Compression Temperature

Compression of alfalfa into briquettes is an effective way to solve the problem of storage and transportation. In the process of compression, heat is generated and the temperature is raised in the material. In fact, the appropriate temperature can improve the quality of alfalfa briquettes and reduce the energy consumption of densification. In this study, the effect of assisted vibration on the compression temperature was tested. The results showed that when the vibration frequency was below 15 Hz, the temperature at the center and side in compressed alfalfa increased slowly with compression time. When the vibration frequency was above 20 Hz, it increased first and then decreased with the increase of time. Moreover, the maximum temperature value increased remarkably when the frequency was above 20 Hz. In the same vibration frequency and compression time, the center temperature in the compressed alfalfa was higher than the side temperature. The experimental results provide a reference for the determination of reasonable vibration parameters, and explanation of the effect of vibration on reducing energy consumption.

Through additional processing of the modern movement parameter recorders data of the DC electric locomotive 2ES6 the article first presents the results of the actual consumption of electricity for own needs and the proportion of these costs from the consumption of trains traction is determined, which in terms of operational depot is difficult to implement. The estimation of influencing factors on the energy consumption for own needs of 2ES6 series electric locomotives is made. As a result it was found that the internal energy consumption is influenced by such factors as rolling stock mass, axle load and environment temperature. Statistic models were made to normalize internal electricity consumption and their quality estimation was fulfilled. It is found that the remainders of the multiple regression equation, which take the above factors into account, obey the normal distribution law, indicating the adequacy of their further use to assess the energy efficiency of the 2ES6 series DC electric locomotives auxiliary equipment. The use of regression models will allow to identify electric locomotives with auxiliary equipment with low energy efficiency and to send them to unscheduled repairs in time to restore the required technical condition.

Recent literature on energy efficiency focuses on the issues of energy security and options for reducing energy consumption. Measuring energy efficiency properly and forecasting future needs is critical to the energy policies of any country, especially given the importance of sustainability in their economic development. The role innovation plays in improving energy efficiency is well researched. There is a gap in examining an opposite relationship. That is, where energy efficiency becomes a critical factor for fueling innovation. This impact can occur within a company, a region, a nation or on an international level. Here we show that regions could motivate business innovations through policies requiring energy efficiency. Based on observations from a number of regions of an emerging economy, we show that energy efficiency impacts innovation. As a side effect it can contribute to export increases, which in turn can improve regional attractiveness for investors. We believe that the spiral development of the relationship between energy efficiency and innovation used as a strategy could become sustainable.

The article proposes representation of crushing and grinding complex in form of a system with distributed parameters of the reducing function of the processed raw materials size in order to increase the energy efficiency of entire ore preparation process. Despite the fact that many different automated control systems for domestic and foreign production technological process are now used in the ore preparation processes, there is still a need to solve the problems of optimal control of such objects in order to both reduce energy costs and improve the quality of the final product. In terms of energy consumption, grinding processes are superior to crushing processes, so it is necessary to consider the crushing and grinding complex as a whole to increase the whole process energy efficiency. Since the processes of crushing, grinding and classification are purely random and at any time are characterized by transient probabilities, and the crushing and grinding complex occupies a large area and is geographically distributed in space, it should be considered as a system with distributed parameters of raw material size reduction, recyclable. Redistribution of loads between the individual components of this complex in accordance with the current characteristics of processed ore and the state of process equipment allows to reduce the load on the final stage - it is grinding, which in turn contributes to the overall reduction of energy consumption. The peculiarity of this approach is the need for the formation of spatial-temporal controls on basis of spatially distributed control of the object, the use of appropriate feedback signals and regulators with spatially distributed control effects.

Energy Indicators

The task of determining specific electricity consumption is complex, as it is necessary to take into account a large number of factors affecting the energy indicators that determine the level of these indicators. At the same time, the type and technical condition of the main and auxiliary process equipment in the process of melting, the nomenclature of metal, the volume of consumed components of the process and secondary energy carriers (compressed air, nitrogen, oxygen and other auxiliary components), etc. are taken into account. The error in taking these factors into account may lead to deviations from the actual values of the predicted power consumption, as well as energy indicators. The energy intensity of products and the level of energy consumption also depends on changes in the structure of energy consumption, the latter depending on the need for such process components as compressed air, oxygen, nitrogen, etc. The article considers the results of the analysis of energy indicators of enterprises of ferrous metallurgy, in particular, electrosmelting shop by types of output products on the basis of decomposition scheme. It is shown that the set task is solved by means of construction of dependences of normative energy characteristics on the volume of output products, and also the final decomposition tree is formed - the tree of tasks designed to achieve solutions of energy problems, including the main one - to obtain the value of specific energy consumption. In addition, the article presents the method of determining the share of participation of auxiliary components of the technological process for example of compressed air, nitrogen and oxygen. At calculations the account of the above-stated components gives the chance to define more precisely specific expense of the electric power.

Abstract The main task of the maintenance services in hard coal mines is to ensure continuous operation of the equipment (machines). The measurable effect of these actions should be the reduction of maintenance costs of equipment (machinery) and thus the reduction of production costs – coal mining. The paper presents an issue of failure rate of technical measures applied in the mining process. In order to ensure greater efficiency and productivity, it is necessary to find the causes of the most frequent failures in this process and effectively counteract them. As a result of these activities, the production availability of machines/equipment involved in the mining process will increase. This will to a large extent ensure failure-free and uninterrupted progress, increase productivity and improve the quality of manufactured products, as well as reduce the operating costs of equipment (machines), and thus reduce production and product costs. This effect should consist mainly in the control of rational, safe and effective use and operation of equipment (machines) in the exploitation process. An algorithm implemented in one of the hard coal mines was presented. The technical condition of underground mining equipment was observed by periodical measurements of vibration parameters at selected points on the machine – measurements were conducted with a vibration pen. The aim of this research is to improve the reliability of technological process of a mining plant through its failure-free operation. In order to achieve this objective, i.e. the efficiency of a mining company, it is necessary to reduce its costs. The action that leads to this aim is a proper assessment of the technical condition with regard to the equipment used in technological process.
