The high enthalpy steam generated during coal Demonstration: First Step / Oxygen-blown IGCC. Coal is gasified in the gasifier to generate syngas with carbon monoxide (CO) and hydrogen (H 2) being the mainponents. After this, the heat of the syngas is recovered in a syngas cooler and a gas clean-up unit removes impurities and sulfur from the syngas.
