Energy audit methodology for belt conveyorsMarx, Dirk Johannes, Lewies 11 April 2007 (has links)
The electricity cost is one of the largest components of operating costs on a belt conveyor system. This dissertation introduces a unique Conveyor Electricity Cost Efficiency Audit Methodology (CECEAM). In the CECEAM the conveyor system is evaluated from a high to detail level in order to identify opportunities to improve electricity costs. The CECEAM includes methodologies and tools developed to analyze not only the conveyor belt alone, but also the materials handling system as a whole. The outline of the dissertation is structured as follows: Chapter 1 includes the background and problem identification by means of a literature study. The main objective, as well as specific objectives, is defined in this chapter. In chapter 2, the CECEAM is introduced and an overview of the total methodology is discussed. The data acquisition part of the CECEAM; documentation, personnel, walk, technical audit as well as the conveyor database is discussed in chapter 3. Chapter 4 concentrates on the Conveyor Energy Conversion Model (CECM) and the verification thereof. The Integrated Conveyor Energy Model (ICEM) methodology is introduced (in chapter 5) and the economic evaluation concepts and energy management basics needed in the CECEAM are covered. Chapter 6 covers a CECEAM case study where the practical application of the CECEAM is illustrated with ICEM simulations, opportunity identification and recommendations. The conclusion and recommendations for further studies is proposed in chapter 7. / Dissertation (MSc (Electrical Engineering))--University of Pretoria, 2007. / Electrical, Electronic and Computer Engineering / unrestricted

CFD simulace proudění páry v neregulovaném odběru parní turbíny / CFD simulation flow of steam in the unregulated extraction of steam turbineFilip, Patrik January 2017 (has links)
Diploma thesis named CFD simulation of the steam flow in the unregulated extraction of the steam turbine is about an analysis of the balance piston impact on the area of the steam turbine, where the extraction is located. First part describes basic knowledge of the steam turbine in general. At the end of this chapter, there is a description of the solved steam turbine. Next chapter is about introduction to the CFD. Practical part deals with a construction of 3D models, meshing and setting of the boundary conditions in the program ANSYS CFX. The main part of this thesis summarizes the results of the CFD simulation and stipulates the temperature range on the extraction pipe. In conclusion, there is a recommendation how to determine design temperature of the extraction pipe influenced by the balance piston.

Transnational organizing: a case study of contract workers in the Colombian mining industryRoyle, Tony, Cotton, E. January 2014 (has links)
No / This article examines recent organising successes in the Carbones del Cerrejón coal mine, reversing the organisational crisis of the Colombian mining union, Sintracarbon. Using Wever's concept of ‘field-enlarging strategies’, we argue that these events were facilitated by the dissemination of organising experiences between affiliates of a Global Union Federation, International Federation of Chemical, Energy, Mine and General Workers' Unions (ICEM), which recently merged to form IndustriALL. Additionally, we argue that this articulation between international and national unions, based on the principle of subsidiarity, was facilitated through sustained ICEM educational project activity, providing multiple entry points for Sintracarbon to operationalise its strategy and re-establish bargaining with multinational employers.
