Downshot firing technologies for Chinese power generation
- Babcock and Wilcox (United States)
- Shang An Power Plant (China)
The rapid and continuous developing economy in China demands more power. The indigenous coal reserves provide the resource for power demand. Burning low Volatile Matter (VM) coals is a Chinese energy policy. More new power plants burning low VM coals will be planned, and will create an opportunity for boiler suppliers. There are concerns regarding the utilization of low VM coals. The combustion related concerns are the difficulties on ignition, flame stabilization and char burnout. The emission related concern is primarily on the high NOx emissions. The available combustion technologies can handle these difficulties with considerable and acceptable boiler performance, but the high NOx emissions problem remains to be solved. B and W has been dedicated to lowering NOx emissions for many years, and has accumulated a great amount of experience. B and W`s downshot boilers in the Shang An Power Plant are operating efficiently with excellent performance. This paper briefly introduces B and W`s downshot W-flame firing technology and the great achievements at the Shang An Units.
