Aerosols emitted by antropogenic activity are in relationship to their emission source and exhibit distinguishable characteristics (size, metal concentration and density) that can often univocally identify the source. Nevertheless, different processes can characterize industrial plants that produce the same product. Due to this, dusts emitted by the same source can have different chemical compo...

Optimization of the power system plays a major role in power system planning. Unit Commitment and Economic Dispatching are the most important part of every plant-planning project. Unit Commitment is the problem that searches the economical way for power generation, when the power consumption and altered constraints of the power plants are considered. Recently, the attention of the environmental...

A better understanding of the discrepancies in multi-scale inventories could give an insight into their approaches and limitations as well as provide indications for further improvements; international, national, and plant-byplant data are primarily obtained to compile those inventories. In this study we develop a high-resolution inventory of Hg emissions at 0.05× 0.05 for Jiangsu, China, using...

One of the biggest promises of the Industrial Internet of Things is to leverage real-world data gathered through wireless sensor networks (WSN) to drive higher efficiencies and streamline business practices. The demands on WSNs are diverse, with sensors placed throughout buildings, city streets, industrial plants, tunnels and bridges, moving vehicles or in remote locations such as along pipelin...

Coal-fired power plants in the United States may have to reduce their mercury emissions by up to 90% by 2007 2009 due to proposed regulations that could affect up to 1,100 utility boilers. Air pollution control system components such as electrostatic precipitators, baghouses, NOx reduction catalysts, SO2 scrubbers, and their various configurations in utility applications significantly impact me...

The aim of this study is to analyze the reliability modeling indices and to study the mechanical system of a thermal power plant. The reliability of a system, equipment and a product is very important aspect of quality for its consistence performance over its expected life span. In fact, uninterrupted service and hazard free operation is an essential requirement of large complex systems like el...

Electricity generation in thermal power plants as the largest producer of electricity in Iran is associated with greenhouse gas emissions. In this paper, using the Malmquist-Luenberger method, green productivity, and efficiency changes are measured for 31 thermal power plants (including 12 steam power plants, 13 gas power plants, and six combined cycle power plants) during 2009-2016. The result...

Adding wind power to power systems will have beneficial impacts by reducing the emissions of electricity production and reducing the operational costs of the power system as less fuel is consumed in conventional power plants. Wind power will also have a capacity value to a power system. However, possible negative impacts will have to be assessed to make sure that they will only offset a small p...

Electric power generation system development is reviewed with special attention to plant efficiency. While higher efficiency is well understood to be economically beneficial because of fuel savings, its effect upon reduction of all plant emissions without installation of additional environmental equipment, is less well appreciated. As CO2 emission control is gaining increasing acceptance,effici...
