Estimating the industrial waste heat recovery potential based on CO_2 emissions in the European non-metallic Mineral Industry
Energy Efficiency, 2018Co-Authors: Laia Miro, Tobias Jager, Russell Mckenna, Luisa F. CabezaAbstract:Industrial waste heat (IWH) is a key strategy to improve energy efficiency and reduce CO_2 emissions in the Industry. But its potential for different countries remains unclear due to a non-existent or inconsistent data basis. The objective of this paper is to assess the IWH potential of the European non-metallic Mineral Industry, using databases which comprise CO_2 emissions of more than 400 industrial sites as well as country- and sector-specific parameters. This sector is selected because of its homogenous nature, meaning that most sites carry out similar or the same processes, which facilitates site-level modelling with subsector-level assumptions. The bottom-up approach is employed to derive the IWH potential for this Industry over the period 2007–2012. Average results in this period show an IWH potential per site of 0.33 PJ/a and a potential for the whole sector of 134 PJ/a. The countries with the largest IWH potentials are Germany, Italy, France and Spain with yearly average potentials of 23, 19, 17 and 16 PJ, respectively. The subsector with the most IWH potential is cement. Further work should focus on the improvement of methodologies to assess the IWH potential, in particular through a techno-economic assessment of links between IWH sources and potential sinks.

development of methodologies for the evaluation of wear resistant materials for the Mineral Industry
Wear, 1997Co-Authors: I R Sare, A G ConstantineAbstract:Abstract The paper reports the first part of a project aimed at developing methodologies for the evaluation of wear-resistant materials in mining and Mineral processing operations. A review of the literature revealed that almost no systematic studies have been made of wear phenonena in operating mining and Mineral processing plants. There have been a multitude of laboratory studies of abrasive wear phenomena which purport to have some relevance to field applications, but very few of these have produced meaningful information. There is little doubt that substantial cost benefits can be derived from a more systematic approach to wear problems. It was concluded that a detailed study needs to be undertaken to determine the total costs associated with wear, including not only the cost of the replacement items themselves, but also the cost of labour associated with replacing worn components and the cost of lost production. The realisation of the savings which can accrue through relatively modest outlays then become apparent. Techniques of experimental design and statistical analysis of data, combined with improved data collection and monitoring of field trials, have a key role to play in realising these savings.

the correlation of material characteristics and wear in a laboratory scale cone crusher
Wear, 2009Co-Authors: Paivi Kivikytoreponen, Sanna Alakleme, Jari Liimatainen, Jussi Hellman, Simo-pekka HannulaAbstract:Abstract Wear of materials is a widely recognised industrial problem. The direct costs of wear failures, such as wear part replacements, loss of productivity as well as indirect losses of energy, and the increased environmental burden, are real problems in everyday work and business. The Mineral Industry is particularly susceptible to wear part consumption resulting in high expenses. In this study, the performance of various steel-based wear resistant powder metallurgical metal matrix composites (MMCs) was studied for Mineral Industry applications. The matrix of the composites consisted of various tool steels, manganese steel and martensitic steel and the reinforcements used were tungsten carbides (WC), titanium carbides (TiC) or cemented carbides (WC/Co). Hot isostatic pressing (HIP) was used for compacting the materials. The performance of composite materials was studied in a laboratory scale cone crusher wear test. Correlations between the wear behaviour and microstructure parameters, such as volume fraction and the size of the hard particles and spacing between hard particles were investigated. It was found that the most important parameters in this wear environment were the total volume fraction of the hard phase and the type of the hard phase. A necessary feature of the matrix material is that it is also resistant to abrasion.
