New Prospects for High Sulfur Coal

Advances in combustion methods permit the burning of nasty coal with dramatically fewer emissions.

"Circulating fluidized bed combustors are relatively new to the electric power industry. They promise lower capital costs, lower pollution-control costs, better pollution control, fuel flexibility and higher combustion efficiency. Those qualities translate into moderate electricity costs for consumers.

While conventional coal-fired plants required expensive add-ons to clean pollutants from flue gases after combustion, fluidized-bed technology captures most of them inside the boiler during combustion."
