CO(2) emissions from the US power sector decreased by 8.76% in 2009 relative to 2008 contributing to a decrease over this period of 6.59% in overall US emissions of greenhouse gases. An econometric model, tuned to data reported for regional generation of US electricity, is used to diagnose factors responsible for the 2009 decrease. More than half of the reduction is attributed to a shift from g...

For coal-fired power plants information of the moisture content in the coal is important to determine and control the dynamical behavior of the power plants. E.g. a high moisture content in the coal can result in a decreased maximum load gradient of the plant. In this paper a method for estimating the moisture content of the coal is proposed based on a simple dynamic energy model of a coal mill...

An improved flexible solar-aided power generation system (SAPG) for enhancing both selective catalytic reduction (SCR) de-NOx efficiency and coal-based energy efficiency of coal-fired power plants is proposed. In the proposed concept, the solar energy injection point is changed for different power plant loads, bringing about different benefits for coal-fired power generation. For partial/low lo...

In the early 1990s, hoping to reduce chronic electricity shortages and enhance the efficiency of Chinese power plants, China opened its doors to foreign direct investment (FDI) in electricity generation. Using data from an original survey of US private investors, official Chinese statistics, and other sources, we assess the volume and characteristics of FDI in China's power sector, its impact o...

Use of gasification based on dirty fuels in markets other than syngas production for downstream chemical processes is emerging due to market changes associated with improved gas turbines, deregulation of electric power generation, as well as more and more stringent environmental regulations. Especially for the increasing quantities of opportunity fuels such as refinery residues, biomass and som...

The greatest contribution to greenhouse gas emissions is the burning of fossil fuels, which releases nearly six billion tons of carbon per year into the atmosphere. These fuels will continue to be used well into the 21st century, although there is a urgent need to manage a sustainable economic development. Since power plants are the largest point sources of CO 2 emissions, capturing the carbon ...

Even though efficiency of coal-fired power plant is proportional to operating temperature, increase of operating temperature is limited by a technological level of each power plant components. It is an alternative plan to increase operating pressure up to ultra super critical (USC) point for efficiency enhancement. It is difficult to control the system in that pressure within safety guideline t...

This paper presents recent operating results of Coal Tech s second generation, air cooled, slagging coal combustor, and its application to power plants in the 1 to 20 MW range. This 20 MMBtu/hour combustor was installed in a new demonstration plant in Philadelphia, PA in 1995. It contains the combustion components of a 1 MWe coal fired power plant, a 17,500 lb/hour steam boiler, coal storage an...

As the global financial crisis dethrones the developed world from its economic supremacy, by leading the global economic recovery and growth, the global growth generator (3G) countries are expected to fill the vacuum. Capital market i.e. stock market development can play a crucial role in augmenting such growth in these 3G countries. This study aims at augmenting the determinants of stock marke...
