Table 17-16 Representative Emissions Control Costs for Oil- and Gas-Fired Combustion Gas Turbines.

Source: State and Territorial Air Pollution Program Administrators and the Association of Local Air Pollution Control Officials.

tive emissions control costs for oil- and gas-fired industrial and commercial boilers. Table 17-14 provides representative emissions control costs for technologies applicable to both rich-burn and lean-burn, spark-ignited reciprocating engines. Table 17-15 provides similar data for Diesel- and dual-fuel-fired compression ignition reciprocating engines. Table 17-16 provides representative emissions control cost data for gas-fired and oil-fired combustion gas turbines.

The data contained in these tables should be viewed cautiously, since actual control costs vary widely depending on many application-specific factors. Moreover, due to the recently intensified focus on emissions control, control costs are subject to rapid change as new technologies are developed and existing ones refined. These factors, as well as economies of scale achieved in both manufacturing and field application of control technologies, have generally resulted in decreasing control costs, particularly for smaller capacity systems. Prime examples are SCR and DLN combustion systems for gas turbines. With DLN combustion systems, production costs are relatively low, but there is still a significant capital recovery cost associated with R&D development costs. Additionally, DLN combustors were first only available for very large capacity units. They are now becoming increasingly available for smaller capacity units, with production costs continually decreasing. While SCR systems were first applied in the United States on a very limited basis and at a very high cost, technology advancements and application experience have lowered costs.

Representative cost-effectiveness data should only be used as a general guide and not substituted for technology- and application-specific evaluation. This is particularly important in the field of emissions control, due not only to the rapid changes in the technology, but to the lack of standardization of performance measurement and reporting practices and the variability in field testing conditions. Manufacturer and vendor performance warrantees, with documented standards and testing tolerances, should be considered essential in the purchase and installation of control technologies.

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable.
