  • Detection of backlash phenomena appearing in a single Cement Kiln drive using the current and the electromagnetic torque signature
    IEEE Transactions on Industrial Electronics, 2013
    Co-Authors: Ioannis X. Bogiatzidis, Athanasions N. Safacas, Epaminondas D. Mitronikas
    Abstract:

    Fault diagnosis in electromechanical drives has been widely investigated over the last decades, and many diagnostic methods have been proposed based on the reported faults. Additionally to already published works which have dealt with gear faults inside low reduction ratio gearboxes, this paper aims to present a simple and effective method for the early diagnosis of evolving faults in a high reduction ratio gear transmission system used in Cement Kiln drives. The under study system basically consists of a three-phase induction motor mechanically connected to a gearbox. The output shaft of the gearbox drives a gear pinion which, in turn, rotates a girth gear rim surrounding the Cement Kiln. The identification of mechanical vibrations due to backlash phenomena appearing between the pinion gear and the girth gear rim of the Kiln is realized using the motor current signature analysis and processing the motor electromagnetic torque. The proposed diagnostic method is presented, analyzing the experimental results from an under-scale laboratory simulating system.

  • Investigation of backlash phenomena appearing in a twin AC Cement Kiln drive
    The XIX International Conference on Electrical Machines - ICEM 2010, 2010
    Co-Authors: Ioannis X. Bogiatzidis, Epaminondas D. Mitronikas, Athanasions N. Safacas
    Abstract:

    The existence of severe mechanical malfunctions and the appearance of mechanical vibrations due to these malfunctions is very critical especially for a high power electromechanical system working in an industrial environment. The reliable diagnosis and the early fixing of these malfunctions is authoritative concerning the demands of the industry. Such a critical electromechanical system for the Cement industry is the rotary Kiln. In this paper, the mechanical model of the rotary Kiln drive as well as the development of an appropriate laboratory simulating system in order to examine the effects of gear backlash phenomena appearing in a Cement Kiln rotated by a dual ac drive are presented.

  • test burn with pcb oil in a local Cement Kiln in sri lanka
    Chemosphere, 2010
    Co-Authors: Kare Helge Karstensen, Azeez M Mubarak, H N Gunadasa, Bandulasoma Wijagunasekara, N Ratnayake, Ajith De Alwis, Jayavilal Fernando
    Abstract:

    Abstract The production and use of polychlorinated biphenyls (PCBs) have ceased and most developed countries have disposed off their stocks long time ago. PCBs can however still be found in the environment and one important source is accumulated stocks in developing countries. Sound treatment of PCB is costly and most developing countries do not have dedicated hazardous waste incinerators or non-combustion technologies available for domestic disposal and can usually not afford export. High temperature Cement Kilns have been used to treat organic hazardous wastes in developed countries for decades and shown to constitute a sound option if well managed and controlled. In contrast to dedicated hazardous waste incinerators and other treatment techniques, Cement Kilns are already in place in virtually every country and may constitute a treatment option. The objective of this study was therefore to carry out the first test burn with PCB–oil in a developing country Cement Kiln and to assess its feasibility and destruction performance. The 3 d test burn demonstrated that the Sri Lankan Cement Kiln was able to destroy PCB in an irreversible and environmental sound manner without causing any new formation of PCDD/PCDF or HCB. The destruction and removal efficiency (DRE) was better than 99.9999% at the highest PCB feeding rate.
