AEPC1 Completes Stator Erection for Unit 2 of China Guodian's Karamay Cogeneration Project

---

Researched by Industrial Info Resources China (Beijing, China)--Anhui Electric Power Construction No.1 Engineering Company (AEPC1) (Hefei, Anhui), a subsidiary of China Energy Engineering Corporation (CEEC) (Beijing), completed the erection of a generator stator for Unit 2 of China Guodian Corporation's (Beijing) 700-megawatt (MW) Karamay Cogeneration Power Project on May 6, 2013. The erection of Unit 2 has entered a peak period, according to an announcement from the CEEC on May 10.

As reported, the generator stator of Unit 2 has a net weight of 192 metric tons, which is the heaviest single piece in the entire unit. The erection was carried out by two bridge cranes in the powerhouse, which were supported by a hydraulic lifting device.

The Guodian Karamay Cogeneration Project, located in the Petroleum and Chemical Industrial Park of Karamay, has a total planned capacity of four 350-MW, coal-fired units for a combined heat and power (CHP) supply in Karamay; of these, two 350-MW, supercritical, direct air-cooling extraction condensing CHP units, together with flue gas desulfuration and nitrogen emission controls, are being built in Phase I. As a support project for PetroChina's 10 million-metric-ton oil refining expansion project in Karamay, the project was listed as a key project in both the Xinjiang autonomous region and Karamay City early in 2010.

AEPC1 won the bid for the construction and erection of Unit 2 as well as the coal handling and preparation system of the project, in early 2011. The other unit was contracted to Shandong Electric Power Construction No.3 Engineering Company Limited (Qingdao, Shandong).

Construction of Unit 2 kicked off on June 8, 2011 but the project didn't receive final approval from the National Development and Reform Commission until February this year.

According to the latest schedule, both units of the project will begin operations in October 2013. Upon completion, the project will be able to generate about 3.5 billion kilowatt-hours of electricity per year and an annual heat supply capacity of about 11.2 million gigajoules per year, which can supply heat for an area of 12 million square meters.
