Supported by CAS Pioneer Initiative and National Natural Science Foundation of China, we developed two core technologies for gasification ash/ slag utilization:
Residual Carbon Combustion Technology
High-Temperature Melting Gasification Technology
Process
Utilizes air/O₂-enriched gas to combust gasification ash /slag, generating steam for power/heat while addressing key challenges:
• Ultra-fine particles
• Low volatile content
• High ignition temperature
Outputs
• Power generation
• Building materials production
Process
Utilizes pure oxygen gasification to pre-activate gasification ash/slag in CGAS gasifier, followed by gasification in a high-temperature entrained flow gasifier.
Outputs
• Syngas for power/chemical production
• Vitrified slag (water-quenched)
Enhanced Heat/Mass Transfer
High Reactivity
Complete Burnout
Stable Steam Output
Low Emissions
Feedstock Flexibility
Preheating & Activation
Energy Efficiency
Equipment Durability
Dual-Use Capability
