To explore the mechanism for saving energy and reducing consumption in pelletizing process, the pelletizing process is decomposed correlatively into two parts: the material flow process and energy flow process. On this basis, it is studied that the physical and chemical changes and the flow mechanism in ferrite flow and carbon flow respectively, by analyzing the changes and conversion of the ferrite and carbon flow in pelletizing process, variation of material and energy flow has been summarized, using the law to guide the production, minimizing consumption of energy and maximizing resource utilization will be achieved. It provides another path to reduce energy consumption for steel plant.

Reduce Energy Consumption

One of the world’s topical issues is the necessity of energy consumption reduction in order to conserve less and less natural resources and protect the environment. The article deals with the need to develop the waste energy recovery solutions that reduce energy consumption among the industrial consumers. In order to identify the sources with recoverable potential and establish energy recovery solutions, thermography of the hot air and hot gas exhaust circuits from industrial technological facilities were performed, followed by monitoring the operation parameters and measuring the energy consumption. The energy consumption reduction is analyzed by comparative interpretations of the hourly consumption, before and after applying the optimal recovery solution. The analysis of the results revealed that the waste energy recovery during the technological facilities operation has, besides the economic benefit, also other positive energetic effects, technical and not at least ecological ones.

High Energy Consumption

In recent years, because of various reasons of auditing and calculating necessity for the rate of energy consumption and its savings have been as certain necessity. Among this, construction section has allocated more than one third of country’s energy consumption to itself that its value has been determined more than 6 billion dollars annually according to world prices. Now considering less attention to energy, almost all country’s buildings don’t have technical regulations for preventing wasting heat or cold energy and considering that swimming pools are building with high energy consumption and energy is used there mediating various factors, this research is sought to investigate the situation of energy consumption in pool of Imam Khomeini University Of Naval Forces. The most important energy consumer factors are sidewall thermal losses with surface evaporation of pool's water and air conditioning that finally mentioned performable solutions in pool will be investigated in terms of achieving energy consumption reduction. It is tried in this study to compare performed auditing with defined standards in nineteenth discussion of national regulations and by economic evaluating and the method of calculating return on capital of each action, the priority of doing performable actions in order to reduce energy consumption is determined and compared using existing software of modeling.

In continuous production industry, to develop energy-saving technology, an essential modeling method should be selected to reflect both production process and the energy consumption simultaneously. In this work, we propose a novel coupling model for production and energy consumption. In this production-energy-coupled model (PECM), four flows are included, the material flow, the energy flow, the information flow and the emission flow. The material flow is abstracted from traditional technological documents about process description; the energy flow represents the any kind of energy transformation and consumption of all possible energy sources used in current factories, the electrical power, coal, diesel, steam, water etc.; the information flow is the running status, pre-alarm, alarm information from the production devices, and the control information from the controller in a distributed computer system(DCS) in the production field or a remote control signal from a central dispatch & control center in a big enterprise; and the emission flow is defined as any kind of emission coming out from the production at both middle production units or the final units of a whole continuous production line. Finally some specific conclusions of the production-energy-coupling model (PECM) are drawn respectively.

AbstractThe paper analyses the role of control and monitoring of electro-energetic equipment in order to reduce operational costs, increase profits and reduce carbon emissions. The role of SCADA and EcoStruxure Power systems is presented and analysed taking into account the energy consumption and its savings. The paper presents practical and modern solutions to reduce energy consumption by up to 53%, mass by up to 47% and increase the life of the equipment by adjusting the electrical parameters. The Integrated Navigation System has allowed an automatic control and an efficient management. For ships, the implementation of an energy efficiency design index and new technologies was required for the GREEN SHIP project.

Current consumption of cloud computing has attracted more and more attention of scholars. The research on Hadoop as a cloud platform and its energy consumption has also received considerable attention from scholars. This paper presents a method to measure the energy consumption of jobs that run on Hadoop, and this method is used to measure the effectiveness of the implementation of periodic tasks on the platform of Hadoop. Combining with the current mainstream of energy estimate formula to conduct further analysis, this paper has reached a conclusion as how to reduce energy consumption of Hadoop by adjusting the split size or using appropriate size of workers (servers). Finally, experiments show the effectiveness of these methods as being energy-saving strategies and verify the feasibility of the methods for the measurement of periodic tasks at the same time.

Objectives: The Opportunistic Routing (OR) technique was explored in recent times and exhibits benefits over many existing protocols and can significantly reduce energy consumption during data communication with very limited compromise on performance. Methods : Using broadcasting nature of the wireless medium, OR practices to discourse two foremost issues of variable link quality and unpredictable node agility in constrained WSNs. OR has a potential to reduce delay in order to increase the consistency of data delivery in network. Results : Various OR based routing protocols have shown varying performances. In this paper, a detailed conceptual and experimental analysis is carried out on different protocols that uses OR technique for providing more clear and definitive view on performance parameters like Message Success Rate, Packet Delivery Ratio and Energy Consumption.
