GE Completes World's First DLN1.0+ with Ultra Low NOx Combustion Upgrade on Nine GE 9E Gas Turbines at Five Power Generation Enterprises in China

  • The Project Supports the Shenzhen Municipal Government's "Blue Sky" Air Quality and Public Health Improvement Plan
  • GE's Innovative Upgrade Reduced NOx Emissions from 50mg/m3 (about 25 ppm) to 15mg/m3 (about 7.5 ppm) to Help Five Power Generation Enterprises Meet "Blue Sky" Campaign' Requirements in Record Time
  • Project Marks First Installation of GE's DLN1.0+ with Ultra Low NOx Upgrade on the 9E Fleet and Serves as a Model for Nearly 700 Units in Operation around the World
  • Industry Leading DLN1.0+ with Ultra Low NOx Solution Can Reduce NOx down to 5ppm

Helping to improve air quality and public health throughout China by reducing nitrogen oxide (NOx) emissions, GE (NYSE: GE) today announced that it has successfully completed the world’s first installation of its DLN1.0+ with Ultra Low NOx combustion upgrade on nine GE 9E gas turbines at five power generation enterprises (Shenzhen Nanshan Power Corporation, Shenzhen New Power Corporation, Shenzhen Datang Baochang Gas Power Generation Co. Ltd., Shenzhen Yuhu Power Co. Ltd., and CNOOC Shenzhen Power Co. Ltd.) in Shenzhen. GE unveiled the announcement during the “Shenzhen Blue Sky” DLN1.0+ Retrofit Project Completion Celebration Event it co-hosted with Shenzhen Municipal Ecology and Environment Bureau and Shenzhen Nanshan Power Corporation. More than 100 power plant operators attended the event.  

“Power generation companies are currently facing dual pressure from environmental indicators and economic performance,” said Liang Jianqiang, Head of Shenzhen Nanshan Power Plant. “We continue to search for a two-way solution to help contribute to local blue skies while improving asset performance. GE’s DLN 1.0+ Ultra Low NOx combustion upgrade is a perfect fit for our needs. Through this cooperation, GE has not only confirmed its technological advantage, but also demonstrated its excellent capabilities in execution. With the help of GE, we have succeeded in upgrading our plants while maintaining a steady supply of energy.”

This upgrade reduces NOx emissions from 50mg/m3 (about 25ppm) to 15mg/m3 (about 7.5ppm), thus contributing to Shenzhen Municipal Government’s “Blue Sky” initiative. As part of the initiative, all gas-fired power plants in the city are required to lower its emissions below 15mg/m³ in six months. NOx is a contributor to ground level ozone and reductions in emissions helps improve air quality and public health by making it easier to breathe.  Power plants that fail to comply with these requirements will be taken offline.

"We admire the Shenzhen Municipal Government's adherence to greener and low-carbon development and the efforts to improve the living standards of their citizens,” said Yang Dan, vice president of GE and president, GE Power China. “GE's DLN1.0+ with Ultra Low NOx reduced emissions and is contributing to the Shenzhen Municipal Government’s ‘Blue Sky’ sustainability plan to improve air quality. The successful modernization of nine gas turbines - in a record time of less than six months - provides a reference for many 9E units to repower and adapt to the needs of the new era. GE is proud to bring a real contribution to the ‘blue sky’ battle, and we hope to continue cooperating with more provinces and cities in the future.”

Completed on time, the project mobilized more than 200 experts from China and around the world for factory repairs to meet specific timeframe requirements and exceeded performance expectations. This milestone serves as a model for plant operators that are operating more mature gas turbine fleets in China and around the globe.
