TEPC Completes Erection of Main Boiler Beam for Unit 2 of Nantong Power Plant

---

Researched by Industrial Info Resources China (Beijing, China)--Tianjin Electric Power Construction Company Limited (TEPC) (Tianjin) completed the erection of the first main boiler beam for Unit 2 of China Huaneng Group's (Beijing) Nantong Power Plant Phase III expansion.

The Huaneng Nantong Power Plant, located in Tianshenggang Town of Nantong City, in eastern China's Jiangsu province, was built in 1990. Two 350-megawatt (MW), coal-fired units built in Phase I were completed in March 2009, and two 350-MW units built in Phase II were completed in July 1999. Two 1,000-MW, ultra-supercritical, coal-fired units furnished with high-efficiency, electrostatic dust-removing devices, flue gas desulfurization devices, denitration devices and online continuous monitoring devices will be built in Phase III, with a total investment of about $1.2 billion.

The Phase III expansion project is jointly invested 50:50 by Huaneng Power International Limited (Beijing) and Nantong Tianshenggang Power Generation Company Limited (Nantong, Jiangsu), a subsidiary of China Guodian Corporation (Beijing). East China Electric Power Design Institute (Shanghai), a regional subsidiary of China Power Engineering Consulting Corporation (Beijing), is responsible for the design and engineering of the project.

The project received final approval from the National Development and Reform Commission on September 29, 2011. Construction of the project began in November 2011.

It is the largest coal-fired unit of single-unit capacity in China, and it has a tower-type boiler. The first main beam for the boiler is 31,650 millimeters long, 1,800 millimeters wide and 6,683 millimeters high, and weighs 84 metric tons. So far, about 12,000 metric tons of steel beam have been erected for the boiler at the site. The erection of the main beam of Unit 2 has paved a firm foundation to achieve key milestones in next stage.

According to the schedule, both units of the project will be put into operation in 2013. Upon completion, the total installed capacity of the power plant will be expanded to 3,400 MW.
