Abstract: As power plants in Hong Kong are the largest emitters of sulphur dioxide, carbon dioxide and nitrogen oxides, etc.; the objectives of this report are to analyse, evaluate and compare test results on flue gas emissions from different power plants of the China Light and Power Company (CLP) in Hong Kong. This study has examined the differences in flue gas emissions from various power plants in the CLP. The emission test results, including sulphur oxides, nitrogen oxides, carbon monoxide, etc., were corrected and summarized for analytical and comparative study. In addition, the report also summarizes and reviews air pollution related legislative requirements and standards pertaining to CLP's electricity generating plants in Hong Kong. Actual emission rates and concentrations were compared with the Government's environmental standards. Furthermore, the benefits of having those air pollution control abatement schemes in position are illustrated, discussed, compared and were supported with corresponding test results. It shows that by the use of NOx reduction burners and low sulphur fuel, emission levels of nitrogen and sulphur oxides can usually reduced significantly. In addition, before and after the fixing of air pollution control abatement schemes, some stack emission data were compared. Meanwhile, air pollution control abatement schemes and improvements are discussed in details and were supported with test results. It shows that by the use of NOx reduction burners and low sulphur fuel, emission levels of nitrogen and sulphur oxides can usually reduced significantly. Conclusively, CLP has committed and continuously making contribution in protecting the environment; these can be shown further by the introduction of natural gas as a new fuel and use of technological advancements for power generation in Hong Kong. The environmental impacts of using natural gas, when comparing with that of using other fossil fuel in conventional units, can be minimal.
