HARBIN - China's first 350-megawatt double-rotor thermoelectric generator has completed 168 hours of test operations in northeast China.

The generator was produced by Harbin Turbine Company, a branch of Harbin Electric Corporation, one of the largest manufacturers of power plant equipment in China, company sources said Sunday.

It features stronger heating supply capacity and more efficient energy use for its double-rotor design, said Guo Pengfei, a researcher at Harbin Turbine.

After being put into operation, it will be able to replace more than 200 coal-burning boilers.
