    Applications of microwave pretreatment in coal [Kömürde mi·krodalga i·le öni·şlem uygulamalari]
    (2007) Toraman Ö.Y.; Depçi T.
    Microwaves are a form of electromagnetic energy associated with electric and magnetic fields. Microwave energy has a great potential in coal industry in comminution, desulphurisation and drying processes. This paper presents a review of the advances in the microwave treatment of coal and many different applications are considered, including the heating rate investigations, grindability, desulphurisation and dewatering studies.

    Technological and ecological developments in the modern thermal rower plants [Modern termik santrallerde teknolojik ve ekolojik geli§meler]
    (Chamber of Mining Engineers of Turkey, 2013) Delibalta M.S.; Toraman Ö.Y.
    The rapid increase in worldwide energy demands and its environmental impacts directs countries for more strategic energy policies. In terms of environmental impact of energy and security of supply, there is no source which has zero risk. In 21 century, coal is regarded as the world's most important and reliable source of energy. Our country is facing a serious energy supply security. In this process, the most rational thing can be done is to use the limited resources efficiently, economic and ecologically. Today, in the level achieved technologically, the capacity of conventional thermal power plants must be definitely improved and required rehabilitation. Carbon capture and storage (CCS) techniques have been developed the concept of traditional availability of fossil resources. Furthermore, to adopt the terms of mitigation of carbon dioxide (CO2), the use of different areas of CO2 such as chemical, biological and biotechnological products, has been investigated. It can be seen in western European countries the best practice examples of this. In this study, in order to contribute our country's energy policies and strategies and acquire new technologies to the sector, technological and ecological developments in modern thermal power plants were examined.

    Ultra fine wet grinding in stirred ball mill: Part I. Grinding mechanism and process parameters [Kariştirmali bilyali degirmende çok ince yaş ögütme: Bölüm i. ögütme mekanizmasi ve proses parametreleri]
    (Union of Chambers of Engineers and Architects of Turkey, 2015) Toraman Ö.Y.
    Stirred ball mills are better suited than other mills for the production of ultra fine and submicron-size particles. Ultra fine and submicron grinding by means of stirred ball mill is a highly energy-intensive process, and it is necessary to optimize energy usage by determining the optimum operational parameters for the mill. The aim of this review is to present some of the previous work with respect to the grinding mechanism and process parameters in ultra fine wet grinding with stirred ball milling.

    Ultra fine wet grinding in stirred ball mill: Part II. Slurry rheology and stability [Kariştirmali bilyali degirmende çok ince yaş ögütme: Bölüm II. Palp reolojisi ve duraylilik]
    (Union of Chambers of Engineers and Architects of Turkey, 2015) Toraman Ö.Y.
    With an increasing demand for super fine powders for industries, wet ultra fine grinding has been increasingly used in various fields, such as minerals, ceramic materials, pigments, pharmaceutics and paper-making. Most of the mills used in ultra fine grinding are stirred ball mills. The basic grinding mechanisms in stirred mills are dependent on shear, compressional and torsional stresses. The effective motion of the mixture (particles and grinding media) is much related to the flow field in the grinding chamber. It has been known that slurry rheology affects the wet milling of materials. Therefore, the effect of the slurry rheology to the milling becomes of particular importance. The aim of this review is to present main principles and some previous work with respect to the slurry rheology and stability in ultra fine wet grinding with stirred ball milling.
