Abstract:
An experimental investigation of rotary kiln heat transfer processes was carried out and a unified heat transfer model developed to describe the individual processes and their interaction. A 0.406 m ID by 5.5m refractory lined pilot kiln firing natural gas was utilized for a series of 23 heat transfer trials. Limestone, petroleum coke and two Ottawa sands were heated using a wide range of firing rates while rotation rate, kiln inclination, kiln loading and bed depth were held nearly constant. The bed material was in the rolling mode for all trials. Measurements were made to obtain the net hea

The elutriation of fine materials from the solids bed in rotary kilns was studied in a laboratory scale steel cylinder of 0.2m in diameter and 2.4m in length. The cylinder was charged with a batch of fine alumina particles having a mean size of 64jum and the average elutriation rate measured at different air flow rates, rotational speeds and percentage of solids fill. All measurements were done at room temperature. To show the effect of fines concentration and segregation in the solids bed, a binary mixture of fine alumina and coarse Ottawa sand was used.

The Fuels and Energy Research Group at the university of Surrey (FERGUS) have been investigating the heat transfer and energy utilisation within rotary cement kilns since the early 1970's. One such project has been the study of chain systems in cement kilns. The work presented in this thesis is an investigation of a chain system for dry process cement kilns. A review of the literature has highlighted that there is a general paucity of experimental work on cement kilns, and in particular, very little on the role of chain systems. This lack of applicable results is due to the fact that experimen

Rotary kilns are important in a variety of different manufacturing areas for e.g. calcination and sintering of materials. In fact, two of the most produced materials in the world, cement and iron, are likely to start their journey in a rotary kiln.A rotary kiln is a large cylinder-formed furnace which rotates about its axis and where certain chemical and physical reactions take place by the influence of heat. The slope and the rotation make the material inside to move through the kiln from feed to discharge end. Due to high process temperatures the casing of the kiln is insulated by a refracto

Abstract:
Biochar has been heralded as a promising technology for climate change mitigation that can also benefit soils. Biochar is a carbonaceous solid produced by pyrolysis of biomass – the thermal decomposition of plant and plant-derived matter in the absence of oxygen. When added to soils, biochar has the potential to increase crop yields and suppress soil emissions of greenhouse gases, whilst sequestering carbon in a stable form. In addition to biochar, biomass pyrolysis produces liquids and gases that can serve as biofuels. Biochar production systems that generate excess heat or power are particul

Calcined coke is the best material for making carbon anodes for smelting of alumina to aluminum. Calcining is an energy intensive industry and a significant amount of heat is wasted in the calcining process. Efficiently managing this energy resource is tied to the profit margin and survivability of a calcining plant. 3-D computational models are developed using FLUENT to simulate 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 entrai

Abstract:
L’esigenza di aumentare l’efficienza e la redditività degli impianti industriali e l’esigenza di rispettare rigorose norme sull’impatto ambientale, accanto alla necessità di un adeguamento a precise norme di produzione, richiedono un livello crescente di automazione. L’attività di ricerca svolta ha riguardato lo sviluppo e l’implementazione di soluzioni per l’identificazione e la modellazione di sistemi dinamici. Questi sistemi sono stati poi utilizzati al fine di progettare, implementare e testare varie politiche di controllo finalizzate al risparmio energetico. Inizialmente sono state valuta

A finalidade deste trabalho é estudar a redução carbotérmica de minério hematítico com misturas e pelotas autorredutoras em um forno rotativo experimental. Trabalhou-se com duas temperaturas, a 1673 e 1773 K (1400 a 1500 °C), em fluxo de argônio de 1Nl/min, em um forno rotativo experimental aquecido por resistências, com uma rotação fixa de 5 rpm. Foram realizadas diversas experiências, alterando variáveis como a temperatura, composição e quantidade da escória, tipo de redutor, e tipo de conformação. Foi estudado o tempo de residência das pelotas e misturas autorredutoras dentro do forno e sua

En raison de l'épuisement des combustibles fossiles et en raison de son coût croissant, les déchets ont été utilisés comme combustibles alternatifs dans les fours rotatifs à ciment pendant plusieurs années. Afin de répondre aux exigences de protection de l'environnement et de qualité du produit final, il est nécessaire de comprendre et de quantifier les différents processus intervenant dans le four. Dans le cadre de cette thèse, nous nous sommes intéressés à la substitution partielle des déchets (pneus usés et Refuse Derived Fuel « RDF ») et biomasse (résidus d’agriculture) dans les fours tour

Дисертація присвячена підвищенню екологічної безпеки цементного виробництва при використанні альтернативного палива на основі горючих відходів (відходи оброблення макулатури, відходи тари пластикової дрібної використаної, тирса деревинна і зношені автомобільні шини) для заміщення частки кам’яного вугілля у процесі випалювання портландцементного клінкеру в обертових випалювальних печах. У результаті проведених досліджень розроблено тверде альтернативне паливо на основі відходів оброблення макулатури, відходів тари пластикової дрібної використаної і тирси деревинної для цементної промисловості.

The content is divided into two parts : experiment and dimensional analysis. As to experiment, we measure the sesame thermal conductivity and find that when the temperature is between 20℃ and 70℃ and the moisture rate is 14.3%, the thermal conductivity: where K: Thermal Conductivity, W/m-℃
