Mitsubishi Heavy Industries Ltd. said Thursday it has secured an order from South Korea's Posco Power Co. for two sets of power generation systems that use gases released as a result of iron production.

The equipment, the third such order from the Posco group, is to be delivered between 2012 and 2013 for use at an ironworks of the parent firm Posco, South Korea's largest steelmaker, in Pohang. The value of the order was not disclosed.

Each set will include gas and steam turbines, gas compressors and dust collectors, and will be used to generate 145 megawatts of electricity, Mitsubishi Heavy said, adding Mitsubishi Electric Corp. will supply the generators.
