MHPS completes construction on Nagasaki coal gasification plant

Mitsubishi Hitachi Power Systems (MHPS) has concluded construction work on a coal gasification furnace plant in Nagasaki, Japan.

The new facility will supply core facilities for integrated coal gasification combined cycle (IGCC) plants.

Work on production of furnaces for IGCC is currently progressing, with a furnace being produced for an IGCC plant in Iwaki, Fukushima. Work is underway on the Iwaki Plant, which will have a capacity of 540MW, with completion expected in June 2018.

A production system, using conventional technologies and newly developed proprietary technologies, has been deployed to manufacture furnaces that can support the high-temperature, high-pressure requirements for coal gasification.

In order to reduce the construction time, furnaces produced at the new plant will be modularised (integrating gasification equipment and pressure containers), and will then be transported to the construction site for installation.

“In IGCC systems, coal is gasified in the gasification furnace and power is generated through a high-efficiency combined cycle that integrates gas and steam turbines. The system is groundbreaking, offering significantly higher efficiency and lower carbon dioxide (CO2) emissions than conventional coal-fired plants,” MHPS said.
