Ensuring the Environmental Safety of Coal-fired Power Plants for the Flue Gases Purification

Novel catalytic process for flue gas conditioning in electrostatic precipitators of coal-fired power plants.

One of the most important environmental protection problems for coal-fired power plants is prevention of atmospheric pollution of flying ash. The ash particles are typically removed from flue gases by means of electrostatic precipitators, for which the efficiency may be significantly increased by lowering the resistance of fly ash, which may be achieved by controlled addition of microamounts of...

Using bromine gas to enhance mercury removal from flue gas of coal-fired power plants.

Bromine gas was evaluated for converting elemental mercury (Hg0) to oxidized mercury, a form that can readily be captured by the existing air pollution control device. The gas-phase oxidation rates of Hg0 by Br2 decreased with increasing temperatures. SO2, CO, HCl, and H2O had insignificant effect, while NO exhibited a reverse course of effect on the Hg0 oxidation: promotion at low NO concentra...

Increasing the Efficiency of Existing Coal-Fired Power Plants

Coal has long been the major fossil fuel used to produce electricity. However, coal-fired electric power plants are one of the largest sources of air pollution in the United States, with greenhouse gas (GHG) emissions from burning of fossil fuels believed to be the major contributor to global climate change. Regulations under development at the Environmental Protection Agency (EPA) would impose...

Environmental Policy and the Choice of Abatement Technique: Evidence from Coal-Fired Power Plants¤

This paper analyzes the impact of environmental policy instruments on the choice of pollution control techniques. I ̄rst recast the existing theoretical model of pollution abatement technology choice. Previous studies have found that the cost savings to a ̄rm that adopts a technical innovation in pollution control are greater under a market-based instrument, such as an emissions tax or tradeabl...
