• Minimum Utility Consumption by MHI O2-Blown Gasifier for Syngas Production
• Effective Utilization of By-Product like Discharged Molten Slag, Recovered Sulfur, etc.
• High Plant Efficiency by “G” Type High Temp. GT and High Reliability from Abundant “Low BTU Gas Firing” GT
Realizes the Lowest Cost with Various Advantages
• Flexibility for Variety of Coal Including Brown Coal Because of 2-Staged Dry Coal Feed and “Fine” Coal Pulverizing System
• Higher Reliability & Easier Maintainability with Membrane Waterwall Configuration
Features of MHI IGCC / GasifierFeatures of MHI IGCC / Gasifier
• Highest Plant Efficiency Because of Air-Blown Gasifier for IGCC
