Focus on Coal
China’s coal-fired capacity overtakes US
China is continuing to invest in new coal-fired power plants and air pollution control
C
hina has had more coal-fired capacity than the US for some time. It has also had more electrostatic precipitators. Now it has surpassed any country in terms of flue gas desulfurisation (FGD) systems. In the
not too distant future, it will become the number one operator of SCR systems for NOx Control. Te McIlvaine Company tracks each Chinese power
project and also the retrofits of air pollution control systems in a service entitled Chinese Utility Plans. Here are some recent projects:
Coal units approved On July 9, 2010, two 600 MW supercritical units at Datang Huayin Youxian Power Plant were approved by the National Development & Reform Committee. Te two units will consume about 2 900 000 tons of coal each year. On July 18, 2010, under the ‘Build Big & Close
Small’, policy, two units (2×600 MW) at Datang Huaibei Hushan Power Plant were approved by the National Development & Reform Committee. Highly efficient dust removal, FGD and SCR will be installed. On July 22, 2010, No. 3 and No. 4 units (2×1000
MW) at Datang Guangdong Chaozhou Power Plant were approved by the National Development & Reform Committee. Te two ultra supercritical units will be installed with limestone wet FGD and LNB. Te general engineering technology will be designed by American Ever Cleaning Environmental,Inc. On July 9, 2010, two units (2×300 MW) at
Guodian Jilin Longhua Changchun No. 1 Termal Power Plant were approved by the National Development & Reform Committee. Te total investment will be RMB $2.87 billion.
Air Quality Retrofits Te FGD project on the 125 MW No. 5 unit at Huadian Inter Shiliquan Power Plant started construction on April 29, 2010 and will use the wet limestone-gypsum method. Te engineering project general contractor is Wuhan Longjing Environmental Engineering Co Ltd. On May 20, 2010, the SCR system on 1000
MW No 2 unit at Huaneng Yuhuan Power Plant was put into commercial operation after 168- hour trial operation. Te average NOx removal efficiency was 82.53 per cent and the designed NOx removal efficiency was 80 per cent. All four units (4×1000 MW) at Huaneng Yuhuan Power Plant are
Continuous emissions monitors Meanwhile, the world market for continuous emissions monitors (CEMS) for ambient as well as stack applications will exceed $1 billion/yr by 2012. Tis includes the analysers, software and accompanying service revenues.

planned to be retrofit with SCR systems. On June 7, 2010, the SCR system on a 300 MW
unit at Guangdong Yudean Group Power Plant was put into commercial operation after 168-hour trial operation. Tis project started construction on January 16, 2010.
