Abstract |
The paper discusses forecasts of industrial combustion emissions being developed by the U.S. EPA as part of the National Acid Precipitation Assessment Program (NAPAP). The Industrial Combustion Emissions (ICE) Model will estimate sulfur dioxide (SO2), nitrogen oxides (NOx), and primary sulfate emissions from industrial fossil-fuel-fired boilers. These forecasts will be generated on a state-level basis. Alternative pollution control scenarios will be evaluated for reducing emissions from both existing and new industrial boilers. The ICE Model also evaluates the selection of fossil fuels for industrial steam generation. Capital and operating/maintenance costs for boilers and pollution control equipment, plus the costs of alternative fuel types, are used in selecting the fuel type for individual industrial boilers. Since emission rates vary significantly between coals, residual fuel oils, and natural gas, the fuel choice decision is a critical factor in estimating aggregate levels of SO2, NOx, and primary sulfates. |
