Coal Power Plant - Juliette, Georgia, USA - Project
The baghouse project shown for Southern Company, was fabricated by CPF in Ontario, Canada and truck shipped in panelized form to site for erection. After 20,000,000 lbs of fabrication and 600 shipments, site issues were minimal and amounted to less than 0.01% in backcharges. We are fabricators with a proven track record of minimal field issues due to our commitment of trial fitting components ...

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 ...

An environmentally conscious robust optimisation approach for planning power generating systems
This study proposes a robust optimisation capacity expansion planning model that yields a less sensitive solution due to variations in model parameters such as demand and fuel prices. By adjusting the penalty parameters, the model can accommodate the decision maker's risk aversion and yield a solution based upon it. The proposed model is then applied to Ontario Power Generation, the largest power ...

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 ...

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 ...

Solar Energy has Little Impact on Birds
People are not worried about the pollution coming from the renewable energy sources, because most of them do not produce significant amounts of pollution. The supplies, the process of how the supplies come to the source and the demolishing machines used to erect these renewable energy sources are the true culprits wreaking havoc environmentally. For instance, older wind turbines have a negative ...

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. ...

The impacts of technological learning on the optimum technology mix: simulations for the Indian power sector
For the investigation of the optimum technology mix of any country, which is clearly an issue of dynamic nature, technological learning and economies of scale play a significant role. Hence, in this paper's long term planning exercise for the Indian power sector (2000-2025), our simulation analysis specifically includes the impacts of technological learning on the optimal inter-temporal choice of ...

President Obama’s Climate Action Plan: Can it Shift the World Away from Coal?
While reactions to President Obama’s newly announced climate plan have focused on domestic action, the plan actually has potentially significant repercussions for the rest of the world. These repercussions will come in part through his commitment to limit U.S. investments in new coal-fired power plants overseas. If fully implemented, the plan will help ensure that the U.S. government ...

Thermo-economic efficiency of low capacity coal-based power plants
The method of estimation of thermo-economic factors, allowing the justification of the construction of low capacity coal-based power plants has been developed in the present paper. The C-curve method applied for thermo-economic analysis is used here for determination of the optimal ratio between specific exergetic and cost-performance factors. The results of the analysis show that for coal-based ...

Coal is abundant, let’s burn it responsibly
China coal stocks fully loaded right along with record setting power output China’s coal inventories at power plants are full despite recent record power generation, according to China’s National Development and Reform Commission. At the present the China’s coal supply and demand was stable. Lots of coal ready to burn. China’s daily power generation surged to a new high ...

Integration of Fischer-Tropsch fuel production with a complex oil refinery
The oil refining industry is facing harder policies on renewable content in its products. One way to meet this is to produce diesel and gasoline from gasification of biomass via a Fischer-Tropsch (FT) synthesis. In this paper, heat integrating a biomass-to-FT syncrude process with a refinery is compared to a stand-alone biomass-to-FT syncrude process, in terms of the consequences for GHG ...

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 ...

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 ...

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 ...
