviour in the current processor. It is …

A time-based computer controlled dry kiln system
A computer controlled dry kiln system, designed and assembled at Virginia Tech, was used in a comparison study of end check damage and acoustic emission count rate for red oak wood samples using two variations of a drying schedule based upon a standard 4/4 red oak drying schedule (T4D2). Time was …

Direct reduction of iron ore in a rotary kiln
… iron ore was reduced successfully in a rotary kiln with a gaseous reactant which was prepared by reforming butane within the kiln, using the beneficial effect of iron/iron oxide as an autocatalyst. The optimum ratio of the gaseous reactants, H2/CO2/C4H10, was used to prevent undesirable soot …

Moisture Gradient Measurement During Kiln Drying of Red Oak
… effect on transverse moisture movement during kiln drying was examined through measuring moisture gradients in the tangential and radial directions of wood. The results showed that moisture moved slightly faster in the radial direction than in the tangential direction during kiln drying and the …

Kraft lignin as a fuel for the rotary lime kiln
… a solid fuel which could be burned in the lime kiln. In order to test the suitability of the precipitated lignin as an alternate fuel, a 0.4 m ID by 5.5 m pilot rotary kiln was modified with a computer controlled screw feed system and a water-cooled lance in order to burn dry powdered lignin, …

Combustion of lignin-oil-water mixtures in a rotary kiln
… lignin would be used as a fuel in the lime kiln, replacing the external fuel, such as natural gas or fuel oil, presently used. In this work lignin-oil-water mixtures were investigated as a fuel. The rheology of the lignin-oil-water mixtures was studied; and a pilot scale preparation facility …

Modular making in kiln cast glass: repetition, efficiency, and the unique
… studio casting processes, focussing primarily on kiln cast glass. In their traditional conception, modular systems developed to improve efficiency – allowing limited parts to be combined and recombined in different ways to introduce a degree of variety. However, such systems require …

The monitoring and control of specialist ceramic kiln atmospheres and emissions.
… conditions with the use of potentially hazardous kiln atmospheres and specialist kiln designs for their successful execution. The technique of reduction lustre is an ancient, highly decorative technique in which pigments or glazes containing reducible metal oxides such as copper, silver and …

Simulation of Combustion and Thermal-flow Inside a Petroleum Coke Rotary Calcining Kiln
… the calcining process inside the long slender kiln. Simplified models are employed to simulate the moving petocke bed with a uniform distribution of moisture evaporation, devolatilization, and coke fines entrainment rate with a conjugate radiation-convection-conduction calculation. The results …

Rotary kiln transport phenomena: a study of the bed motion and heat transfer
Thermal processing of materials in rotary kilns involves heat transfer from the freeboard to the boundary surfaces of bed material and the distribution of this thermal energy within the granular bed. Although the former has been reasonably well characterized, the latter has not, mainly because of …

Rotary kiln incineration of hazardous wastes: pilot-scale studies at Louisiana State University
… wastes are conducted in the pilot-scale rotary kiln incinerator (RKI) at Louisiana State University (LSU) in Baton Rouge, Louisiana. The purpose of the research is to investigate methods of treating and destroying hazardous wastes in a cost-effective and environmentally sound way. The objective …

Improvement of kiln design and combustion/carbonization timing to produce charcoal from agricultural waste in Developing countries
… high temperature in an air-tight metal barrel kiln to produce char. The char produced from Haiti's main agricultural waste product, bagasse, must be powderized, mixed with a binder, compressed into briquettes, and finally baked. The purpose of the thesis was to improve on key areas of the …

Nineteenth century stoneware manufacturing at Pottersville, South Carolina: the discovery of a dragon kiln and the reinterpretation of a southern pottery tradition
… of this research project was the Pottersville kiln site (38ED011) located in Edgefield, South Carolina (circa 1810-1850 C.E.). That production center was founded by Abner Landrum and is renowned as a first place of the manufacture of alkaline-glazed stoneware vessels in the Americas. The …
