The No. 2 unit of China Huaneng Group's (Beijing) Changchun Thermal Power Plant passed the 168-hour trial operation and began commercial operations on April 17, 2010. This marks the first fully completed supercritical combined heat and power project in China, according to an announcement of Northeast Electric Power Design Institute (NEPDI) (Changchun, Jilin), a regional subsidiary of China Power Engineering Consulting Group Corporation (Beijing), on April 19.
Huaneng Changchun Thermal Power Plant is in Helong Town of Nong'an County, which is about 18 kilometers to Changchun, the capital city of Jilin province. The power plant has a total planned capacity of 1,200 megawatts (MW). Two 350-MW supercritical combined heat and power units, together with flue gas desulfurization and denitration devices, were built in Phase I.
Construction on the project kicked off in June 2008, and the first unit was commissioned in December 2009. It took only 18 months from the commencing of construction to the commissioning of the project, which is record for a 350-MW supercritical unit project, given the cold weather in northeast China.
The project is solely invested by Huaneng Jilin Power Generation Company Limited (Changchun, Jilin), a regional subsidiary of China Huaneng Corporation. NEPDI is responsible for the design and engineering of the project.
The project uses lignite with high water content as its fuel, and is adopted with board heat exchanger and urban intermediate water as its water supply. During the engineering phase, the designer attached high importance to energy conservation and environmental protection, as well as the application of new technologies and new processes based on the principles of "high quality, high speed and low cost."
