Currently, many socially responsible governments adopt economic incentives and deterrents to manage environmental impacts of electricity suppliers. Considering the Stackelberg leadership of the government, the government’s role in the competition of power plants in an electricity market is investigated. A one-population evolutionary game model of power plants is developed to study how their pro...

Coal preparation is the first step in the whole process of coal-fired power generation. A typical milling process is illustrated in Figure 1. Also, coal-fired power stations nowadays are required to operate more flexibly with more varied coal specifications and regularly use coal with higher volatile contents and Biomass materials (Livingston 2004); this greatly increases the risks of explosion...

In January 2012, the Sierra Club and the Kosovo Institute for Development Policy (INDEP) issued a report entitled Re-evaluating Kosovo’s Least Cost Electricity Option (Sierra Club/INDEP Report). 1 This report evaluated the World Bank’s proposed Kosovo Power Project, as described in the Bank’s December 2011 study, Development and Evaluation of Power Supply Options for Kosovo: A Background Paper ...

Mercury rule lets hazardous air pollutants off the hook O n March 15, the U.S. EPA issued the long-awaited and controversial rule establishing trading as the mechanism for reducing mercury emissions from coal-fired plants. Although the debate over the rule focused on how best to control mercury releases, critics say that an opportunity to also regulate several other hazardous air pollutants (HA...

There have been contradictory reports of the relative proportion of mercury from coal-fired power plants that deposits locally. Our objective was to determine any local effect of coal-fired power plants on total mercury concentrations in wetland sediment and tadpole samples. Four power plants and 45 wetlands were selected for study. Total mercury concentrations were determined in 75 sediment sa...

Executive Summary The Clean Coal Technology (CCT) Demonstration Program is a government and industry co-funded effort to demonstrate a new generation of innovative coal utilization processes in a series of " show-case " facilities built across the country. These projects are carried out on a sufficiently large scale to prove technical feasibility and provide the information required for additio...

In this paper, an improved system to efficiently utilize the low-temperature waste heat from the flue gas of coal-fired power plants is proposed based on heat cascade theory. The essence of the proposed system is that the waste heat of exhausted flue gas is not only used to preheat air for assisting coal combustion as usual but also to heat up feedwater and for low-pressure steam extraction. Ai...

Coal ash is the main waste from power plant. It is estimated that the consumption of the coal for power plant will increase to 240 million tons each year and the coal ash wastes will produce more than 2 million tons per year. Although the utilization of coal fly ash can be reached 74.1%, large amount of coal fly ash and bottom ash still cannot be utilized. The purpose of this research is to dev...
