Mitsubishi starts gasified coal power plant in Japan
Mitsubishi Power has completed the construction of an integrated coal gasification combined cycle (IGCC) plant in Iwaki, Fukushima, for Nakoso IGCC Power GK, it said on April 19.
Mitsubishi Power manufactured the core air-blown IGCC system, including the coal gasification furnace. This is the first domestically developed air-blown IGCC system of such large scale in commercial use, the company said.
The project called for the creation of the world's largest IGCC configuration, roughly twice the scale of the Nakoso Unit 10 completed earlier. Compared to Unit 10, power generation efficiency has been substantially enhanced reaching 48%, which was enabled by the gas turbine's having a higher combustion temperature, it said.
“Compared to conventional coal-fired power plants, IGCC plants provide greater power generation efficiency and help to reduce carbon emissions,” Mitsubishi Power said. “For these reasons, they do respond to the needs of power providers in their efforts to make effective use of resources while simultaneously protecting the environment.”
