What is the future of King Coal in China?
When it comes to coal consumption, no other nation comes close to China. The country reigns as the world’s largest coal user, burning almost half of the global total each year. About 70 percent of China’s total energy consumption and nearly 80 percent of its electricity production come from coal, and its recent shift from being a historical net coal exporter to the world’s ...

Horizontal Clarifiers for Coal-Fired Plant
A coal fired power plant and its engineers turned to Monroe Environmental for emergency implementation of a stormwater treatment system upgrade. Coal ash and other solids were clogging existing coalescing oil/water (CPI) separators, plugging the coalescing packs, and allowing solids and oil to bypass the system. After a successful evaluation and pilot test with a rental Monroe plate clarifier, ...

New global assessment reveals nearly 1,200 proposed coal-fired power plants
Coal-fired power plants are a major source of greenhouse gas emissions—one that could be increasing significantly globally, according to new analysis from the World Resources Institute. Several months ago, WRI began compiling and analyzing information about proposed new coal-fired plants in order to assess potential future risks to the global climate. We released our findings today in the ...

Low-volatile coal combustion technologies in Vietnam: issues and strategies
Vietnam has planned to install a number of coal-fired power plants with unit's capacity of up to 600 MW. Present experience shows that available low volatile anthracite coal is difficult to burn in the PC fired boilers. In this paper, the CFB combustion technology is proposed based on the experiences of coal-fired power plants around the world used similar coal characteristics. Later, a ...

Closing the door on building new coal-fired power plants in America
Community opposition, legal challenges, and financial uncertainty over future carbon costs are prompting companies to rethink their plans for coal. Since the beginning of 2007, 95 proposed coal-fired power plants have been cancelled or postponed in the United States--59 in 2007, 24 in 2008, and at least 12 in the first three months of 2009. This covers nearly half of the 200 or so U.S. coal-fired ...

Technical and economic studies on the optimisation of prospective coal-fired power stations
The paper considers problems of choosing rational parameters of thermal power plants on fossil fuel. A technique for comparison of the energy and economic efficiency of prospective coal-fired power plants is described. The optimisation results of parameters of combined-cycle plants with coal gasification at low and high-temperature levels and steam turbine plants on supercritical steam parameters ...

A long year in the life of the US coal industry
With concerns about climate change mounting, the era of coal-fired electricity generation in the United States may be coming to a close. In early 2007, a US Department of Energy report listed 151 coal-fired power plants in the planning stages in the United States. But during 2007, 59 proposed plants were either refused licenses by state governments or quietly abandoned. In addition, close to 50 ...

Coal-fired power on the way out?
The past two years have witnessed the emergence of a powerful movement opposing the construction of new coal-fired power plants in the United States. Initially led by environmental groups, both national and local, it has since been joined by prominent national political leaders and many state governors. The principal reason for opposing coal plants is that they are changing the earth’s climate. ...

Majority of China’s proposed coal-fired power plants located in water-stressed regions
To maintain its economic growth and provide for its massive population, China must reconcile two powerful, converging trends: energy demand and resource scarcity. One prime example of this tension is the country’s coal use and water supply. According to a new WRI analysis, more than half of China’s proposed coal-fired power plants are slated to be built in areas of high or extremely ...

Prime Power Generation - Case Study
A national electricity grid must always be able to meet the needs of its users. This requires it to be: stable, maintaining the required electrical frequency (50 Hz in the UK); balanced, continuously matching supply to demand; and adequate, ensuring total generation capacity is never outstripped by demand. Grid supply is split into three tiers: base, intermediate, and peak load. Baseload is a ...

Eucalyptus plantations for electricity generation: the cost of carbon dioxide abatement in Thailand
Short-rotation plantations are expected to play an important role in the transition towards renewable energy, in particular in many developing countries. At present, developing countries do not have any carbon dioxide (CO2 ) abatement targets under the Kyoto Protocol, but CO2 mitigating projects might nevertheless be carried out through the Clean Development Mechanism (CDM). The purpose of this ...

Opportunities to improve the efficiency of existing coal-fired power plants
Executive Summary Reducing the carbon footprint of energy production activities has emerged as one of the defining environmental issues of the 21st century. The U.S. energy infrastructure encompasses an enormous investment in capital assets and systems to produce fuels and electric power for businesses, transportation, and homes. While the long‐term opportunity to reshape this ...

Air Quality Permitting for a New Coal-Fired Power Plant: A Timeline
The high price of natural gas and alternative fuels has made utility companies take a second look at coal as a cheap, plentiful fuel source. For a greenfield plant considering coal, the environmental considerations are significant but not insurmountable. This article discusses the air quality regulations and permitting requirements that must be addressed, from New Source Review to greenhouse gas ...

Exergoeconomic analysis of a Kalina cycle coupled coal–fired steam power plant
This paper presents exergoeconomic analysis of a Kalina cycle coupled coal–fired steam power plant using specific exergy costing (SPECO) methodology. Cost–balance and auxiliary equations are developed and solved. The results indicate that in the topping cycle, the boiler and the turbine contribute maximum to the formation of product cost. High value of exergoeconomic factor for the boiler ...

The right time for solar augmentation for the CSP industry
While demand for concentrated solar power augmentation of coal-fired plants is picking up with the recent announcement of a 5MW addition to a coal plant in Chile by GDF Suez & Solar Power Group but the fast development of this new market for CSP will only succeed as the costs come down significantly. Last week’s announcement by GDF SUEZ and Solar Power Group of their plans to develop ...

Decommissioning begins at two of largest U.S. coal-fired power plants
Navajo Generating Station, a 2.25-GW coal plant in Arizona, closed in November after 45 years of providing power. Owner Salt River Project (SRP) said it was uneconomical to continue operating. The focus has now shifted to decommissioning, long-term monitoring and ongoing operation of the transmission system. Working with SRP, a number of U.S.-based contractors will conduct demolition and ...

Analysis of U.S. coal plant retirements case study
In 2010, MJB&A completed a report for a major natural gas transmission company of coal-fired electricity generating units (EGUs) in several different geographic regions and their potential for retirement and/or to repower with natural gas. This analysis developed an indicative model of future coal-fired power plant repowerings and retirements based on a range of operational and market ...

Biomass Ready Coal Fired Plants and Massive Tree Planting will be the Compromise Climate Change Solution
Coal provided 26 percent of the additional power generation last year and 38 percent of all generation. There are 500,000 MW of new coal fired generation in the planning stage. This is more than was ever installed in the Americas and Europe. So any programs to reduce coal fired generation on these two continents to zero would eliminate less than is being added elsewhere in the world. The ...

Permit Compliance Monitoring for the Power Generation Industry
The Clean Air Act Amendments (CAAA) of 1990 authorized EPA to develop regulations requiring facilities to monitor the adequacy of emission control equipment and plant operations. This paper discusses the various methods available for coal-fired power plants and gas turbine installations to demonstrate a reasonable assurance of facility compliance with emission limitations, and ensure that control ...
