Merits of IGCC①Combustor makes coal ash molten form and collects

it on furnace wall by centrifugal force of tangential flow.

② Coal injection at Reductor works as quench to reduce gas temperature below the ash fusion temp.

⇒Preventing the slagging and allowing the use of coal with low ash fusion temp without enlarged gasifier.
