Mitsui Engineering offers generators carbon pellet fuel

30 July 2004 – Mitsui Engineering & Shipbuilding Co. is targeting power companies interested in using carbon pellets in place of coal in their power plants. The company has developed a garbage incineration system that features a gasification-melting furnace and equipment that processes the residual carbon into pellets that can be used as a fuel to generate electricity.

Gasification-melting furnaces are often coupled with a boiler in order to harness the heat from garbage incineration to generate electricity, but the process has an energy efficiency of only around 20 per cent.

By taking the carbon dust that is left after garbage is incinerated and solidifying it into pellets that can be burned as a fuel, the electricity-generating efficiency can be boosted to 35 per cent.
