Gasification Combined Cycle

Lower Heat Rates and Increased Output. The heat rates of the plants based on IGCC technology are projected to be around 2100 kCal/kWh compared to the heat rates values of around 2500 kCal/kWh for the conventional PC fired plants. 

Flexibility to accept a wide range of fuels. IGCC technology has been proven for a variety of fuels, particularly 

Environment Friendly Technology. IGCC is an environmentally benign technology. The emission levels in terms of NOx, SOx, and particulate from an IGCC plant have been demonstrated to be much lower when compared to the emission levels from a conventional PC fired steam plant.
