Title I identifies nitrogen oxides, or NO", as criteria pollutants because of their role in ozone and smog formation and mandates their control in ozone non-attainment areas designated by the United States Environmental Agency. The CAAA also define the idea of ozone transport, and identify the entire Northeast portion of the United States as an ozone transport region that is in non-attainment. Existing major industrial combustion sources in ozone non-attainment areas will most likely be required to installlow-NOx retrofit equipment to reduce emissions by May 1995 under Title I. For any new combustion sources, requirements will be even more stringent, requiring use of the technically most effective means of NO x reduction without regard to cost. Operators would also be required to cut emissions from existing sources to offset any new emissions. State governments are required to form implementation plans and establish specific compliance standards. All combustion devices produce NOx, even natural gas burners. This is particularly true for older have started to introduce 10w-NOx gas burners, even more advanced technology will be needed to meet increasingly stringent requirements. The next generation of low-NO x natural gas burners must be both efficient and cost-effective in order for gas to maintain its place as a preferred industrial fuel. GRI is dedicated to finding practical solutions so that the users of natural gas are provided with cost-effective systems to meet the challenge of the CAAA. In addition, GRI is developing gas-fired approaches that will provide a cleaner, effective alternative to solid and 3 |
