2.1. Flexibility
Syngas
Waste FlexibilityMainly MSW or RDF with other waste
This system has high waste flexibility and requires no pre-treatment. No pre-treatment High temperature gasification (>1,800 C) Double damper system (max. 800 mm)
CfD Eligible Continuous syngas measuring Stable combustion Approx. 5.9 MJ/m3
N based on 9.1 MJ/kg-waste refer to N.Tanigaki et. al. Waste Management
1,800℃

3.2.1. Environmental Friendly
(1) Low Emissions Syngas combustion (homogeneous combustion) 3Ts (Time, Temperature, turbulence) Lower emissions such as PCDD/DFs, HCl and SO2 have positive impact for achieving permissions.
(2) Energy and Material Recovery from Waste - Recycling material from waste without further post- treatment - Minimizing non-recyclables and landfill amount - Contributing to “Circular Society” or “Zero Waste”

3.3.1. Sustainability - Energy from Waste -
- Horizontal Boiler- η : >28% (11 MJ/kg, 10t/h x 2 lines)
- Dust Removal: Rapping system Shower Cleaning Soot Blower for EconomizerLower maintenance problems
- Combustion chamber is also the part of the boiler

3.4.5. Reliability - Operating Support -
(1) PlantPAD
Monitored operating condition remotely Inspection data is recorded Checking operating data - ITV - Historical trend data - On-time operating condition easier maintenance management
(2) Predictive Operating
Many operating records can predict the operating conditions. Several parameters are picked up for predictive operation. Less operation load
These supporting system lead easier “O&M” of gasification technology

4. Summary
NSENGI Group has a capability to provide various solutions for clients. (gasification, incineration and others)
The Direct Melting System can achieve both the energy and material recovery from waste without any pre- and post treatment.
Driving factors of waste gasification for deployment are (1) Flexibility of waste (2) Environmental Friendly (3) Sustainability (Energy and Material recovery) (4) Reliability
Especially, our waste flexibility have great possibility to contribute to “Circular Society” and to improve feasibility of the project.
