China is now facing great challenges resulting from climate change and air pollution, driven by the processes of industrialization and urbanization. Greenhouse gas and air pollutant emissions produced by the coal-fired power industry represent approximately 70% of the total emissions in China’s industrial sector. In this study, 39 coal-fired power plants built in China between 2014 and 2015 wer...

Introduction The use of microalgae-based bio-mitigation (AEN-116) suffers from a range of challenges primarily related to system complexity and scale-up issues that are driven more by economic constraints than technical limitations. It should be noted that only biological carbon capture and recycling has the potential to generate a revenue stream to offset, at least in part, the overall cost of...

Fired steam generators are the dominating technology of coal combustion in power plants. This paper presents a model for pulverized coal fired steam generators in Modelica. The model components are designed as an extension of SiemensPower, a Modelica library for transient simulation of power plants. The focus is on coal combustion, gas-particle-flow and radiation heat transfer in the furnace. T...

The economic and stable operation was affected seriously by coal quality disturbance for power plants. Based on model analysis, influence of the disturbance can be considered as gain change of control system. Power capability coefficient of coal was constructed to inhibit it. Accuracy of the coefficient was verified by operating data. Then coal quality disturbance free system based on gain sche...

THEODORE J. WEIMAN On July 22, 2004, the House of Representatives passed the Marriage Protection Act of 2004, a bill that would strip the federal courts of jurisdiction over cases challenging the constitutionality of the 1996 Defense of Marriage Act. Two months later, the House passed a similar bill that would curtail federal court jurisdiction for challenges to the constitutionality of the Ple...

With the end of the Supermarket Revolution in the 1970s, new forms of horizontal, vertical, and geographic competition have appeared to chaflenge the supremacy of the supermarket format. New retail formats like warehouse stores, supercenters, and fast-food outlets appear to affect local retail supermarket prices. Slotting allowances, coupons, and electronic data gathering have intensified retai...

The U.S. Environmental Protection Agency has announced plans to regulate emissions of mercury to the atmosphere from coal-fired power plants. However, there is still debate over whether the limits should be placed on a nationwide or a plant-specific basis. Before a nationwide limit is selected, it must be demonstrated that local deposition of mercury from coal-fired power plants does not impose...

We consider whether Sub-Saharan African (SSA) countries are mainly poor because they are governed worse than other countries, as suggested by recent studies on the supremacy of institutions. Our empirical results show that the supremacy of institutions does not hold. SSA countries appear to face specific development problems in addition to weak institutions. Given their geographic and economic ...
