中国燃煤电厂NOx排放估算方法及排放量研究

Study on the estimation methods for NO_x emission from coal-fired power plants in China

综合考虑影响燃煤电厂NOx生成的煤质、燃烧方式、单机容量等客观因素,建立以燃煤发电机组实际排放水平为核心的计算NOx排放量方法,运用数理统计方法,估算出我国2005年燃煤电厂NOx排放量(以NO2计)为671万～781万t。并以2005年为基准,预测在环保要求不变和趋严2种情况下,2010年我国燃煤电厂NOx排放量分别为846万～1003万t和651万～767万t。

Considering the effects on NOx generation in coal-fired power plants, such as coal quality, combustion mode and unit capacity etc., the estimation method of NOx emission was determined cored by actual emission level of coal-fired power plants. According to the estimation results based on mathematical statistics methods, the total NOx emission from thermal power plants was 6.71-7.81 Mt （million ton ） in China in 2005, based on which the NOx emission was projected to increase up to 8.46-10.03 Mt and 6.51-7.67 Mt by 2010 under two cases of similar and more stringent environmental requirements, respectively.
