2.1. Flexibility
Waste Flexibility
Mainly 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)
Sewage sludge
Bottom ash
Landfill Waste
Clinical Waste
CfD Eligible
Syngas
400500 ℃
600
-800 ℃
1,800℃
Continuous syngas measuring
Stable combustion
Approx. 5.9 MJ/m3N based on 9.1 MJ/kg-waste
refer to N.Tanigaki et. al. Waste Management

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 Economizer

Operation & Maintenance
 Bottom ash recycling is not allowed
.
 The municipality has no landfill site
 Need solutions. Co-Gasification and recycling
 87% reduction of final landfill amount

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.
