Abstract

The activity data and technical information of coal-fired power units in China from 2011 to 2015 were collected. A NO_x emission calculating model and an emission database was developed for coal-fired power plants. And the NO_x emissions characteristics of coal-fired power plants in China from 2011~2015 were analysed. NO_x emissions increased from 10.73million tons in 2010 to 11.32million tons in 2011, then decreased in the following 4years, to 5.22million tons in 2015. The layout of NO_x emissions is uneven. Inner Mongolia, Shandong, Jiangsu, Jiangxi, Henan, Hebei and Liaoning contributed 48.8% of total NO_x emissions from Chinese coal-fired power plants in 2015. Shanghai, Jiangsu, Tianjin, Ningxia, Shandong, Zhejiang and Shanxi ranked top 7by emission intensity. Units with capacity between 300MW and 600MW contribute the largest part of NO_x emissions. The average NO_x emission performance of 100MW level units was 2.91g/kWh, and which of 1000MW level units was 0.48g/kWh. The larger units performs better in terms of emissions because they apply better technology and install more advanced pollution abatement facilities.

Key words： power plant NO_x emission characteristics emission inventory China
